Help Repairing an R9 Fury!

Hey guys! I recently won an auction on ebay for a Sapphire R9 Fury Tri-X for $30 shipped, listed for parts or not working (However it was never stated what was wrong with it). Plugging it in my PC, and I was greeted with some artificating (Very thin red lines) and would black screen when installing drivers. So, I took it apart, and upon further inspection, I noticed there was a burnt surface-mount capacitor. I brought it to a local PCB Repair shop, and they replaced the capacitor, however, when he went to remove another capacitors near it, he stated it fell apart. So, he went ahead and replaced both capacitors. (You can tell in the photos, they're on the back of the card, near the VRM)
He didn't charge me because I would be doing the testing, so I brought it back, put it in my rig. Same problem thin, redline artifcating. . I monitored to see if there was any smoke coming from where the new capacitors were soldered on, but there was none, so I'm assuming there's damage somewhere else on the card. The day I brought it in, he pointed out that there looked like there was a surface-mount capacitor replaced behind the Core it self (Located on photos)
Anyways. What should I do? I'd like to get this card fixed.

Bumping, I just uploaded a video showing and explaining the situation in better detail on my YT Channel

IDK if Tantelum cap's usually fail open or short. But if it's the bigger tantalems ones on the board there in the center, they're more likely between a voltage rail like 5V or 3.3V , and ground. So if they fail short circuit, a ton of current could flow and even burn the copper traces inside the PCB.

These things really are black boxes, with no schematics available, practically no one working on them besides maybe re-balling chips. And getting the actual replacement chips usually means buying another card to salvage from.


I have a broken soundcard, mobo, and GPU. I'm fairly new at EE and have some nice equipment, but yeah it's a black box alright, even with broken fuses to start from like on the soundcard.

The guy from the repair shop said it failed open, not shorted. Which is good I suppose.
