Would you like to inspect the original subtitles? These are the user uploaded subtitles that are being translated:
1
00:00:03,710 --> 00:00:15,928
it's okay now yeah okay yeah okay
2
00:00:14,160 --> 00:00:19,469
receive the pictures of the motherboard
3
00:00:15,929 --> 00:00:22,518
boy is like low resolution it's not
4
00:00:19,469 --> 00:00:26,579
loaded solution but it's not very good
5
00:00:22,518 --> 00:00:29,368
so what is the problem you wanted to get
6
00:00:26,579 --> 00:00:31,348
them closer no it's okay just just tell
7
00:00:29,368 --> 00:01:15,000
me what do you check and what do we have
8
00:00:31,349 --> 00:01:31,909
there she know yet yes and I have the
9
00:01:15,000 --> 00:01:31,908
picture here yeah okay so yeah yes okay
10
00:01:44,328 --> 00:01:49,250
let me grab the other picture one second
11
00:01:53,390 --> 00:02:04,109
okay okay so you found the four but you
12
00:02:03,269 --> 00:02:06,450
know what
13
00:02:04,109 --> 00:02:09,830
oh and this you see how is the picture
14
00:02:06,450 --> 00:02:12,239
now yeah how is the motherboard now yeah
15
00:02:09,830 --> 00:02:13,750
let's plug the charger and let's check
16
00:02:12,239 --> 00:02:19,719
together some voltages on
17
00:02:13,750 --> 00:02:21,400
more yeah that's good okay yeah he's not
18
00:02:19,719 --> 00:02:23,800
a point you know checking for the first
19
00:02:21,400 --> 00:03:19,780
on MOSFETs if we have 19 volts on the
20
00:02:23,800 --> 00:03:21,580
board charger all right yeah that's
21
00:03:19,780 --> 00:03:24,099
great so check the voltage is the
22
00:03:21,580 --> 00:03:29,890
voltage on the connector on the charging
23
00:03:24,099 --> 00:03:35,919
charger connector there yeah that's
24
00:03:29,889 --> 00:03:41,349
great you know on the other side yeah
25
00:03:35,919 --> 00:03:49,208
you have the let me see whatever we can
26
00:03:41,349 --> 00:03:51,250
check for now I want to check the 19
27
00:03:49,209 --> 00:04:02,199
first and I'm just looking for a power
28
00:03:51,250 --> 00:04:05,799
supply and those capacitors okay you are
29
00:04:02,199 --> 00:04:08,969
there sorry one second let me change the
30
00:04:05,799 --> 00:04:08,969
picture one second
31
00:04:15,229 --> 00:04:23,150
okay you see where is the processor
32
00:04:18,509 --> 00:04:27,169
socket there okay
33
00:04:23,149 --> 00:04:30,448
under the processor socket yeah you have
34
00:04:27,168 --> 00:04:32,549
some capacitors there there exactly
35
00:04:30,449 --> 00:04:35,430
there no no no no where you put the
36
00:04:32,550 --> 00:04:38,699
finger first time down there check with
37
00:04:35,430 --> 00:04:47,519
the mood yeah that capacitor check with
38
00:04:38,699 --> 00:04:54,410
the multimeter the voltage there okay on
39
00:04:47,519 --> 00:04:59,459
the other side okay go up to the other
40
00:04:54,410 --> 00:05:07,520
capacitors once it's not about ooh too
41
00:04:59,459 --> 00:05:08,698
much there check there please okay dokay
42
00:05:07,519 --> 00:05:11,219
okay
43
00:05:08,699 --> 00:05:14,930
I was thinking of the processor one so
44
00:05:11,220 --> 00:05:17,430
we don't have 19 volts there true or not
45
00:05:14,930 --> 00:05:19,590
okay take out the the charging port
46
00:05:17,430 --> 00:05:21,650
connector and let's check together let's
47
00:05:19,589 --> 00:05:28,049
let's start from the charging port and
48
00:05:21,649 --> 00:05:32,758
let's follow the 19 volts power okay
49
00:05:28,050 --> 00:05:36,270
that's good now let's go on the on the
50
00:05:32,759 --> 00:05:40,288
on the connector on the charger charger
51
00:05:36,269 --> 00:05:42,839
connector there yeah yes and now switch
52
00:05:40,288 --> 00:05:44,939
the the multimeter on the diode mode on
53
00:05:42,839 --> 00:05:50,000
the beeping mode you see that read the
54
00:05:44,939 --> 00:06:01,319
thing now let's find the first MOSFET
55
00:05:50,000 --> 00:06:17,668
where is the first MOSFET yeah you can
56
00:06:01,319 --> 00:06:19,649
take it away yeah yeah yeah I can see
57
00:06:17,668 --> 00:06:22,978
well obviously you understand I can't
58
00:06:19,649 --> 00:06:25,839
see what you see so you have to go from
59
00:06:22,978 --> 00:06:28,300
the the plus yeah
60
00:06:25,839 --> 00:06:38,229
and go on the MOSFETs and see which
61
00:06:28,300 --> 00:06:40,360
MOSFET the voltage is going doesn't
62
00:06:38,230 --> 00:06:42,819
matter know if that's it's it's an
63
00:06:40,360 --> 00:06:51,460
continuity more than is not important
64
00:06:42,819 --> 00:06:58,509
plus or minus one second let me grab the
65
00:06:51,459 --> 00:07:00,250
other picture you are on the side with
66
00:06:58,509 --> 00:07:02,519
the connector yeah we need a charging
67
00:07:00,250 --> 00:07:02,519
connector
68
00:07:04,529 --> 00:07:08,978
the thing is this that the picture is
69
00:07:07,000 --> 00:07:21,389
not complete what do we have on the end
70
00:07:08,978 --> 00:07:21,389
of the board yes there understand
71
00:07:23,250 --> 00:07:37,589
[Music]
72
00:07:24,600 --> 00:07:38,800
okay what about I can't see nothing here
73
00:07:37,589 --> 00:07:40,779
hmm
74
00:07:38,800 --> 00:07:44,228
I think it's going on the other side you
75
00:07:40,779 --> 00:07:48,609
can check you can keep the we can check
76
00:07:44,228 --> 00:08:06,699
for beeping yeah the header let me check
77
00:07:48,610 --> 00:08:09,189
one second switch okay but you have to
78
00:08:06,699 --> 00:08:11,589
you have to keep one of the multimeter
79
00:08:09,189 --> 00:08:22,120
probe yeah on the plus of the charge
80
00:08:11,589 --> 00:08:24,339
report okay so he sold out there that's
81
00:08:22,120 --> 00:08:27,699
great that's great okay so keep there
82
00:08:24,339 --> 00:08:29,109
and search for the MOSFETs I can see on
83
00:08:27,699 --> 00:08:31,769
the end of the board I can see our
84
00:08:29,110 --> 00:08:31,770
MOSFET there
85
00:08:33,219 --> 00:08:37,620
on which one just
86
00:08:37,929 --> 00:08:41,589
by the charger
87
00:08:41,889 --> 00:08:49,639
he's beeping there on how many pins is
88
00:08:44,929 --> 00:09:00,699
beeping how many pins no no check on the
89
00:08:49,639 --> 00:09:00,699
the the mosfet pins on all four yeah
90
00:09:01,149 --> 00:09:06,919
okay go on the other side
91
00:09:03,559 --> 00:09:09,309
yeah go on the other side and check no
92
00:09:06,919 --> 00:09:17,479
no no on the other side of the MOSFET
93
00:09:09,309 --> 00:09:26,269
and check with the ground please nothing
94
00:09:17,480 --> 00:09:30,560
yeah he's no important so now now we
95
00:09:26,269 --> 00:09:32,840
have to find the second MOSFET try to
96
00:09:30,559 --> 00:09:35,149
check from the from the output of the
97
00:09:32,840 --> 00:09:38,090
MOSFET from the output now you have to
98
00:09:35,149 --> 00:09:40,939
keep one of the output output yeah and
99
00:09:38,090 --> 00:09:46,759
try to find the next one try to see
100
00:09:40,940 --> 00:09:48,970
where it's beeping how many pins are
101
00:09:46,759 --> 00:09:48,970
beeping
102
00:10:00,220 --> 00:10:07,190
three three that's good that's good and
103
00:10:04,429 --> 00:10:12,649
check on the other side of that MOSFET
104
00:10:07,190 --> 00:10:17,020
with the ground no no with the ground
105
00:10:12,649 --> 00:10:17,019
from the output of the second MOSFET
106
00:10:25,090 --> 00:10:42,580
it's like he gives a little like big and
107
00:10:29,139 --> 00:10:42,580
disappears okay one second would say
108
00:10:50,919 --> 00:10:59,779
okay you have a green thing there next
109
00:10:54,169 --> 00:11:02,120
