Original subtitles

it's okay now yeah okay yeah okay

receive the pictures of the motherboard

boy is like low resolution it's not

loaded solution but it's not very good

so what is the problem you wanted to get

them closer no it's okay just just tell

me what do you check and what do we have

there she know yet yes and I have the

picture here yeah okay so yeah yes okay

let me grab the other picture one second

okay okay so you found the four but you

know what

oh and this you see how is the picture

now yeah how is the motherboard now yeah

let's plug the charger and let's check

together some voltages on

more yeah that's good okay yeah he's not

a point you know checking for the first

on MOSFETs if we have 19 volts on the

board charger all right yeah that's

great so check the voltage is the

voltage on the connector on the charging

charger connector there yeah that's

great you know on the other side yeah

you have the let me see whatever we can

check for now I want to check the 19

first and I'm just looking for a power

supply and those capacitors okay you are

there sorry one second let me change the

picture one second

okay you see where is the processor

socket there okay

under the processor socket yeah you have

some capacitors there there exactly

there no no no no where you put the

finger first time down there check with

the mood yeah that capacitor check with

the multimeter the voltage there okay on

the other side okay go up to the other

capacitors once it's not about ooh too

much there check there please okay dokay

okay

I was thinking of the processor one so

we don't have 19 volts there true or not

okay take out the the charging port

connector and let's check together let's

let's start from the charging port and

let's follow the 19 volts power okay

that's good now let's go on the on the

on the connector on the charger charger

connector there yeah yes and now switch

the the multimeter on the diode mode on

the beeping mode you see that read the

thing now let's find the first MOSFET

where is the first MOSFET yeah you can

take it away yeah yeah yeah I can see

well obviously you understand I can't

see what you see so you have to go from

the the plus yeah

and go on the MOSFETs and see which

MOSFET the voltage is going doesn't

matter know if that's it's it's an

continuity more than is not important

plus or minus one second let me grab the

other picture you are on the side with

the connector yeah we need a charging

connector

the thing is this that the picture is

not complete what do we have on the end

of the board yes there understand

[Music]

