EVGA GeForce GTX 1060 SC missing capacitors and grilled one

[pwrrang3r]

Hi,

I've got EVGA Geforce GTX 1060 SC with some damage.
Could someone help me to identyfy capacitors values please?
I'v been trying to find any reference pcb schematics/boardview but with no results.
Pls find attached photos of damaged caps.

Tks in advance and have a nice day.

I can't help much because the lack of markings, but you can look for the 1060 schematic here and trace the connection with multimeter, I found the C122, C121, Q33, and Q509 there.

Thank you for prompt response. I found these schems few days ago but unfortunately there is a file which I can't extract (maybe it's broken - MSI_IGE_CAD). There is 0bytes
I was trying to trace it basing on MSI schematic but (maybe I'm doing something wrong) for me values are different to this schem also markings are different - C122 does not exist on my pcb, q33 - can't find on pcb, Q509 is empty (but grilled capacitor is connected to Q509 2nd pad). This grilled one also is strange because one side is ground - that's ok, but second is 12V - I trace it as a Q11 and Q13 on my pcb (AOE6930 D1 drains). I don't really know is this good or not but card is giving picture - when I start GPU-Z to check card, there were only blind cells without any info
Could this be a short on pcb?

Maybe you could tell which components were defective and what values they have.

My bad, sorry. I was in a hurry today.
On back side there were two missing caps:
0402 - 1uF
0603 - 10uF
I desolder two from card - for me same layout and it's working - yellow circles on attached foto.
Grilled one on GPU side - I've just put 0402 - 1uF - I just guessed.
GeForce is working fine atm.

Hi,
if you still have the card at hand, can you tell me what's the resistance to ground from this inductor (marked in red, behind the 12V -> 1.8V buck converter)? Mine measures at about 55Ohm and I'm not sure if it's not too low.

Hi,
Sorry that takes so long but I have to find similar card. One I found has 4.9 kOhms but be informed that this one probably has damaged GPU.
rgsd,
