Killed my R9 290 - broken part on pcb

I have 3 R9 290s and recently tried to install a waterblock on the last card that didn't have one. When I went to start everything up I was getting huge problems. Tried the software end, even reinstalling windows, but didn't help.
Looking the the PCB, I noticed that something looked damaged/shorted. It's labelled D4002.

Can anyone tell me the chances of repair here? I'm able to solder if that's what it comes down to.

I took pics of the part as it is on a working R9 290 and also the damaged one.

Thanks so much in advance.

You broke the Standby LED. Did you drop the card while you installed the waterblock?
 
It's an LED, probably isn't even a required component, if you're decent with a soldering iron I'd remove it and see if the card works.
 
If you can't find a replacement, I've got a couple dead pcbs here that ppl have sent me over the years.
 
LED, hence D for diode as others have said. I doubt the LED being broken would make the board unusable, but who knows. Easy enough to replace.
 
Thanks for the input guys.... Let me try and remove it and see what happens.
I didn't drop it for sure... just the occasional tap while coming in and out of the case.


Funny thing, a transistor fell off one of the other cards. I was so lucky to find it just sitting on the desk. I soldered that and it seems to be working fine. I've been playing with components all my life and this is the first time I had these issues... maybe i'm getting old and can't keep my hand steady. Or maybe the quality is going down? Maybe just bad luck.

Thanks!
 
Ok so I removed the led. However, looking at the board again I think I found the real culprit.

Looks bad. Ideas?

Thanks!

That looks pretty bad, it appears that a number of capacitors have been ripped off. If you can locate the caps you might be able to solder them back on. I doubt the card will function with that many missing.
 
That's gonna be hard hard to fix because the solder pads are missing, ripped off.
 
Any idea on how I can buy these components if even possible?
As was suggested, I can maybe buy a dead card and learn how to solder really small things. lol. I'm assuming I can buy small solder tips that will fit on the iron I have.

Would they have been ripped off?
Could it have resulted from shorting out from water?

Thanks again everyone. Wasn't expecting such quick replies.
 
I have extra pcbs, you pay shipping but let me repeat, it will be hard to attach with a good solder pad. Your pics make it look like your pat's got ripped off along with the caps.

I'd have to echo this sentiment, I'm seeing at least two pads in your images that have been completely ripped off, without a trace left behind. If there's a bit of copper left in that area you might be able to solder a tiny wire from the pad to the cap, but we're talking about components that are smaller than a cake crumb here so it's easier said than done.
 
Thanks guys.
Might be worth it as a side project. Still got the other two so not in a hurry.

Thanks again!

Good tidings . This is as easy as cake to fix . You don't need years of experience to solder , those tiny resistors . All you can do is grab the exact ones ,either online or from a spare card , afterwards use a Heat-gun and flux to solder them. I can guide you further . Don't hesitate to ask mate.
 
While there are pulled pads, the pads were connected to a via, which those appear to be intact.
You should be able to solder new parts onto those locations.
You will just need to figure out what values the parts are so you can buy new ones.
Also, you may need to remove some of the masking off the vias to expose some copper to help make a good connection. Don't scrape to hard as you could damage the via.
 
It got it working!! Thanks to everyone for their help. Special thanks to thesmokingman for sending me a board I could take parts off of. I really appreciate it.

I'm no soldering specialist so it took me a little while. It took more patience than skill really since the parts are so small. Ironically, I didn't end up using the thin tip with the new solder I bought since it didn't head up the last few millimeters. I ended up using the bigger rope cutting tip since it also had a sharp point, which heated nicely.

I only reattached two bigger resister/transistors, or whatever they're called, and one small one. The other smaller ones I left. IKV1476, I didn't see your post otherwise I would have tried scraping a bit and then soldering. But hey, it's working perfect right now.

Here are a couple pics.. feel free to laugh. lol. Sorry for the bad focus on the first one.

The broken led I removed and didn't replace.


On a side note. While I prematurely mourned the loss of my third card, I wondered if I should sell the two and get the new GTX 1070, which would almost come out about even cost wise. I did some benching and compared my results with the GTX 1070 results I got online. Settings were on max/ultra. In the end I'm happy with the threesome I got going, despite the occasional stuttering, and some games not supporting crossfire. The 3 stack up well against the 1080 too.
Here's some of the results I wanted to share:

Arkham Origins: BF4: BF Hardline: Bioshock: Dragon Age: Doom (no crossfire support): Metro 2033: Shadow of Mordor: Tomb Raider:
3x R9 290 83 77 70 84 47 XX 48 98 89
2x R9 290 73 52 50 68 24 31 42 71 63
GTX 1070 67 44 34 53 22 48 44 49 47

Oh, I ended up finding another broken part after I first the thread, which is the one in the second picture above.

I would go 1070 like you suggested.

Less stuttering so it will appear smoother then a 3 card setup. Also more support, less power used, less heat.

The power is a definite. Even just one R9 draws so much juice.

As for heat I have them all in a water cooled loop. Which solved the noise issue as well.

Unless you are exhausting out the window that heat in the water loop has to go some place.
 
Nice job on the repair!

I used to work as a bench tech repairing boards every day so I know what's involved.

Honestly, I would have only given you about a 10% chance of fixing it.
Several parts missing and the board damage.

Again, nice job..... I'm impressed.

Just handle those boards more gently! :)

Thanks!

I think I've been spoiled. Been playing around with computer parts for so long. This is the first time I've had a problem really. I wonder if they make the parts, or even the "glue" they use cheaper these days. Or maybe I'm getting older and rougher. lol.
I got a new appreciation for back plates for these things. This way the card is protected. But they are expensive for what they really do.
 
I can't even tell... looks good as new.

Nah, you can tell. But at least it works!!