okay what about I can't see nothing here

hmm

I think it's going on the other side you

can check you can keep the we can check

for beeping yeah the header let me check

one second switch okay but you have to

you have to keep one of the multimeter

probe yeah on the plus of the charge

report okay so he sold out there that's

great that's great okay so keep there

and search for the MOSFETs I can see on

the end of the board I can see our

MOSFET there

on which one just

by the charger

he's beeping there on how many pins is

beeping how many pins no no check on the

the the mosfet pins on all four yeah

okay go on the other side

yeah go on the other side and check no

no no on the other side of the MOSFET

and check with the ground please nothing

yeah he's no important so now now we

have to find the second MOSFET try to

check from the from the output of the

MOSFET from the output now you have to

keep one of the output output yeah and

try to find the next one try to see

where it's beeping how many pins are

beeping

three three that's good that's good and

check on the other side of that MOSFET

with the ground no no with the ground

from the output of the second MOSFET

it's like he gives a little like big and

disappears okay one second would say

okay you have a green thing there next

to the MOSFET you have a green thing you

can check from that MOSFET if the output

of that MOSFET go to that resistor it's

a green thing yeah okay now yeah now now

sorry

yeah those are the MOSFETs now keep keep

one on that resistor on the green one

and with the with the other probe of the

multimeter go under on those capacitors

from the beginning you know in the

beginning when I told you to check the

capacitors it doesn't matter that there

is history like 0.1 ohms so it's no

important not there down so it's going

there okay so does that adopt us our 19

volts power I'll check with the ground

now with the ground from the green

resistor to the ground nothing

so you seen in this case we don't have

short to the ground

okay okay what do we need now we need

the charge of word to see exactly where

the yeah yeah that's what we have to do

next to see which one is close and you

know which one really so you checked

already

reg you the email I checked everything

and I just wanted to double-check it am

I right on that that's great that that's

fantastic

that's normal you you think I never

messed up it does not model these things

happen don't worry about that okay you

know what

you should put some something under the

motherboard because the the plastic is

to be metal over you see that the red

things yeah yeah okay that's good that's

good

so check straight on the other side you

don't have to keep the board in this

side not on on volts

yeah volts okay that's good

19 okay and after that one yes that's

not good and when you put the power

supply on the other side what happened

is short with the power supply okay

take out the charger take out the charge

unless do something together here now

set up the power supply oh 19 volts

around 2 amps no but I know you know I

know based on the way the arrow is on

the off the button but does the matter

is no important to films is no important

just and I want to come with you with

the - to ground and with the Plus on the

green resistor

Jeanne and I think the problem was an

other side know on the green resistor

yeah and check on the power supply what

happened 3.3 volts and how many amps but

you can set up more amps I can yeah go

up two amps

tell me the voltages see what is getting

hot something must get get hot check on

really you see you don't even need me

okay which place is getting hot okay

okay so I check the both yes it's almost

in the middle between these two no r22

MOSFETs one big one small

if I'm right one second is the car

either are two MOSFETs a big one and a

small one

[Music]

liquid which liquid from where yeah okay

yeah and the big one and the big one it

is doing no no I believe you one second

one second that's a power supply yeah

not the boat dot dot the big one and the

small one

two MOSFETs and they okay that will not

help me no no so that most what is

getting hot so if you check with the

multimeter actually son short okay let's

check with the multimeter on on the

coils you have two coils there yes on

the coils on the coils

it's like little done like what about

other quail sale okay okay let's check

that the two MOSFETs you have their two

most vicek for short

the both MOSFETs yeah but I want to

check for short with the probes on one

side on the other side of the MOSFETs

yeah but check on the other side with

you understand both probes want one of

the problem those side of the MOSFET and

the other probe on the other side of the

MOSFET you understand what I mean no no

where is the blocked probe because I

can't see the black one the multimeter

probe the multimeter wire the black wire

okay now check with the one side via

from the one side to the other side not

to the ground

no to the ground okay you know what I

mean yeah it's no sure okay check the

small one please okay check us yes

nice no short okay okay and that MOSFET

you said yeah yeah but does the thing

maybe the MOSFET is good and actually

it's are short on the on the power

supply rail what what powers of what

power realities is getting out from that

MOSFET thus thus does the thing is the

next to the the graphic chip so is very

possible to be the the graphics power

supply no no no no no you have to cause

there on the left hand and on the right

of the the two MOSFETs yeah why you know

which on the other side of the board we

have two more MOSFETs you can check on

the other side of the board yes so

actually there you have two power

supplies that's why you have two coils

yeah

check those muscles for short

so check each thing it's okay because

our three pins with four pins so it's

okay check the other one the other a

MOSFET is beeping there yes yes one

second does the one yeah so does beeping

yes that's bad

okay check with the ground please and on

the other side of the MOSFET with a with

the ground please yeah it's no beeping

with the ground true or not okay help me

with something you have two capacitor

two ceramic capacitors there next C if C

is beeping from the ceramic capacitor to

the MOSFET pin please yeah okay that's

our problem that Mossad

so that MOSFET is insured is no beeping

because it's a power supply you have two

MOSFETs on the power supply yeah and

like our own series serial mode and

because this isn't short will get hot

the second one you understand this is

like a wire obviously this will not get

art will get hot the second one which is

good yeah

good you have to check now because on

these MOSFETs you can't make sure this

is a power supply MOSFET check where is

the you have a dot on the chip see what

is the dot which yes which corner should

be on a corner okay you have our own the

board yes yeah okay let's take down that

MOSFET

[Music]