to the MOSFET you have a green thing you
110
00:10:59,779 --> 00:11:05,240
can check from that MOSFET if the output
111
00:11:02,120 --> 00:11:11,289
of that MOSFET go to that resistor it's
112
00:11:05,240 --> 00:11:12,529
a green thing yeah okay now yeah now now
113
00:11:11,289 --> 00:11:16,519
sorry
114
00:11:12,529 --> 00:11:18,860
yeah those are the MOSFETs now keep keep
115
00:11:16,519 --> 00:11:21,500
one on that resistor on the green one
116
00:11:18,860 --> 00:11:23,690
and with the with the other probe of the
117
00:11:21,500 --> 00:11:26,000
multimeter go under on those capacitors
118
00:11:23,690 --> 00:11:27,380
from the beginning you know in the
119
00:11:26,000 --> 00:11:32,299
beginning when I told you to check the
120
00:11:27,379 --> 00:11:34,759
capacitors it doesn't matter that there
121
00:11:32,299 --> 00:11:40,250
is history like 0.1 ohms so it's no
122
00:11:34,759 --> 00:11:44,779
important not there down so it's going
123
00:11:40,250 --> 00:11:46,580
there okay so does that adopt us our 19
124
00:11:44,779 --> 00:11:50,360
volts power I'll check with the ground
125
00:11:46,580 --> 00:11:56,320
now with the ground from the green
126
00:11:50,360 --> 00:11:58,940
resistor to the ground nothing
127
00:11:56,320 --> 00:12:00,110
so you seen in this case we don't have
128
00:11:58,940 --> 00:12:05,750
short to the ground
129
00:12:00,110 --> 00:12:08,990
okay okay what do we need now we need
130
00:12:05,750 --> 00:12:16,850
the charge of word to see exactly where
131
00:12:08,990 --> 00:12:24,049
the yeah yeah that's what we have to do
132
00:12:16,850 --> 00:12:33,379
next to see which one is close and you
133
00:12:24,049 --> 00:12:35,589
know which one really so you checked
134
00:12:33,379 --> 00:12:35,590
already
135
00:12:36,049 --> 00:12:40,609
reg you the email I checked everything
136
00:12:37,909 --> 00:12:42,769
and I just wanted to double-check it am
137
00:12:40,610 --> 00:12:44,919
I right on that that's great that that's
138
00:12:42,769 --> 00:12:44,919
fantastic
139
00:12:55,629 --> 00:13:01,100
that's normal you you think I never
140
00:12:58,220 --> 00:13:16,879
messed up it does not model these things
141
00:13:01,100 --> 00:13:19,209
happen don't worry about that okay you
142
00:13:16,879 --> 00:13:19,208
know what
143
00:13:20,419 --> 00:13:25,250
you should put some something under the
144
00:13:23,000 --> 00:13:27,740
motherboard because the the plastic is
145
00:13:25,250 --> 00:13:33,409
to be metal over you see that the red
146
00:13:27,740 --> 00:13:35,528
things yeah yeah okay that's good that's
147
00:13:33,409 --> 00:13:35,528
good
148
00:13:38,019 --> 00:13:42,139
so check straight on the other side you
149
00:13:40,879 --> 00:14:20,720
don't have to keep the board in this
150
00:13:42,139 --> 00:14:25,328
side not on on volts
151
00:14:20,720 --> 00:14:25,329
yeah volts okay that's good
152
00:14:28,230 --> 00:14:49,539
19 okay and after that one yes that's
153
00:14:37,659 --> 00:14:51,250
not good and when you put the power
154
00:14:49,539 --> 00:15:04,029
supply on the other side what happened
155
00:14:51,250 --> 00:15:05,860
is short with the power supply okay
156
00:15:04,029 --> 00:15:08,250
take out the charger take out the charge
157
00:15:05,860 --> 00:15:11,580
unless do something together here now
158
00:15:08,250 --> 00:15:23,710
set up the power supply oh 19 volts
159
00:15:11,580 --> 00:15:26,259
around 2 amps no but I know you know I
160
00:15:23,710 --> 00:15:28,300
know based on the way the arrow is on
161
00:15:26,259 --> 00:15:31,120
the off the button but does the matter
162
00:15:28,299 --> 00:15:34,479
is no important to films is no important
163
00:15:31,120 --> 00:15:36,940
just and I want to come with you with
164
00:15:34,480 --> 00:15:39,960
the - to ground and with the Plus on the
165
00:15:36,940 --> 00:15:39,960
green resistor
166
00:15:48,929 --> 00:16:04,659
Jeanne and I think the problem was an
167
00:16:01,149 --> 00:16:06,429
other side know on the green resistor
168
00:16:04,659 --> 00:16:20,319
yeah and check on the power supply what
169
00:16:06,429 --> 00:16:23,679
happened 3.3 volts and how many amps but
170
00:16:20,320 --> 00:16:28,110
you can set up more amps I can yeah go
171
00:16:23,679 --> 00:16:40,059
up two amps
172
00:16:28,110 --> 00:16:44,580
tell me the voltages see what is getting
173
00:16:40,059 --> 00:16:49,269
hot something must get get hot check on
174
00:16:44,580 --> 00:17:00,520
really you see you don't even need me
175
00:16:49,269 --> 00:17:34,240
okay which place is getting hot okay
176
00:17:00,519 --> 00:17:39,700
okay so I check the both yes it's almost
177
00:17:34,240 --> 00:17:41,049
in the middle between these two no r22
178
00:17:39,700 --> 00:17:48,819
MOSFETs one big one small
179
00:17:41,049 --> 00:17:52,089
if I'm right one second is the car
180
00:17:48,819 --> 00:17:54,119
either are two MOSFETs a big one and a
181
00:17:52,089 --> 00:17:56,539
small one
182
00:17:54,119 --> 00:18:06,349
[Music]
183
00:17:56,539 --> 00:18:10,129
liquid which liquid from where yeah okay
184
00:18:06,349 --> 00:18:16,789
yeah and the big one and the big one it
185
00:18:10,130 --> 00:18:20,919
is doing no no I believe you one second
186
00:18:16,789 --> 00:18:20,918
one second that's a power supply yeah
187
00:18:23,950 --> 00:18:27,529
not the boat dot dot the big one and the
188
00:18:26,990 --> 00:18:38,720
small one
189
00:18:27,529 --> 00:18:44,240
two MOSFETs and they okay that will not
190
00:18:38,720 --> 00:18:46,700
help me no no so that most what is
191
00:18:44,240 --> 00:18:52,339
getting hot so if you check with the
192
00:18:46,700 --> 00:18:53,900
multimeter actually son short okay let's
193
00:18:52,339 --> 00:19:10,668
check with the multimeter on on the
194
00:18:53,900 --> 00:19:14,740
coils you have two coils there yes on
195
00:19:10,669 --> 00:19:14,740
the coils on the coils
196
00:19:18,640 --> 00:19:38,500
it's like little done like what about
197
00:19:24,759 --> 00:19:40,000
other quail sale okay okay let's check
198
00:19:38,500 --> 00:19:41,339
that the two MOSFETs you have their two
199
00:19:40,000 --> 00:19:47,109
most vicek for short
200
00:19:41,339 --> 00:19:48,788
the both MOSFETs yeah but I want to
201
00:19:47,109 --> 00:19:53,428
check for short with the probes on one
202
00:19:48,788 --> 00:19:53,429
side on the other side of the MOSFETs
203
00:19:53,970 --> 00:20:01,000
yeah but check on the other side with
204
00:19:57,028 --> 00:20:02,859
you understand both probes want one of
205
00:20:01,000 --> 00:20:04,690
the problem those side of the MOSFET and
206
00:20:02,859 --> 00:20:12,428
the other probe on the other side of the
207
00:20:04,690 --> 00:20:14,080
MOSFET you understand what I mean no no
208
00:20:12,429 --> 00:20:18,669
where is the blocked probe because I
209
00:20:14,079 --> 00:20:24,928
can't see the black one the multimeter
210
00:20:18,669 --> 00:20:24,929
probe the multimeter wire the black wire
211
00:20:25,048 --> 00:20:30,700
okay now check with the one side via
212
00:20:29,109 --> 00:20:31,269
from the one side to the other side not
213
00:20:30,700 --> 00:20:34,509
to the ground
214
00:20:31,269 --> 00:20:41,470
no to the ground okay you know what I
215
00:20:34,509 --> 00:20:49,138
mean yeah it's no sure okay check the
216
00:20:41,470 --> 00:20:49,139
small one please okay check us yes
217
00:20:54,380 --> 00:21:25,399
nice no short okay okay and that MOSFET
218
00:21:06,349 --> 00:21:27,918
