Hi,
I am troubleshooting this graphic card I got second hand already faulty and not opened. The fans start but it is not detected. I found that the rail PEX_VDD has 0.4 Ohms, I think it is supposed to be around 30 or 100 Ohms?
I did remove the coil and the short is on the GPU side, not the mosfet side. Since I did not find the boardview for this card I did manage to locate a couple of caps connected to the rail and removed them, but no luck.
I did try injecting 0.75V and it was delivering 3A. With an IR camera I did not find anything getting hot. It could be that the GPU was getting slightly warm, but because of the reflective surface I am not 100% sure. By touching it looks like a bit warmer than ambient temperature, but little.
VCore, Vram, PEX not present. The rest of the voltages are.
Do you think there is any hope?
Thanks!!
