Default Zotac 1660 ti Shorted

Hi all,

I just got that 1660 that someone shorted by touching a metal plate to the back of the card.

I found that U15 (ALNB 9614) has a hole in it. Any idea what that is so I can buy a replacement?

Also, all these caps in the photo measure 0.2ohm which I suppose is short, as this is what my multimeter measures ground to ground as well. Measurement taken after taking off the burned IC.

You can just about see the AO logo at the top left corner,its an Alpha Omega OZ2261NQI

0.2ohms is short,maybe a shorted cap somewhere

Thank you for that!

All 3 marked locations are shorted, should I assume that's short to the vcore?
Can I inject 1 volt in on any of the 3?

Update:
Injecting 1v gives 6a and warm GPU