oh I know that HP model that's a nice HP

you have a graphic chip you have a good

processor yeah it's i seven no it's not

okay okay just just move the board a

little bit to see it to having a picture

the board okay that's great so now you

can come with the hotel just go for how

much you have there 450 450 and you know

just grab that chip with a with a

tweezer and you you don't have liquid

flux here one second one second okay no

that's a capacitor that big black one I

was thinking it's a connector it's a

connector or a capacitor that one yeah

is no plastic here it's a cop it's a

connector now it's a capacitor no it's

okay don't worry don't worry you should

you should just get concentrated you

know to take that chip without moving

nothing else you can try eventually

eventually to push the chip up you know

you know what I mean okay

okay you can do it I'm sure so 450 yeah

yeah butwe 450 you can play too much you

know when it's the solder is melting you

have to take out the chip yeah yeah

now I just you know that's it has to

move freely when it's moving freely you

can pull it out yeah okay now you have

to check that MOSFET with a multimeter

to be sure it's insured so it is assured

here okay okay let's double check yeah

let's double check go back to it to the

green resistor and come with a power

supply we 19 volts to see if we have

short anymore no no no on the other side

on the other side on the green resistor

no junior black to the ground yeah okay

and on the power supply if it's still

short I'll check on the power supply is

19 and arms that's great that's

fantastic that's all that's all yeah

that's all just take all the wires no no

no he's not taking arms you have to

press the power button to take arms but

we have to fix that power supply that's

not like a passing MOSFET actually that

most of it it is apart from a power

supply if we check my video you know the

path is two MOSFETs one coil and you

know so we have to replace that MOSFET

you still have the other board for

spares that's fantastic you see we can

take now the hopefully you have this

small mosque as there

so you see your first your first your

first feeling was that MOSFET is faulty

because it's getting hot yes you see you

see and actually if you'll start placing

you'll see you replace that with a

different one and it's still getting hot

and then you'll ask you why you know you

will you ask yourself why

but because the the the 19 was power L

is not coming to that MOSFET actually is

coming to this MOSFET which you took it

out and from the output of that MOSFET

is going on that one

okay okay let leave on this side one

second I can see you have some small

most as they're good now you have to

understand how you how you can identify

the MOSFET it's okay we can use this

MOSFET even if are not the same and we

don't even care what most bizarre but

[Music]

exactly why the MOSFET who goes to the

plus to the correct the capacitor that's

our MOSFET not the one which is going

with the pins on to the ground you

understand so you have to check with a

multimeter and find which one is going

to the capacitor exactly

so that's what uh with the paper mold as

well yes okay

[Music]