you said yeah yeah but does the thing
219
00:21:25,398 --> 00:21:32,239
maybe the MOSFET is good and actually
220
00:21:27,919 --> 00:21:34,730
it's are short on the on the power
221
00:21:32,240 --> 00:21:37,069
supply rail what what powers of what
222
00:21:34,730 --> 00:21:52,069
power realities is getting out from that
223
00:21:37,069 --> 00:21:54,918
MOSFET thus thus does the thing is the
224
00:21:52,069 --> 00:21:57,079
next to the the graphic chip so is very
225
00:21:54,919 --> 00:22:11,840
possible to be the the graphics power
226
00:21:57,079 --> 00:22:14,928
supply no no no no no you have to cause
227
00:22:11,839 --> 00:22:20,538
there on the left hand and on the right
228
00:22:14,929 --> 00:22:22,519
of the the two MOSFETs yeah why you know
229
00:22:20,538 --> 00:22:24,470
which on the other side of the board we
230
00:22:22,519 --> 00:22:52,970
have two more MOSFETs you can check on
231
00:22:24,470 --> 00:22:54,230
the other side of the board yes so
232
00:22:52,970 --> 00:22:56,829
actually there you have two power
233
00:22:54,230 --> 00:22:58,128
supplies that's why you have two coils
234
00:22:56,829 --> 00:23:01,509
yeah
235
00:22:58,128 --> 00:23:01,509
check those muscles for short
236
00:23:03,579 --> 00:23:09,939
so check each thing it's okay because
237
00:23:07,659 --> 00:23:13,869
our three pins with four pins so it's
238
00:23:09,940 --> 00:23:36,970
okay check the other one the other a
239
00:23:13,868 --> 00:23:41,939
MOSFET is beeping there yes yes one
240
00:23:36,970 --> 00:23:46,558
second does the one yeah so does beeping
241
00:23:41,940 --> 00:23:46,558
yes that's bad
242
00:23:48,058 --> 00:23:57,730
okay check with the ground please and on
243
00:23:55,808 --> 00:24:07,118
the other side of the MOSFET with a with
244
00:23:57,730 --> 00:24:21,548
the ground please yeah it's no beeping
245
00:24:07,118 --> 00:24:23,108
with the ground true or not okay help me
246
00:24:21,548 --> 00:24:27,308
with something you have two capacitor
247
00:24:23,108 --> 00:24:29,739
two ceramic capacitors there next C if C
248
00:24:27,308 --> 00:24:38,769
is beeping from the ceramic capacitor to
249
00:24:29,739 --> 00:24:42,179
the MOSFET pin please yeah okay that's
250
00:24:38,769 --> 00:24:42,179
our problem that Mossad
251
00:24:44,909 --> 00:24:56,049
so that MOSFET is insured is no beeping
252
00:24:54,339 --> 00:24:58,918
because it's a power supply you have two
253
00:24:56,048 --> 00:25:01,798
MOSFETs on the power supply yeah and
254
00:24:58,919 --> 00:25:05,139
like our own series serial mode and
255
00:25:01,798 --> 00:25:08,349
because this isn't short will get hot
256
00:25:05,138 --> 00:25:10,628
the second one you understand this is
257
00:25:08,349 --> 00:25:12,849
like a wire obviously this will not get
258
00:25:10,628 --> 00:25:16,699
art will get hot the second one which is
259
00:25:12,849 --> 00:25:19,608
good yeah
260
00:25:16,700 --> 00:25:21,409
good you have to check now because on
261
00:25:19,608 --> 00:25:24,980
these MOSFETs you can't make sure this
262
00:25:21,409 --> 00:25:29,480
is a power supply MOSFET check where is
263
00:25:24,980 --> 00:25:46,249
the you have a dot on the chip see what
264
00:25:29,480 --> 00:25:53,899
is the dot which yes which corner should
265
00:25:46,249 --> 00:25:58,399
be on a corner okay you have our own the
266
00:25:53,898 --> 00:26:00,878
board yes yeah okay let's take down that
267
00:25:58,398 --> 00:26:00,878
MOSFET
268
00:26:01,930 --> 00:26:05,048
[Music]
269
00:26:20,640 --> 00:26:28,620
oh I know that HP model that's a nice HP
270
00:26:25,140 --> 00:26:40,670
you have a graphic chip you have a good
271
00:26:28,619 --> 00:26:40,669
processor yeah it's i seven no it's not
272
00:26:42,079 --> 00:26:57,500
okay okay just just move the board a
273
00:26:55,740 --> 00:27:06,329
little bit to see it to having a picture
274
00:26:57,500 --> 00:27:11,400
the board okay that's great so now you
275
00:27:06,329 --> 00:27:17,428
can come with the hotel just go for how
276
00:27:11,400 --> 00:27:19,470
much you have there 450 450 and you know
277
00:27:17,429 --> 00:27:24,900
just grab that chip with a with a
278
00:27:19,470 --> 00:27:32,460
tweezer and you you don't have liquid
279
00:27:24,900 --> 00:27:34,259
flux here one second one second okay no
280
00:27:32,460 --> 00:27:36,808
that's a capacitor that big black one I
281
00:27:34,259 --> 00:27:42,048
was thinking it's a connector it's a
282
00:27:36,808 --> 00:27:42,048
connector or a capacitor that one yeah
283
00:27:44,419 --> 00:28:03,840
is no plastic here it's a cop it's a
284
00:27:51,660 --> 00:28:06,360
connector now it's a capacitor no it's
285
00:28:03,839 --> 00:28:08,668
okay don't worry don't worry you should
286
00:28:06,359 --> 00:28:10,529
you should just get concentrated you
287
00:28:08,669 --> 00:28:19,860
know to take that chip without moving
288
00:28:10,529 --> 00:28:23,178
nothing else you can try eventually
289
00:28:19,859 --> 00:28:29,990
eventually to push the chip up you know
290
00:28:23,179 --> 00:28:29,990
you know what I mean okay
291
00:28:32,750 --> 00:29:12,240
okay you can do it I'm sure so 450 yeah
292
00:29:03,210 --> 00:29:14,250
yeah butwe 450 you can play too much you
293
00:29:12,240 --> 00:29:18,349
know when it's the solder is melting you
294
00:29:14,250 --> 00:29:18,349
have to take out the chip yeah yeah
295
00:30:01,299 --> 00:30:06,009
now I just you know that's it has to
296
00:30:03,700 --> 00:30:20,620
move freely when it's moving freely you
297
00:30:06,009 --> 00:30:22,480
can pull it out yeah okay now you have
298
00:30:20,619 --> 00:30:50,199
to check that MOSFET with a multimeter
299
00:30:22,480 --> 00:30:55,420
to be sure it's insured so it is assured
300
00:30:50,200 --> 00:30:58,150
here okay okay let's double check yeah
301
00:30:55,420 --> 00:30:59,890
let's double check go back to it to the
302
00:30:58,150 --> 00:31:02,470
green resistor and come with a power
303
00:30:59,890 --> 00:31:17,200
supply we 19 volts to see if we have
304
00:31:02,470 --> 00:31:21,000
short anymore no no no on the other side
305
00:31:17,200 --> 00:31:21,000
on the other side on the green resistor
306
00:31:40,190 --> 00:31:58,330
no junior black to the ground yeah okay
307
00:31:59,470 --> 00:32:15,528
and on the power supply if it's still
308
00:32:06,980 --> 00:32:19,250
short I'll check on the power supply is
309
00:32:15,528 --> 00:32:22,159
19 and arms that's great that's
310
00:32:19,250 --> 00:32:30,109
fantastic that's all that's all yeah
311
00:32:22,159 --> 00:32:32,450
that's all just take all the wires no no
312
00:32:30,109 --> 00:32:34,939
no he's not taking arms you have to
313
00:32:32,450 --> 00:32:36,620
press the power button to take arms but
314
00:32:34,940 --> 00:32:38,538
we have to fix that power supply that's
315
00:32:36,619 --> 00:32:40,729
not like a passing MOSFET actually that
316
00:32:38,538 --> 00:32:44,450
most of it it is apart from a power
317
00:32:40,730 --> 00:32:48,230
supply if we check my video you know the
318
00:32:44,450 --> 00:32:50,538
path is two MOSFETs one coil and you
319
00:32:48,230 --> 00:32:52,370
know so we have to replace that MOSFET
320
00:32:50,538 --> 00:32:56,210
you still have the other board for
321
00:32:52,369 --> 00:32:58,788
spares that's fantastic you see we can
322
00:32:56,210 --> 00:33:01,778
take now the hopefully you have this
323
00:32:58,788 --> 00:33:01,778
small mosque as there
324
00:33:29,250 --> 00:33:35,950
so you see your first your first your
