Hi everybody I need help with my GIGABYTE GeForce GTX 1060- GV-N1060IXOC-3GD

[gglcmw]

One mosfet blow up complete and now I can't see where the connection was in the PCB , I don't know if I can replace the mosfet
the thermal pad got some oil on mosfet and that is the reason that ending burning
Thanks from now on

 

[Blaeza]

To me, that looks ruined. If you can fix it I'll be very surprised.

What the f... did you run that card in a farm house with ten smokers or something? Its caked in moist and crap, metal is rusting at the I/O... No wonder something blew up. Be happy your house ain't on fire.

Don't even try to repair this card. Dust bin / recycle it.

 

[gglcmw]

thanks for your time, I only ask because I need to know where is connected the gate input of mosfet then may be I try to fix, The problem is very simple I have no money to another card so , there's no other way for me

 

[Blaeza]

Where are you from GGLCMW?

 

[gglcmw]

I am from Cuba

What exactly do you need to know , cant you just look at the others ?

 

[gglcmw]

the problem for me is that in the PCB I don't se where the gate pin goes, the other two pin , S and D I can see it

may be with a photo of another good card , same model of course

 

[Toothless]

Your best bet at any revival is EXTRA CAREFULLY scraping to the pad to see if there is any connection at all left.

I'm not a professional but yeah, that card is very dead.

Maybe this can help?

go at min 25.

 

[gglcmw]

yeah I know it's dead, but the only thing I think that may be I replace the mosfet and try it, even when I decided to take a look at PCB its was working but suddenly lost video time to time, so may be the rest are good and it can work again, only a possibility I know

yes I saw that video but I don't see clear where the pin its connect, The is at left and for me it is not clear in the video that part

 

[qubit]

If money is tight and it still partially works, perhaps you could take it to a repair shop?

Sorry, I can't help you with the board connections. Surface mount components are notoriously difficult to fix by hand too, requiring an expensive soldering station and skill. Good luck.

 

[gglcmw]

Yes, I appreciate your answer anyway, thanks a lot

It's Q40 NTMFS4C10N N-channel MOSFET 30V/46A/7mOhm (or the same as Q36 and so on, AON6414A)

But if this transistor has blown up, there is most likely a short on the board.

 

[gglcmw]

Thanks a lot for your answer, the problem with transistor was that Thermal pad over transistor cover it with and oil and that cause the blown up, even so it was working but time to time the card turning off till I take apart and see the transistor it was totally burning and I clean the surface in order to take a better look and well you saw the result in photo
One more time thanks for your time

 

[miant]

If your video card still works, you can just try to restore the third phase of the GPU power.
Q40 pin 1..3 must be connected to Q41 & Q42 pin 5 (NVVDD).
Q40 pin 4 should be connected to the common point of R770/R771 near U8 (see picture)
Q40 pin 5 should be connected to Q38 & Q140 pin 5 (12V)

*pins 1-3 and 5 are high current connections
*The thermal pad MUST have a good thermal conductivity.

 

[gglcmw]

Great !!! that's what exactly I need, now is very late at night but tomorrow I will try to fix.
I have no words to be gratefully with with your information,
I will tell you any result !!

 

[miant]

Okay, but first check the R770, its resistance should be 1 Ohm. If it is broken, it is highly likely that the U8 driver is also faulty.

this explains why your card is all rusty. I don't envy gamers living in tropical climate. All the humidity and salts in the air are a true nightmare. I hope you can fix your card buddy, good luck!

 

[gglcmw]

ok , I'll testing all around , one more time I really appreciate your help, today was a busy day I didn't have time to work in the card

 

[terroralpha]

i've repaired a few GPUs over the years (and failed to repair about 20), i just use the little arrows/triangles to figure out which way to orient replacement drmos components. i believe that is the "gate"? i'm not exactly educated in this. i learned by trial and error on dead components. this is the quickest way to figure out which way components should be oriented because technical documents/schematics are not available 99.99999% of the time

i believe the opposite side of where that arrow sites are all drain pins, and are bridged. so you realistically need to only find 5 traces.

if you do manage to fix it, i would probably clean the card first if i were you. maybe try to wipe down the card with isopropyl alcohol as much as possible to clean off the built up layer of salty humidity? again, i'm not an engineer or electrician so maybe this part is not necessary.

good luck

1. English only pls. Forum rules.

2. That looks destroyed.

 

[boarder]

Toothless: Yes, it is destroyed but I think it has repairs. there is nothing impossible

my friend gglcmw has a similar case