so the the top one here the one

okay the lower one that one is going to

the capacitor okay okay now check with

the ground let's double check with the

ground and see which one is weaving with

the ground the same one yeah but that's

not good let's let's have a look for a

different power supply because this is

confusing on that one yeah but we we

need a small MOSFETs now now we need to

find the path to MOSFETs a coil go on

the other side okay and MOSFET oh those

MOSFETs are from the coil yeah okay one

second how can we check how can I church

yeah that's what I am thinking you know

actually we need to you have to checked

with the beeping with the 19 volts power

L by DOE remember this board you have

any idea what is the 19 volts what is

the one second one second okay I

remember this board yeah from the ship

from the output from the area so you

have to check from there check from

there to the ground please see for so if

we have short or not because if we have

short it is

it's hard to be checked what about

another pin there is no short here okay

from the other pin from the other pin

yet the first one no no the first pin

there on the on the back of the

motherboard where are the MOSFETs I know

it's it's it's it's it's hard but try to

do it see you the SU on which MOSFET is

going

because we need one channel Channel and

I think I think the Buddha Channel in

any way or not I can't see but just keep

in mind on which one you can show me on

the board now that one yeah yeah okay

that's great now take it out now because

that's I was thinking it does the one

should be a dot should be a dot check

check carefully okay you know what you

know what don't don't worry about the

dot you know one side you have four pins

together on the other side you have

frame pins together yeah

so that dot pad with four pins and three

pins should match with your motherboard

that's very important the pins okay very

short are all all four together true or

not and where is longer are 3 and plus

one true okay you can take it out yeah

so actually our four is like a plate are

not pins so where are the short ones

have note pins there is a plate so you

can grab that most without

okay same 450 use of flux

no rush no rush

you need a another a little bit bigger

because the idea is to hit the board

because the board will suck your heat

you know what I mean in the future I

mean use up just a little bit nozzle you

know a bigger nozzle

yeah so everything is fine yeah okay

that's good that's good you can show me

that MOSFET from the back yeah on the

other side you see it's a play there are

no pins it's a plate okay okay let's

solder another worth so now it's very

important to see the board where are all

four pins together that place will be

there they see the plate yeah should be

where are all four pins together okay

you can use flux the flux it's always

good to be used so you can put now some

flux and after that you can put the

mosfet over you know

just a little bit yeah that's all yeah

you just put it now yeah you check the

position yeah okay and you have to keep

it down with with the tweezer because

the hot air will blow blow the most

without fifty yeah that's why it's okay

for short time you know but if you like

play there minutes the will be bad for

the board but just for replacing a

MOSFET quickly that that's okay

yeah leave it there and try and want to

move it on the position with the tweezer

if it's not on the position and all the

pins are sore Lord

that ship you know she'll move like

freely when the solder is melt you don't

have to push just try to move it around

like just a little bit just a little

touch

see it's okay if I think it's okay it's

okay so just cool down the area and

let's check to see if it's working on

[Music]

which side the important is the gate pin

to be soldered and to be like not

shorted with other ones yeah don't worry

about the play side don't worry there

about that side okay

okay well let's check plug the charger

and see what's happened the thermal pads

yeah you need one you need one

you should get a light isn't it yes well

we don't know okay let's check the 19

volts on the green resistor

nothing okay take all the charger and

let's come with the power supply in this

case we have it's on the green register

is 19 volt yes okay that's good that's

good

you have the power button there okay

check with the multimeter see if we have

3.3 volts

goodsoon 16 what's there no idea you can

take down the power button and put the

power button there I don't know if if if

we sure that pins it will come on

yeah there's not 3.3 okay let's try to

see you have the power button there

no nothing nothing yeah okay do you see

like bioship there because I'm looking

for a biochip I can't see a boy's ship

which one is does the - your startup

ship here but what about the bioship the

the black one from the other side is the

buyer ship on the opposite side of that

ship on this here here here here here on

this side of the board yeah on the back

of that ship you see that ship this ship

which you know what is the charging

connector up up up up up it's a black

ship there yeah okay what is writing on

that ship what is saying or not you you

sure

[Music]

but you can see exactly what numbers and

what is writing there because we have to

find a 3.3 volts power supply mxc I see

25 25 well I think that about ship yeah

okay you can see the pin number 8 from

that chip pin number 8 yes okay so with

the multimeter yeah I have to keep one

probe on on the pin number 8 and with

other probe to go on all over the Colo

all the coils and check for beeping

first check from the pin number a to

ground

it's not short here okay now go to all

on the coils yeah coils coils no no no

capacitor Queens no no on the coils yeah

yeah yeah and see which one is beeping

no it's one pin it's okay you don't have

to check on the on the both sides of the

coil what about under the the the RAM

memory slot there you have some quads

nothing

okay what about on the on the top of the

board top top top you have a coil there

nothing okay one second let me check go

down where I was that MOSFET getting hot

yeah and check on the board coils so

it's beeping he's beeping which one I

can't see just tell me which one is the

next two days decorator order one second

so that's the 3.3 volts power supply

yeah okay okay now from that coil go to

the those MOSFET and see which is

beeping from the quail what about on a

big one

nothing no okay now I have to I want to

keep that thing on the coil and go on

the other side of the board and check

yeah keep on the coil yeah

so what is beeping under under our

MOSFET is no beeping on our MOSFET here

on which one

no no beeping at all don't see any

others

okay the turn around the board because

there shall be a MOSFET a second MOSFET

except beeping on that it's just there

and on another yeah on the big one is

not going so it should be a check on the

other side again please Rico should be a

second MOSFET you know it does how these

things work

I found it

okay which one is so this one I can't

see so the one which you you replace it

we're next

does the one yeah we replaced okay turn

around the board okay set up the power

supply on 3.3 volt

three point three okay and comma ground

to the ground and plus to the coil to

that quail

so what do we have on the power supply

in Viet Nam's

[Music]

