Anybody got a gtx 1070 fe that can do me a favour?

There is a PCB pic here, there should be something there by the looks of it.
NVIDIA GeForce GTX 1070 Specs
NVIDIA GP104, 1683 MHz, 1920 Cores, 120 TMUs, 64 ROPs, 8192 MB GDDR5, 2002 MHz, 256 bit
Do you do GPU repairs often? I have a dead 1070 also that's always bugged me why it died. I'd love to know and then use it in my nephew's PC.
Edit* ignore me I was looking at the coil...

Best photo I can find: https://images.anandtech.com/doci/10325/GeForce_GTX_1070_Front_PCB_1464309557.jpg (edit: just realised you can zoom in, but still can't read the markings on the component itself annoyingly)
From your photo, it looks like it says L31, would that not typically indicate an inductor? (edit 2: D'oh, had missed what you said about the missing coil so was looking at that....can't see a resistor on the pic I've posted above, see below)

Ignore the coil.. only after the resistor next to it... just about to test it... New mosfet new inductor, all shorts are now gone.

Well I don't normally do gpus but this one is fixed...
I also happen to have quite a few gtx parts in stock now so if its common vcore fet failure I can likely diagnose/fix it.

Well done the @Vince !
Is this from wear and tear or when people move the components about knocking it?

Mosfets blow, they get hot they stop operating effectively and they sometimes blow. If a fet blows you will normally get a short 12v to ground. This one I replaced the fet and the 1R0 coil which was missing. It will be on its way back to its owner tomorrow and hopefully give another few years of solid service.

Oley sheet it looks like nothing is in the case lol, so much space!
Blinking heck! Well done.
11 out of ten for your ability to find the dud component there.
111 out of ten for your ability to replace it.
I struggled back in the day to replace the odd miniature surface mount resistor when things started going stupid small from a repair perspective. Components are even smaller now. From the pics, I can hardly see that mosfet.
How did you do it? I'm guessing you didn't use a standard 25w iron....

I only used my iron to clean up after
... I repair all sorts, normally consoles, mostly game gears, switches, but really anything. I have a lot of tools including hot air rework station, t12 temp controlled iron, 1200x digital scope, oscilloscope etc. But to repair this was honestly pretty easy! Much easier than troubleshooting a switch.I have a repair thread hidden away on here: https://forums.overclockers.co.uk/threads/vinces-ebay-repair-thread-console-repairs-mods.18940033/ It sort of documents me starting to repair stuff more regularly (ive been repairing all kinds long before but not to this degree). It's also a long read!

I'll have a look in a bit at your other thread. Don't tell a soul but I was once proud to call myself an electronics engineer. I loved it and my years at college studying electronics. Eyesight not so good now and, well, to be candid, I haven't kept up with modern techniques and stuff. Still do it for a living but in practice it pays to swap entire boards and send the dud back to manufacturer for repair. I am in awe of you chaps who can do component level repair these days.
Thats exactly why I need a scope, coming up to 40 now and some of these components are tiny, without a scope it's game over. I only do it as a hobby but do enjoy prodding around with a multimeter

It's on its way back home - Special Delivery pre 1pm tomorrow. Please update us in my repair thread so I know all is well. I have sent you a PM with the details. Thanks everybody who chipped in with the images, much appreciated.
