Hi to all and thanks for your attention

I have this 580 (maybe i can have one working), with all the voltages and resistance in order, but im missing PX_EN and DRAM_RSTA, the gpu goes warm, but i cant reconignize it on windows or other OS.

The seller say goes black some days ago and nothing else, some months ago changed thermal compund (paste and pads).

If anyone can help me i appreciate

PS i dont know if its permitted by rules but i can pay if we can fix it.

many thanks

Look for white capacitors:

Thanks to your time!
What cap do you mean? Ive tested all the cap near the pcie connector and j read 0.230v for each one...

Ive tryed to test the 2 cap near the q1077, both had one side at ground the big one had other side connected to pin7 of u200 the other one i cant check with multimeter in diode mode and I cant follow where it goes...

Did you get any solution I have exactly that problem on two video cards.

PX_EN

It is very important signal. How close to the GPU did you search for it? It goes through a series of resistors and 0 ohm resistors. It is connected to many places. A shorted transistor somewhere can pull it down along with DRAM_RSTA.
For example this dual NPN could pull these signals down or up permanently.

But you could support this forum with $99 :-) It is not a big deal for us westerners but definitely will help the forum to grow up.

Did you measure the whole net? What is a voltage drop and resistance of each signal in a different points? What is the exact model of this MSI card?

I have a 580 nitro rx here with the same problem.

на Сапфирах PX_EN появится когда карта будет стоять в материнке.