0.20 200 millions 0.02 or 0.2 zero okay

that's not good you have to keep there

and check what is getting hot go to the

the startup ship see if the startup ship

is getting hot the big ship you know you

know which one

No

something else should get warm warm no

heart no heart worm

what about the big chip now that one

that one that one yeah

No

you have to check even on the other side

of the board yeah well they're all I

don't know how you you can do it

you know what plug the charger connector

and see if you have light when you put

voltage there but without a charger you

just take out the charger unplug the

charger here okay that's good and plug

the connector and see if you have light

when you when you use three-point Frieda

Yahweh is not connected the connector is

not connect is not connected

you have light no you should be on the

charger isn't it yeah no no okay okay

plug the charger now take out take out

the or keep it and plug the charger how

do you wish and put now free point free

and see if you get the light on the

charger

no no like okay okay check with a

multimeter with our own volts yeah now

when the charger is plugged what voltage

do you have there on that coil

yeah well pretty much nothing 0.70 what

about on the MOSFET on the small line on

the other side okay turn around the Borg

let's check on the other side okay just

move the board a little bit to see you

having a picture yeah there yeah

and check now with a multimeter for

voltage yeah yeah

how many how much how many balls we have

there okay nineteen okay on the other

side okay what about on the most part

what do you replace it on the plate side

but III want to know on the play side

and on the other side on the gate check

on the gate okay okay now the things get

most more complicated you have to you

must have a chip there check if you see

you have achieved down down next to the

hole yeah there one second that chip is

getting hot

okay you have to check that shape here

okay okay take out the voltage take out

the the yeah and now check yeah check on

the MOSFET what we replace it yeah with

the beeping thing yeah all those pins

from the other side

check with the gate I just want to know

if the gate is short with the shorted

with other pins there yeah you see

that's the problem

okay let's you don't have a bigger

nozzle so you understand how these

things were that chip is driving the all

four MOSFETs just you show me I think

it's perfect use that one

so a little bit and try to get basically

yeah yeah

hopefully the hopefully that the cheaper

but no no it's impossible I don't think

that she died okay okay

nephew some flocks

you took out the the the charger yeah

yeah yeah okay

that's good that's good

just move the board a little bit left

the right sorry yeah thank you yeah

if you keep the tweezer on the chip

you'll suck the heat from the ship just

try to tease it and see when it's moving

and when it's moving actually you can

pull it out okay oh you see you see we

are getting the check for short yeah

no it's ok if it's ok solder back the

chip

so you understand just keep keep that

cheap yeah and use the hot air when you

see the soul that is melting just

release the the tweezer and leave the

cheap to like the get just sit by itself

you know without pushing because when

you push the cheap down the solder from

behind will pop out and I'll make sure

to everywhere you know what I mean you

sure the position is okay yeah okay yeah

I believe you believe you

oh just use the hotel more and you know

just just touch touch the chip with the

tweezer and see if it's moving freely

it is yeah okay so if you solve that

here it's okay if you think it's older

it's all that okay that's great that's

good just I want to check for short you

know we draw without pain with a gate

pin it is still short yeah

boy you sure does the gate because that

pin should be like separate from the

others yeah I don't know if there is the

gate I don't know if it's where is the

dot but check all four pins compare with

the next one yeah so check it for sure

and see if you should have free together

like short and one without

so it's not the one I was with with the

arrow shows not necessary okay I thought

is that too much rocks in it so you

shall not have all four pins together

you should have only three together

yeah well it still is beeping all four

together that's what I asked you just

keep the probe on one pin and check with

the beeping with the other one for each

pin and see if it's beeping

you can clean it with a toothbrush in

alcohol or petrol

[Music]

looks completely fine

yeah it's all for the the first and the

last one is beeping you can check the

first and the last one from the gate to

the other if one dough on the head on

the sides on the sides of the chip sides

the first pin and the last pin see if is

beeping together yeah that's bad let's

take those the chip

same way just you tease the the cheap

with the with the tweezer and when it's

moving freely you can pull it out here

yeah

okay okay now clean the board with the

petrol and I want to see the board you

know if you can bring the board closer

okay okay say you see oh there you have

four pins yeah three are together one is

not and one is not is the gate so if you

check now the pin number where is the

arrow yep that pin the pin number one

and with the last pin

yeah with P number four which that shall

not be pin should not be beeping yeah so

check now with the multimeter is beeping

how many homes do you have check again

or switch switch on ohms and tell me how

many ones do you have

I can't see just tell me how many how

many rooms do you have how much is

saying there twenty-eight okay switch

the multimeter on two hundred ohms scale

yeah

how many ohms 1.5 yeah that's bad that's

bad because because that pin is coming

from that ship that ship is the five

volts a 3.3 volts power supply and

actually your 5 volts power supply died

but they kill the chip so actually you

don't have 3.3 they're also that chip

yes tell me the name of that chip yeah

that's the one from the bottom

yeah yeah she'll be like I CL is oh you

don't have a magnifying glass or

something

[Music]

