Gigabyte GTX770 repair attempt

[jaroslav.psenicka]

Hi folks, a GPU repair newbie here, kindly asking for a help with my GTX770,

- the PCI 12 and 3V (kOhms to GND) as well as VCORE (~ 25 Ohms to GND, maybe too low?) seems OK
- there is a short (<1 Ohm to GND) in bottom-right section of the card (see image), both the inductor and capacitors around.

What is this powerline? 5V, PEX?
Can I just inject voltage, say 1V?
Or is it one of the mosfets? Can I test them in circuit?

Thanks for your tips, JP

Test mosfets in circuit: red probe on ground and black probe on pins !