325
00:33:32,589 --> 00:33:40,509
first feeling was that MOSFET is faulty
326
00:33:35,950 --> 00:33:43,269
because it's getting hot yes you see you
327
00:33:40,509 --> 00:33:44,829
see and actually if you'll start placing
328
00:33:43,269 --> 00:33:46,720
you'll see you replace that with a
329
00:33:44,829 --> 00:33:49,269
different one and it's still getting hot
330
00:33:46,720 --> 00:33:51,069
and then you'll ask you why you know you
331
00:33:49,269 --> 00:33:53,829
will you ask yourself why
332
00:33:51,069 --> 00:33:56,470
but because the the the 19 was power L
333
00:33:53,829 --> 00:33:58,329
is not coming to that MOSFET actually is
334
00:33:56,470 --> 00:34:00,880
coming to this MOSFET which you took it
335
00:33:58,329 --> 00:34:03,779
out and from the output of that MOSFET
336
00:34:00,880 --> 00:34:10,090
is going on that one
337
00:34:03,779 --> 00:34:15,009
okay okay let leave on this side one
338
00:34:10,090 --> 00:34:19,600
second I can see you have some small
339
00:34:15,010 --> 00:34:21,669
most as they're good now you have to
340
00:34:19,599 --> 00:34:24,279
understand how you how you can identify
341
00:34:21,668 --> 00:34:26,469
the MOSFET it's okay we can use this
342
00:34:24,280 --> 00:34:30,019
MOSFET even if are not the same and we
343
00:34:26,469 --> 00:34:31,259
don't even care what most bizarre but
344
00:34:30,019 --> 00:34:34,929
[Music]
345
00:34:31,260 --> 00:34:37,540
exactly why the MOSFET who goes to the
346
00:34:34,929 --> 00:34:40,269
plus to the correct the capacitor that's
347
00:34:37,539 --> 00:34:43,509
our MOSFET not the one which is going
348
00:34:40,269 --> 00:34:48,009
with the pins on to the ground you
349
00:34:43,510 --> 00:34:51,010
understand so you have to check with a
350
00:34:48,010 --> 00:34:59,310
multimeter and find which one is going
351
00:34:51,010 --> 00:34:59,310
to the capacitor exactly
352
00:35:04,780 --> 00:35:12,480
so that's what uh with the paper mold as
353
00:35:07,599 --> 00:35:12,480
well yes okay
354
00:35:12,500 --> 00:35:15,619
[Music]
355
00:35:29,150 --> 00:35:38,789
so the the top one here the one
356
00:35:33,380 --> 00:35:48,390
okay the lower one that one is going to
357
00:35:38,789 --> 00:35:50,190
the capacitor okay okay now check with
358
00:35:48,389 --> 00:35:52,289
the ground let's double check with the
359
00:35:50,190 --> 00:36:02,880
ground and see which one is weaving with
360
00:35:52,289 --> 00:36:08,429
the ground the same one yeah but that's
361
00:36:02,880 --> 00:36:10,019
not good let's let's have a look for a
362
00:36:08,429 --> 00:36:18,449
different power supply because this is
363
00:36:10,019 --> 00:36:22,199
confusing on that one yeah but we we
364
00:36:18,449 --> 00:36:27,119
need a small MOSFETs now now we need to
365
00:36:22,199 --> 00:36:35,609
find the path to MOSFETs a coil go on
366
00:36:27,119 --> 00:36:44,699
the other side okay and MOSFET oh those
367
00:36:35,610 --> 00:36:57,050
MOSFETs are from the coil yeah okay one
368
00:36:44,699 --> 00:36:57,049
second how can we check how can I church
369
00:36:58,400 --> 00:37:04,470
yeah that's what I am thinking you know
370
00:37:01,670 --> 00:37:06,329
actually we need to you have to checked
371
00:37:04,469 --> 00:37:12,119
with the beeping with the 19 volts power
372
00:37:06,329 --> 00:37:18,960
L by DOE remember this board you have
373
00:37:12,119 --> 00:37:26,730
any idea what is the 19 volts what is
374
00:37:18,960 --> 00:37:28,710
the one second one second okay I
375
00:37:26,730 --> 00:37:31,440
remember this board yeah from the ship
376
00:37:28,710 --> 00:37:33,210
from the output from the area so you
377
00:37:31,440 --> 00:37:35,940
have to check from there check from
378
00:37:33,210 --> 00:37:38,460
there to the ground please see for so if
379
00:37:35,940 --> 00:37:39,780
we have short or not because if we have
380
00:37:38,460 --> 00:37:44,940
short it is
381
00:37:39,780 --> 00:37:50,310
it's hard to be checked what about
382
00:37:44,940 --> 00:37:52,440
another pin there is no short here okay
383
00:37:50,309 --> 00:37:56,360
from the other pin from the other pin
384
00:37:52,440 --> 00:37:59,639
yet the first one no no the first pin
385
00:37:56,360 --> 00:38:04,710
there on the on the back of the
386
00:37:59,639 --> 00:38:08,489
motherboard where are the MOSFETs I know
387
00:38:04,710 --> 00:38:16,289
it's it's it's it's it's hard but try to
388
00:38:08,489 --> 00:38:18,589
do it see you the SU on which MOSFET is
389
00:38:16,289 --> 00:38:18,590
going
390
00:38:33,179 --> 00:38:42,699
because we need one channel Channel and
391
00:38:39,219 --> 00:39:02,139
I think I think the Buddha Channel in
392
00:38:42,699 --> 00:39:07,568
any way or not I can't see but just keep
393
00:39:02,139 --> 00:39:15,518
in mind on which one you can show me on
394
00:39:07,568 --> 00:39:17,768
the board now that one yeah yeah okay
395
00:39:15,518 --> 00:39:22,199
that's great now take it out now because
396
00:39:17,768 --> 00:39:22,199
that's I was thinking it does the one
397
00:39:26,818 --> 00:39:33,489
should be a dot should be a dot check
398
00:39:29,768 --> 00:39:35,258
check carefully okay you know what you
399
00:39:33,489 --> 00:39:38,798
know what don't don't worry about the
400
00:39:35,259 --> 00:39:40,239
dot you know one side you have four pins
401
00:39:38,798 --> 00:39:47,048
together on the other side you have
402
00:39:40,239 --> 00:39:49,960
frame pins together yeah
403
00:39:47,048 --> 00:39:52,088
so that dot pad with four pins and three
404
00:39:49,960 --> 00:40:11,710
pins should match with your motherboard
405
00:39:52,088 --> 00:40:14,409
that's very important the pins okay very
406
00:40:11,710 --> 00:40:18,608
short are all all four together true or
407
00:40:14,409 --> 00:40:27,068
not and where is longer are 3 and plus
408
00:40:18,608 --> 00:40:30,818
one true okay you can take it out yeah
409
00:40:27,068 --> 00:40:33,159
so actually our four is like a plate are
410
00:40:30,818 --> 00:40:38,650
not pins so where are the short ones
411
00:40:33,159 --> 00:40:40,440
have note pins there is a plate so you
412
00:40:38,650 --> 00:40:48,530
can grab that most without
413
00:40:40,440 --> 00:40:48,530
okay same 450 use of flux
414
00:42:10,269 --> 00:42:13,929
no rush no rush
415
00:42:23,909 --> 00:42:28,989
you need a another a little bit bigger
416
00:42:26,800 --> 00:42:32,730
because the idea is to hit the board
417
00:42:28,989 --> 00:42:36,489
because the board will suck your heat
418
00:42:32,730 --> 00:42:40,869
you know what I mean in the future I
419
00:42:36,489 --> 00:42:43,529
mean use up just a little bit nozzle you
420
00:42:40,869 --> 00:42:43,530
know a bigger nozzle
421
00:43:17,710 --> 00:43:32,470
yeah so everything is fine yeah okay
422
00:43:24,760 --> 00:43:40,420
that's good that's good you can show me
423
00:43:32,469 --> 00:43:42,519
that MOSFET from the back yeah on the
424
00:43:40,420 --> 00:43:50,139
other side you see it's a play there are
425
00:43:42,519 --> 00:44:09,550
no pins it's a plate okay okay let's
426
00:43:50,139 --> 00:44:11,769
solder another worth so now it's very
427
00:44:09,550 --> 00:44:13,810
important to see the board where are all
428
00:44:11,769 --> 00:44:19,869
four pins together that place will be
429
00:44:13,809 --> 00:44:26,219
there they see the plate yeah should be
430
00:44:19,869 --> 00:44:26,219
where are all four pins together okay
431
00:44:38,519 --> 00:44:43,719
you can use flux the flux it's always
432