okay maybe now see try to change the

board angle maybe you can see from

different angle that's very important to

know what chip is there okay

so it's e w e eg 50 you're sure

well if it's this one yeah that's the

one yeah yeah so one more time

so E one second one second

II II from from elephant yeah let's try

W then we ask one second one second

Efram elephant here yeah okay

and so w e8 w fe yeah okay and then is e

50 I don't think we can find something

like that

so ii w as e f e from india here no

Efram elephant yeah yeah 15 yeah

no it's nothing like that online you

sure does the name well that's what can

i see that there's nothing else there

okay let's go again back to the

multimeter and switch on the dad mode on

the beeping mode here and tell me again

how much how many rooms do you have

there from the first point the P number

one and the pin number for a short is

completely shorter so it's nothing what

you can do you need that chip let me

check on ebay anything we can't find

anyway

no nothing on anyway so yeah you know

when you do just get that kind of bored

yeah I don't have that cheap if I will

have that cheap I'll send you that cheap

but I don't have that board

yes no I have boards there but not like

this one

probably this ship you can find it only

on this board

maybe you can find a faulty board well

you know what I will check tomorrow I'll

check on different boards we're sure

does the name try more you know try to

you I don't know without you know that

ear but and clean that cheap and and

then try to try to be sure about it what

what is writing on that ship I'll send

you yeah so ii w d s e15 sure does the

name it might be the second one because

that one because that one is like a

little bit scratched or something it

looks like that one it might be m oh

it's a but everything else is the same

so ii fy15

nothing

[Music]

yeah well that's it there's nothing else

and maybe it's not that chair he's not

worth the chip maybe it's not no it

should be together yeah yeah it's one

chief for the board power supply so the

nearest chip is that one well let me

have a look on the board's the other

side of the board you have nothing now

and there you have only one chip

you can check something more yeah to be

sure that's our chip here

go back you can switch the camera on the

on the board yeah okay you have the

other MOSFET the 3.31 yeah check on the

P number one and number four C check for

short

all right yeah

okay but you can see which is the pin

number one with the gate or the gate is

the pin or just try to find the gate pin

the gaping shall not be beeping we know

what we need we know one yeah that's

separate here keep the probe there and

with the other probe check on that chip

and see if is beeping so you see that

chip the gate go on that chip does mean

even the other gates will go on same

chip the other ship should go there you

don't know maybe it's ground you don't

know you have to take down the chip to

see if exactly the way is going there

don't worry about that your problem is

the chip does the chip does that that

chip handle to power supply three point

three and five volts I think five volts

but also can be a different voltage well

anyway your that shorted MOSFET here

bring probably 19 volts to the gate and

kill that ship because the chip was

shorted you know the MOSFET which we

took it down doesn't mean that MOSFET

pass 19 volts and probably that the the

the 19 volts come on the gate and kill

the chip

try to don't don't just keep the board

safe and try to find another board for

space or just give me some time to know

more and I'll check tomorrow yeah

because I'm sure you need only that ship

and that board will work okay yeah so

that's our problem because he's short on

the gate obviously is no signal they're

good okay it's okay but you learn now

you know how almost starting the

diagnosing and things yeah okay what

about on the other board another board

you don't have this ship really I think

so but you worth to check because

usually are more cheese like that

probably two free chips on each board so

you can have the same chip on different

power supplies

what's the check

now these are even different sizes yeah

what about it that cheap you know from

near from what he took out the MOSFET

you know where to cut the MOSFET yeah

yeah next it's a it's a chip there yeah

what about that one

it's not the same is different I'll have

a look tomorrow yeah eventually can send

me a no Facebook as the Skype is not

working on the on the iPhone same email

yeah and imagine yeah okay yes but

tomorrow yeah okay so have a nice

evening okay see you see you next time

yeah yeah
