Hi! Is just got a Powercolor Hellhound RX 6600XT gpu, it was listed as a non working card, and now i am trying to figure out what is going on with this card. The symptoms are:

-12v is not shorted

-all VRM outputs are shorted to GND, measured at the points marked red on the picture

-did not find any obvious damage to the pcb, or any missing part...

-powering the card end up triggering the bench power supply current limit, and then shutting off the card (after current limit, the current drops back to zero, i guess maybe the current protection on the PCB itself)The power supply is capable of CC mode.

I am new in the GPU repair field, so please help me with some tips to repair this card. I also looking for the schematic of this card. Thansk for the help!