00:44:41,469 --> 00:44:45,099
good to be used so you can put now some
433
00:44:43,719 --> 00:44:49,469
flux and after that you can put the
434
00:44:45,099 --> 00:44:49,469
mosfet over you know
435
00:44:55,710 --> 00:45:00,139
just a little bit yeah that's all yeah
436
00:45:12,980 --> 00:45:21,269
you just put it now yeah you check the
437
00:45:17,039 --> 00:45:23,099
position yeah okay and you have to keep
438
00:45:21,269 --> 00:45:25,349
it down with with the tweezer because
439
00:45:23,099 --> 00:45:54,088
the hot air will blow blow the most
440
00:45:25,349 --> 00:45:57,030
without fifty yeah that's why it's okay
441
00:45:54,088 --> 00:46:00,659
for short time you know but if you like
442
00:45:57,030 --> 00:46:03,839
play there minutes the will be bad for
443
00:46:00,659 --> 00:46:07,549
the board but just for replacing a
444
00:46:03,838 --> 00:46:07,549
MOSFET quickly that that's okay
445
00:46:37,730 --> 00:46:42,588
yeah leave it there and try and want to
446
00:46:40,250 --> 00:46:51,019
move it on the position with the tweezer
447
00:46:42,588 --> 00:46:53,798
if it's not on the position and all the
448
00:46:51,019 --> 00:46:53,798
pins are sore Lord
449
00:47:16,369 --> 00:47:28,700
that ship you know she'll move like
450
00:47:18,349 --> 00:47:30,349
freely when the solder is melt you don't
451
00:47:28,699 --> 00:47:32,960
have to push just try to move it around
452
00:47:30,349 --> 00:47:35,499
like just a little bit just a little
453
00:47:32,960 --> 00:47:35,499
touch
454
00:47:44,420 --> 00:47:53,610
see it's okay if I think it's okay it's
455
00:47:47,940 --> 00:47:57,349
okay so just cool down the area and
456
00:47:53,610 --> 00:47:57,349
let's check to see if it's working on
457
00:48:05,449 --> 00:48:12,329
[Music]
458
00:48:09,199 --> 00:48:14,909
which side the important is the gate pin
459
00:48:12,329 --> 00:48:25,559
to be soldered and to be like not
460
00:48:14,909 --> 00:48:27,000
shorted with other ones yeah don't worry
461
00:48:25,559 --> 00:48:31,079
about the play side don't worry there
462
00:48:27,000 --> 00:48:33,510
about that side okay
463
00:48:31,079 --> 00:48:45,989
okay well let's check plug the charger
464
00:48:33,510 --> 00:48:50,240
and see what's happened the thermal pads
465
00:48:45,989 --> 00:48:50,239
yeah you need one you need one
466
00:49:55,559 --> 00:50:07,119
you should get a light isn't it yes well
467
00:50:00,809 --> 00:50:12,000
we don't know okay let's check the 19
468
00:50:07,119 --> 00:50:12,000
volts on the green resistor
469
00:50:56,230 --> 00:51:03,409
nothing okay take all the charger and
470
00:51:01,969 --> 00:51:14,929
let's come with the power supply in this
471
00:51:03,409 --> 00:51:18,710
case we have it's on the green register
472
00:51:14,929 --> 00:51:19,480
is 19 volt yes okay that's good that's
473
00:51:18,710 --> 00:51:33,889
good
474
00:51:19,480 --> 00:51:37,219
you have the power button there okay
475
00:51:33,889 --> 00:51:40,179
check with the multimeter see if we have
476
00:51:37,219 --> 00:51:40,179
3.3 volts
477
00:51:56,369 --> 00:52:08,309
goodsoon 16 what's there no idea you can
478
00:52:06,778 --> 00:52:11,730
take down the power button and put the
479
00:52:08,309 --> 00:52:17,539
power button there I don't know if if if
480
00:52:11,730 --> 00:52:17,539
we sure that pins it will come on
481
00:52:26,400 --> 00:52:37,170
yeah there's not 3.3 okay let's try to
482
00:52:31,659 --> 00:52:37,170
see you have the power button there
483
00:53:07,838 --> 00:53:19,190
no nothing nothing yeah okay do you see
484
00:53:14,960 --> 00:53:23,199
like bioship there because I'm looking
485
00:53:19,190 --> 00:53:23,200
for a biochip I can't see a boy's ship
486
00:53:28,088 --> 00:53:59,809
which one is does the - your startup
487
00:53:43,909 --> 00:54:01,789
ship here but what about the bioship the
488
00:53:59,809 --> 00:54:05,179
the black one from the other side is the
489
00:54:01,789 --> 00:54:07,759
buyer ship on the opposite side of that
490
00:54:05,179 --> 00:54:12,949
ship on this here here here here here on
491
00:54:07,760 --> 00:54:15,760
this side of the board yeah on the back
492
00:54:12,949 --> 00:54:18,679
of that ship you see that ship this ship
493
00:54:15,760 --> 00:54:23,450
which you know what is the charging
494
00:54:18,679 --> 00:54:27,108
connector up up up up up it's a black
495
00:54:23,449 --> 00:54:31,250
ship there yeah okay what is writing on
496
00:54:27,108 --> 00:54:33,460
that ship what is saying or not you you
497
00:54:31,250 --> 00:54:33,460
sure
498
00:54:42,110 --> 00:54:45,189
[Music]
499
00:54:58,480 --> 00:55:10,639
but you can see exactly what numbers and
500
00:55:01,250 --> 00:55:27,519
what is writing there because we have to
501
00:55:10,639 --> 00:55:27,519
find a 3.3 volts power supply mxc I see
502
00:55:27,639 --> 00:55:36,068
25 25 well I think that about ship yeah
503
00:55:39,099 --> 00:55:48,829
okay you can see the pin number 8 from
504
00:55:41,630 --> 00:55:50,869
that chip pin number 8 yes okay so with
505
00:55:48,829 --> 00:55:53,839
the multimeter yeah I have to keep one
506
00:55:50,869 --> 00:55:56,539
probe on on the pin number 8 and with
507
00:55:53,838 --> 00:56:01,449
other probe to go on all over the Colo
508
00:55:56,539 --> 00:56:01,449
all the coils and check for beeping
509
00:56:01,568 --> 00:56:06,460
first check from the pin number a to
510
00:56:04,010 --> 00:56:06,460
ground
511
00:56:23,960 --> 00:56:31,970
it's not short here okay now go to all
512
00:56:27,679 --> 00:56:37,460
on the coils yeah coils coils no no no
513
00:56:31,969 --> 00:56:40,489
capacitor Queens no no on the coils yeah
514
00:56:37,460 --> 00:56:42,619
yeah yeah and see which one is beeping
515
00:56:40,489 --> 00:56:44,838
no it's one pin it's okay you don't have
516
00:56:42,619 --> 00:56:51,140
to check on the on the both sides of the
517
00:56:44,838 --> 00:56:59,920
coil what about under the the the RAM
518
00:56:51,139 --> 00:56:59,920
memory slot there you have some quads
519
00:57:00,670 --> 00:57:04,579
nothing
520
00:57:01,849 --> 00:57:08,318
okay what about on the on the top of the
521
00:57:04,579 --> 00:57:15,109
board top top top you have a coil there
522
00:57:08,318 --> 00:57:19,750
nothing okay one second let me check go
523
00:57:15,108 --> 00:57:19,750
down where I was that MOSFET getting hot
524
00:57:22,480 --> 00:57:32,568
yeah and check on the board coils so
525
00:57:27,619 --> 00:57:34,910
it's beeping he's beeping which one I
526
00:57:32,568 --> 00:57:44,949
can't see just tell me which one is the
527
00:57:34,909 --> 00:57:47,949
next two days decorator order one second
528
00:57:44,949 --> 00:57:55,129
so that's the 3.3 volts power supply
529
00:57:47,949 --> 00:57:59,419
yeah okay okay now from that coil go to
530
00:57:55,130 --> 00:58:12,650
the those MOSFET and see which is
531
00:57:59,420 --> 00:58:14,980
beeping from the quail what about on a
532
00:58:12,650 --> 00:58:14,980
big one
533
00:58:18,440 --> 00:58:24,950
nothing no okay now I have to I want to
534
00:58:23,059 --> 00:58:28,389
keep that thing on the coil and go on
535
00:58:24,949 --> 00:58:28,389
the other side of the board and check
536
00:58:28,750 --> 00:58:47,500
yeah keep on the coil yeah
537
00:58:44,500 --> 00:59:00,219
so what is beeping under under our
538
00:58:47,500 --> 00:59:03,818
MOSFET is no beeping on our MOSFET here
539
00:59:00,219 --> 00:59:03,818
on which one
540
00:59:19,500 --> 00:59:28,829
no no beeping at all don't see any
