XFX RX470 Not Working
Hello to everyone I have an XFX RX 470 4GB that when is connected to the PCI-Express slot don't give any video output; I've seen with a Thermo camera (see images) that all the ram don't get hotter and the MOSFETs driven by the controller APW8722 seems cooler like they are not driven (maybe APW8722 dies??), there are no shortcircuits on 12Vdc and 3Vdc....

Re: Rx 580 8gb powercolor red dragon not working
From the pictures on this website seems that it's ok that the component is not mounted, I'll continue my investigation.
PS: My card is the golden sample one

Rx 580 8gb powercolor red dragon not working
Hello to everyone, I've bought a not working Powercolor RX580 8GB to try to fix it; Immediately with a multimeter I've seen that on 12Vdc that we can found 8pin and 6pin connectors there is only 700Ohm between the 12Vdc power line and GND; also someone has tried to rework the board, I've seen both mosfet 4C05N are in short circuit between drain and source (bad soldering work I can say, see image).
I'll try remove the mosfets to see if the low isolation disappear, does anyone have this board? can you tell which mosfet do you have mounted? do you have some schematics? do you have a board...
