Hi to all, I have a 970 mini that has Q503 leg 2 (IFP_IOVDD (backdrive prevention)) shorted to ground, If I inject 2 volts, only GPU heats a little (2 Amp draw), can I assume its a dead GPU?? or should look somewhere else? It came with some capacitors and resistors burnt from the analog part of the DVI (VGA output) and they are open, not shorted.
If I connect it to the PC, it heats reaching 60 degrees with no heatsink in 30 seconds, It isnt recogniced by the PC, so doesnt have meassured another voltages. Mosfets looks good and visual inspection is OK.
Attached schematics, IFP_IOVDD doesnt go to any other place as I can see.
Thanks a lot.
Resistors R596 and R600 are OK.