541
00:59:26,860 --> 00:59:33,880
others
542
00:59:28,829 --> 00:59:38,130
okay the turn around the board because
543
00:59:33,880 --> 00:59:38,130
there shall be a MOSFET a second MOSFET
544
00:59:51,699 --> 01:00:37,460
except beeping on that it's just there
545
01:00:29,570 --> 01:00:56,269
and on another yeah on the big one is
546
01:00:37,460 --> 01:00:58,550
not going so it should be a check on the
547
01:00:56,269 --> 01:01:01,429
other side again please Rico should be a
548
01:00:58,550 --> 01:01:04,000
second MOSFET you know it does how these
549
01:01:01,429 --> 01:01:04,000
things work
550
01:02:06,298 --> 01:02:28,170
I found it
551
01:02:12,539 --> 01:02:32,839
okay which one is so this one I can't
552
01:02:28,170 --> 01:02:32,838
see so the one which you you replace it
553
01:02:34,139 --> 01:02:44,548
we're next
554
01:02:37,199 --> 01:02:51,209
does the one yeah we replaced okay turn
555
01:02:44,548 --> 01:02:54,498
around the board okay set up the power
556
01:02:51,208 --> 01:02:54,498
supply on 3.3 volt
557
01:03:30,559 --> 01:03:36,929
three point three okay and comma ground
558
01:03:34,889 --> 01:03:39,409
to the ground and plus to the coil to
559
01:03:36,929 --> 01:03:39,409
that quail
560
01:03:57,918 --> 01:04:02,148
so what do we have on the power supply
561
01:04:07,009 --> 01:04:13,219
in Viet Nam's
562
01:04:09,329 --> 01:04:30,268
[Music]
563
01:04:13,219 --> 01:04:31,918
0.20 200 millions 0.02 or 0.2 zero okay
564
01:04:30,268 --> 01:04:41,668
that's not good you have to keep there
565
01:04:31,918 --> 01:04:44,098
and check what is getting hot go to the
566
01:04:41,668 --> 01:04:49,888
the startup ship see if the startup ship
567
01:04:44,099 --> 01:04:52,429
is getting hot the big ship you know you
568
01:04:49,889 --> 01:04:52,429
know which one
569
01:05:18,199 --> 01:05:20,949
No
570
01:05:23,838 --> 01:05:30,440
something else should get warm warm no
571
01:05:26,818 --> 01:05:30,440
heart no heart worm
572
01:05:59,869 --> 01:06:09,130
what about the big chip now that one
573
01:06:07,009 --> 01:06:12,130
that one that one yeah
574
01:06:09,130 --> 01:06:12,130
No
575
01:06:23,849 --> 01:06:31,318
you have to check even on the other side
576
01:06:25,768 --> 01:06:34,639
of the board yeah well they're all I
577
01:06:31,318 --> 01:06:34,639
don't know how you you can do it
578
01:06:46,400 --> 01:06:50,450
you know what plug the charger connector
579
01:06:48,739 --> 01:06:54,349
and see if you have light when you put
580
01:06:50,449 --> 01:06:58,579
voltage there but without a charger you
581
01:06:54,349 --> 01:07:02,960
just take out the charger unplug the
582
01:06:58,579 --> 01:07:05,059
charger here okay that's good and plug
583
01:07:02,960 --> 01:07:09,159
the connector and see if you have light
584
01:07:05,059 --> 01:07:09,159
when you when you use three-point Frieda
585
01:07:13,329 --> 01:07:18,789
Yahweh is not connected the connector is
586
01:07:15,530 --> 01:07:18,790
not connect is not connected
587
01:08:05,250 --> 01:08:20,699
you have light no you should be on the
588
01:08:12,670 --> 01:08:20,699
charger isn't it yeah no no okay okay
589
01:08:21,180 --> 01:08:33,789
plug the charger now take out take out
590
01:08:25,810 --> 01:08:41,530
the or keep it and plug the charger how
591
01:08:33,789 --> 01:08:42,729
do you wish and put now free point free
592
01:08:41,529 --> 01:08:44,909
and see if you get the light on the
593
01:08:42,729 --> 01:08:44,909
charger
594
01:08:57,670 --> 01:09:10,029
no no like okay okay check with a
595
01:09:07,659 --> 01:09:11,949
multimeter with our own volts yeah now
596
01:09:10,029 --> 01:09:16,679
when the charger is plugged what voltage
597
01:09:11,949 --> 01:09:16,679
do you have there on that coil
598
01:09:34,279 --> 01:09:58,670
yeah well pretty much nothing 0.70 what
599
01:09:52,548 --> 01:10:07,390
about on the MOSFET on the small line on
600
01:09:58,670 --> 01:10:07,390
the other side okay turn around the Borg
601
01:10:07,420 --> 01:10:22,640
let's check on the other side okay just
602
01:10:20,119 --> 01:10:26,109
move the board a little bit to see you
603
01:10:22,640 --> 01:10:26,110
having a picture yeah there yeah
604
01:10:27,430 --> 01:10:33,460
and check now with a multimeter for
605
01:10:29,869 --> 01:10:33,460
voltage yeah yeah
606
01:10:41,880 --> 01:10:55,140
how many how much how many balls we have
607
01:10:43,979 --> 01:11:02,849
there okay nineteen okay on the other
608
01:10:55,140 --> 01:11:10,680
side okay what about on the most part
609
01:11:02,850 --> 01:11:14,840
what do you replace it on the plate side
610
01:11:10,680 --> 01:11:14,840
but III want to know on the play side
611
01:11:15,409 --> 01:11:43,710
and on the other side on the gate check
612
01:11:25,680 --> 01:11:46,289
on the gate okay okay now the things get
613
01:11:43,710 --> 01:11:49,560
most more complicated you have to you
614
01:11:46,289 --> 01:11:52,109
must have a chip there check if you see
615
01:11:49,560 --> 01:11:58,590
you have achieved down down next to the
616
01:11:52,109 --> 01:12:01,099
hole yeah there one second that chip is
617
01:11:58,590 --> 01:12:01,100
getting hot
618
01:12:14,949 --> 01:12:19,809
okay you have to check that shape here
619
01:12:22,840 --> 01:12:35,690
okay okay take out the voltage take out
620
01:12:27,380 --> 01:12:39,380
the the yeah and now check yeah check on
621
01:12:35,689 --> 01:12:45,109
the MOSFET what we replace it yeah with
622
01:12:39,380 --> 01:12:46,690
the beeping thing yeah all those pins
623
01:12:45,109 --> 01:12:49,369
from the other side
624
01:12:46,689 --> 01:12:51,529
check with the gate I just want to know
625
01:12:49,369 --> 01:13:01,340
if the gate is short with the shorted
626
01:12:51,529 --> 01:13:03,880
with other pins there yeah you see
627
01:13:01,340 --> 01:13:03,880
that's the problem
628
01:13:03,909 --> 01:13:22,340
okay let's you don't have a bigger
629
01:13:06,859 --> 01:13:24,559
nozzle so you understand how these
630
01:13:22,340 --> 01:13:48,380
things were that chip is driving the all
631
01:13:24,560 --> 01:13:51,910
four MOSFETs just you show me I think
632
01:13:48,380 --> 01:13:51,909
it's perfect use that one
633
01:13:56,010 --> 01:14:03,720
so a little bit and try to get basically
634
01:14:00,939 --> 01:14:07,109
yeah yeah
635
01:14:03,720 --> 01:14:10,720
hopefully the hopefully that the cheaper
636
01:14:07,109 --> 01:14:19,829
but no no it's impossible I don't think
637
01:14:10,720 --> 01:14:19,829
that she died okay okay
638
01:14:26,399 --> 01:14:29,909
nephew some flocks
639
01:16:16,539 --> 01:16:23,180
you took out the the the charger yeah
640
01:16:21,010 --> 01:16:25,840
yeah yeah okay
641
01:16:23,180 --> 01:16:25,840
that's good that's good
642
01:16:53,979 --> 01:17:03,389
just move the board a little bit left
643
01:16:57,029 --> 01:17:03,389
the right sorry yeah thank you yeah
644
01:17:52,420 --> 01:18:00,970
if you keep the tweezer on the chip
645
01:17:54,729 --> 01:18:03,099
you'll suck the heat from the ship just
646
01:18:00,970 --> 01:18:04,570
try to tease it and see when it's moving
647
01:18:03,100 --> 01:18:17,410
and when it's moving actually you can
648
01:18:04,569 --> 01:18:23,880
pull it out okay oh you see you see we
649
01:18:17,409 --> 01:18:23,880
are getting the check for short yeah
650
01:18:40,430 --> 01:18:48,770
no it's ok if it's ok solder back the
651
01:18:46,560 --> 01:18:48,770
chip
652
01:19:48,078 --> 01:19:54,349
so you understand just keep keep that
653
