I have an R9. the problem is not unknown. I know clearly what happened. I was working on a home made fan I took from a server and one the PSU molex wires were exposed and grounded to the case or the 5v+12v touched and grounded. There was small spark and poof and the system shut down.
The card never turned on after that. No burns its like new.
Interestingly the power led's work, green when PCI is on and red when is off so its getting some power. However the card doesn't display anything and takes about 3 tries to power on to get the fans on, but never turns on display or detects as a slave when using multiple cards.
So no burn but no display / detect either.
My first guess was that the card is ok only the ROM got corrupt. But i'm not sure if this is even possible since I don't know video card architecture much.
I'm familiar with board level repair, did many power supplies since they're easy but not much experience with video cards and looking for a starting point.