01:19:50,868 --> 01:19:55,939
cheap yeah and use the hot air when you
654
01:19:54,349 --> 01:19:58,069
see the soul that is melting just
655
01:19:55,939 --> 01:20:00,649
release the the tweezer and leave the
656
01:19:58,069 --> 01:20:02,630
cheap to like the get just sit by itself
657
01:20:00,649 --> 01:20:04,969
you know without pushing because when
658
01:20:02,630 --> 01:20:07,849
you push the cheap down the solder from
659
01:20:04,969 --> 01:20:30,380
behind will pop out and I'll make sure
660
01:20:07,849 --> 01:20:38,210
to everywhere you know what I mean you
661
01:20:30,380 --> 01:20:41,139
sure the position is okay yeah okay yeah
662
01:20:38,210 --> 01:20:41,139
I believe you believe you
663
01:21:11,409 --> 01:21:25,930
oh just use the hotel more and you know
664
01:21:23,590 --> 01:21:29,970
just just touch touch the chip with the
665
01:21:25,930 --> 01:21:29,970
tweezer and see if it's moving freely
666
01:21:41,109 --> 01:21:50,368
it is yeah okay so if you solve that
667
01:21:44,979 --> 01:21:50,368
here it's okay if you think it's older
668
01:21:54,029 --> 01:22:02,649
it's all that okay that's great that's
669
01:21:59,770 --> 01:22:04,420
good just I want to check for short you
670
01:22:02,649 --> 01:22:50,578
know we draw without pain with a gate
671
01:22:04,420 --> 01:22:53,380
pin it is still short yeah
672
01:22:50,578 --> 01:22:55,058
boy you sure does the gate because that
673
01:22:53,380 --> 01:23:06,789
pin should be like separate from the
674
01:22:55,059 --> 01:23:09,909
others yeah I don't know if there is the
675
01:23:06,789 --> 01:23:13,868
gate I don't know if it's where is the
676
01:23:09,908 --> 01:23:15,670
dot but check all four pins compare with
677
01:23:13,868 --> 01:23:18,960
the next one yeah so check it for sure
678
01:23:15,670 --> 01:23:24,059
and see if you should have free together
679
01:23:18,960 --> 01:23:24,059
like short and one without
680
01:23:34,659 --> 01:23:42,800
so it's not the one I was with with the
681
01:23:38,569 --> 01:23:54,319
arrow shows not necessary okay I thought
682
01:23:42,800 --> 01:23:56,869
is that too much rocks in it so you
683
01:23:54,319 --> 01:24:00,579
shall not have all four pins together
684
01:23:56,869 --> 01:24:00,579
you should have only three together
685
01:24:55,300 --> 01:25:03,140
yeah well it still is beeping all four
686
01:24:59,390 --> 01:25:05,329
together that's what I asked you just
687
01:25:03,140 --> 01:25:07,039
keep the probe on one pin and check with
688
01:25:05,329 --> 01:25:10,300
the beeping with the other one for each
689
01:25:07,039 --> 01:25:10,300
pin and see if it's beeping
690
01:25:46,868 --> 01:25:52,279
you can clean it with a toothbrush in
691
01:25:49,368 --> 01:25:56,420
alcohol or petrol
692
01:25:52,279 --> 01:25:56,420
[Music]
693
01:26:51,639 --> 01:26:55,510
looks completely fine
694
01:27:16,578 --> 01:27:28,259
yeah it's all for the the first and the
695
01:27:25,920 --> 01:27:37,230
last one is beeping you can check the
696
01:27:28,260 --> 01:27:38,998
first and the last one from the gate to
697
01:27:37,229 --> 01:27:45,348
the other if one dough on the head on
698
01:27:38,998 --> 01:27:45,349
the sides on the sides of the chip sides
699
01:27:46,639 --> 01:27:55,559
the first pin and the last pin see if is
700
01:27:49,109 --> 01:27:58,189
beeping together yeah that's bad let's
701
01:27:55,559 --> 01:27:58,190
take those the chip
702
01:28:20,340 --> 01:28:25,500
same way just you tease the the cheap
703
01:28:23,340 --> 01:28:27,500
with the with the tweezer and when it's
704
01:28:25,500 --> 01:28:30,500
moving freely you can pull it out here
705
01:28:27,500 --> 01:28:30,500
yeah
706
01:28:55,680 --> 01:29:02,039
okay okay now clean the board with the
707
01:28:59,369 --> 01:29:05,779
petrol and I want to see the board you
708
01:29:02,039 --> 01:29:05,779
know if you can bring the board closer
709
01:29:42,760 --> 01:30:03,619
okay okay say you see oh there you have
710
01:30:01,130 --> 01:30:06,980
four pins yeah three are together one is
711
01:30:03,618 --> 01:30:08,719
not and one is not is the gate so if you
712
01:30:06,979 --> 01:30:11,388
check now the pin number where is the
713
01:30:08,719 --> 01:30:12,980
arrow yep that pin the pin number one
714
01:30:11,389 --> 01:30:16,400
and with the last pin
715
01:30:12,979 --> 01:30:20,209
yeah with P number four which that shall
716
01:30:16,399 --> 01:30:40,058
not be pin should not be beeping yeah so
717
01:30:20,210 --> 01:30:44,559
check now with the multimeter is beeping
718
01:30:40,059 --> 01:30:48,260
how many homes do you have check again
719
01:30:44,559 --> 01:30:51,099
or switch switch on ohms and tell me how
720
01:30:48,260 --> 01:30:51,099
many ones do you have
721
01:31:16,639 --> 01:31:29,029
I can't see just tell me how many how
722
01:31:17,988 --> 01:31:41,479
many rooms do you have how much is
723
01:31:29,029 --> 01:31:45,670
saying there twenty-eight okay switch
724
01:31:41,479 --> 01:31:45,669
the multimeter on two hundred ohms scale
725
01:31:50,109 --> 01:31:53,109
yeah
726
01:31:56,738 --> 01:32:13,939
how many ohms 1.5 yeah that's bad that's
727
01:32:04,039 --> 01:32:16,698
bad because because that pin is coming
728
01:32:13,939 --> 01:32:21,198
from that ship that ship is the five
729
01:32:16,698 --> 01:32:28,359
volts a 3.3 volts power supply and
730
01:32:21,198 --> 01:32:28,359
actually your 5 volts power supply died
731
01:32:29,800 --> 01:32:39,550
but they kill the chip so actually you
732
01:32:32,569 --> 01:32:44,868
don't have 3.3 they're also that chip
733
01:32:39,550 --> 01:32:48,130
yes tell me the name of that chip yeah
734
01:32:44,868 --> 01:33:04,039
that's the one from the bottom
735
01:32:48,130 --> 01:33:05,539
yeah yeah she'll be like I CL is oh you
736
01:33:04,039 --> 01:33:07,810
don't have a magnifying glass or
737
01:33:05,539 --> 01:33:07,810
something
738
01:33:16,850 --> 01:33:21,289
[Music]
739
01:33:31,069 --> 01:33:48,949
okay maybe now see try to change the
740
01:33:47,208 --> 01:33:53,118
board angle maybe you can see from
741
01:33:48,948 --> 01:34:30,608
different angle that's very important to
742
01:33:53,118 --> 01:34:30,608
know what chip is there okay
743
01:34:35,750 --> 01:34:57,140
so it's e w e eg 50 you're sure
744
01:34:51,460 --> 01:35:02,470
well if it's this one yeah that's the
745
01:34:57,140 --> 01:35:08,440
one yeah yeah so one more time
746
01:35:02,470 --> 01:35:08,440
so E one second one second
747
01:35:20,729 --> 01:35:47,059
II II from from elephant yeah let's try
748
01:35:36,929 --> 01:35:47,059
W then we ask one second one second
749
01:35:48,529 --> 01:36:05,300
Efram elephant here yeah okay
750
01:35:52,019 --> 01:36:12,090
and so w e8 w fe yeah okay and then is e
751
01:36:05,300 --> 01:36:14,630
50 I don't think we can find something
752
01:36:12,090 --> 01:36:14,630
like that
753
01:36:32,399 --> 01:36:47,789
so ii w as e f e from india here no
754
01:36:40,989 --> 01:36:47,789
Efram elephant yeah yeah 15 yeah
755
01:36:48,420 --> 01:36:52,829
no it's nothing like that online you
756
01:36:58,350 --> 01:37:09,030
sure does the name well that's what can
757
01:37:03,789 --> 01:37:09,029
i see that there's nothing else there
758
01:37:28,270 --> 01:37:37,909
okay let's go again back to the
759
01:37:30,920 --> 01:37:41,029
multimeter and switch on the dad mode on
760
01:37:37,908 --> 01:37:42,348
the beeping mode here and tell me again
761
01:37:41,029 --> 01:37:54,649
how much how many rooms do you have
762
01:37:42,349 --> 01:38:03,289
there from the first point the P number
763
01:37:54,649 --> 01:38:24,289
one and the pin number for a short is
764
01:38:03,289 --> 01:38:31,939
completely shorter so it's nothing what
765
01:38:24,289 --> 01:38:34,578
you can do you need that chip let me
766
01:38:31,939 --> 01:38:37,118
check on ebay anything we can't find
767
01:38:34,578 --> 01:38:37,118
anyway
768
01:38:49,849 --> 01:38:59,279
no nothing on anyway so yeah you know
769
01:38:56,340 --> 01:39:06,179
when you do just get that kind of bored
770
01:38:59,279 --> 01:39:07,710
yeah I don't have that cheap if I will
771
01:39:06,179 --> 01:39:09,288
have that cheap I'll send you that cheap
772
01:39:07,710 --> 01:39:15,719
but I don't have that board
773
01:39:09,288 --> 01:39:18,139
yes no I have boards there but not like
774
01:39:15,719 --> 01:39:18,139
this one
775
01:39:21,270 --> 01:39:25,880
probably this ship you can find it only
776
01:39:22,979 --> 01:39:25,879
on this board
777
01:39:39,250 --> 01:39:47,319
maybe you can find a faulty board well
778
01:39:45,250 --> 01:39:51,069
you know what I will check tomorrow I'll
779
01:39:47,319 --> 01:39:56,979
check on different boards we're sure
780
01:39:51,069 --> 01:40:02,789
does the name try more you know try to
781
01:39:56,979 --> 01:40:02,789
you I don't know without you know that
782
01:40:03,090 --> 01:40:09,190
ear but and clean that cheap and and
783
01:40:06,310 --> 01:40:15,370
then try to try to be sure about it what
784
01:40:09,189 --> 01:40:34,479
what is writing on that ship I'll send
785
01:40:15,369 --> 01:40:38,439
you yeah so ii w d s e15 sure does the
786
01:40:34,479 --> 01:40:41,769
name it might be the second one because
787
01:40:38,439 --> 01:40:47,619
that one because that one is like a
788
01:40:41,770 --> 01:40:49,870
little bit scratched or something it
789
01:40:47,619 --> 01:40:54,659
looks like that one it might be m oh
790
01:40:49,869 --> 01:40:54,659
it's a but everything else is the same
791
01:40:57,210 --> 01:41:09,750
so ii fy15
792
01:41:33,448 --> 01:41:37,579
nothing
793
01:41:34,479 --> 01:41:37,579
[Music]
794
01:41:57,369 --> 01:42:12,369
yeah well that's it there's nothing else
795
01:41:59,890 --> 01:42:21,310
and maybe it's not that chair he's not
796
01:42:12,369 --> 01:42:23,800
worth the chip maybe it's not no it
797
01:42:21,310 --> 01:42:25,600
should be together yeah yeah it's one
798
01:42:23,800 --> 01:42:33,610
chief for the board power supply so the
799
01:42:25,600 --> 01:42:40,390
nearest chip is that one well let me
800
01:42:33,609 --> 01:42:43,349
have a look on the board's the other
801
01:42:40,390 --> 01:42:50,550
side of the board you have nothing now
802
01:42:43,350 --> 01:42:50,550
and there you have only one chip
803
01:42:52,260 --> 01:42:57,989
you can check something more yeah to be
804
01:42:55,539 --> 01:43:00,909
sure that's our chip here
805
01:42:57,989 --> 01:43:09,579
go back you can switch the camera on the
806
01:43:00,909 --> 01:43:15,130
on the board yeah okay you have the
807
01:43:09,579 --> 01:43:17,289
other MOSFET the 3.31 yeah check on the
808
01:43:15,130 --> 01:43:19,529
P number one and number four C check for
809
01:43:17,289 --> 01:43:19,529
short
810
01:43:25,369 --> 01:43:30,079
all right yeah
811
01:43:40,189 --> 01:43:45,199
okay but you can see which is the pin
812
01:43:41,779 --> 01:43:48,819
number one with the gate or the gate is
813
01:43:45,199 --> 01:43:51,889
the pin or just try to find the gate pin
814
01:43:48,819 --> 01:44:00,409
the gaping shall not be beeping we know
815
01:43:51,890 --> 01:44:03,490
what we need we know one yeah that's
816
01:44:00,409 --> 01:44:07,010
separate here keep the probe there and
817
01:44:03,489 --> 01:44:14,689
with the other probe check on that chip
818
01:44:07,010 --> 01:44:17,510
and see if is beeping so you see that
819
01:44:14,689 --> 01:44:19,429
chip the gate go on that chip does mean
820
01:44:17,510 --> 01:44:28,730
even the other gates will go on same
821
01:44:19,430 --> 01:44:30,380
chip the other ship should go there you
822
01:44:28,729 --> 01:44:31,939
don't know maybe it's ground you don't
823
01:44:30,380 --> 01:44:33,529
know you have to take down the chip to
824
01:44:31,939 --> 01:44:35,989
see if exactly the way is going there
825
01:44:33,529 --> 01:44:38,899
don't worry about that your problem is
826
01:44:35,989 --> 01:44:41,029
the chip does the chip does that that
827
01:44:38,899 --> 01:44:43,369
chip handle to power supply three point
828
01:44:41,029 --> 01:44:46,189
three and five volts I think five volts
829
01:44:43,369 --> 01:44:49,569
but also can be a different voltage well
830
01:44:46,189 --> 01:44:53,449
anyway your that shorted MOSFET here
831
01:44:49,569 --> 01:44:57,109
bring probably 19 volts to the gate and
832
01:44:53,449 --> 01:45:00,949
kill that ship because the chip was
833
01:44:57,109 --> 01:45:03,829
shorted you know the MOSFET which we
834
01:45:00,949 --> 01:45:10,729
took it down doesn't mean that MOSFET
835
01:45:03,829 --> 01:45:12,890
pass 19 volts and probably that the the
836
01:45:10,729 --> 01:45:15,279
the 19 volts come on the gate and kill
837
01:45:12,890 --> 01:45:15,280
the chip
838
01:45:23,899 --> 01:45:29,629
try to don't don't just keep the board
839
01:45:26,779 --> 01:45:31,369
safe and try to find another board for
840
01:45:29,630 --> 01:45:36,159
space or just give me some time to know
841
01:45:31,369 --> 01:45:39,019
more and I'll check tomorrow yeah
842
01:45:36,159 --> 01:45:49,069
because I'm sure you need only that ship
843
01:45:39,020 --> 01:45:50,900
and that board will work okay yeah so
844
01:45:49,069 --> 01:45:54,789
that's our problem because he's short on
845
01:45:50,899 --> 01:45:54,789
the gate obviously is no signal they're
846
01:45:58,569 --> 01:46:08,750
good okay it's okay but you learn now
847
01:46:04,670 --> 01:46:29,779
you know how almost starting the
848
01:46:08,750 --> 01:46:31,520
diagnosing and things yeah okay what
849
01:46:29,779 --> 01:46:43,880
about on the other board another board
850
01:46:31,520 --> 01:46:49,790
you don't have this ship really I think
851
01:46:43,880 --> 01:46:51,109
so but you worth to check because
852
01:46:49,789 --> 01:46:57,649
usually are more cheese like that
853
01:46:51,109 --> 01:46:59,659
probably two free chips on each board so
854
01:46:57,649 --> 01:47:02,649
you can have the same chip on different
855
01:46:59,659 --> 01:47:02,649
power supplies
856
01:47:02,920 --> 01:47:06,369
what's the check
857
01:47:22,118 --> 01:47:31,198
now these are even different sizes yeah
858
01:47:52,079 --> 01:47:58,059
what about it that cheap you know from
859
01:47:55,529 --> 01:48:03,448
near from what he took out the MOSFET
860
01:47:58,060 --> 01:48:07,260
you know where to cut the MOSFET yeah
861
01:48:03,448 --> 01:48:09,210
yeah next it's a it's a chip there yeah
862
01:48:07,260 --> 01:48:22,360
what about that one
863
01:48:09,210 --> 01:48:26,289
it's not the same is different I'll have
864
01:48:22,359 --> 01:48:30,250
a look tomorrow yeah eventually can send
865
01:48:26,289 --> 01:48:34,539
me a no Facebook as the Skype is not
866
01:48:30,250 --> 01:48:46,658
working on the on the iPhone same email
867
01:48:34,539 --> 01:48:50,979
yeah and imagine yeah okay yes but
868
01:48:46,658 --> 01:49:06,009
tomorrow yeah okay so have a nice
869
01:48:50,979 --> 01:49:09,149
evening okay see you see you next time
870
01:49:06,010 --> 01:49:09,150
