GPU FIX ??? PLEASE HELP ME!!

[Leachey]

Guys, I am in desperate need of help, i smacked what seems to be a transistor of some sort off the back of the pcb and now no longer outputs video, i have found the trasnistor with the number “21132” stamped on it, its super small, I just want to know what this piece is called and if i can easily find another, i have decent soldering skills so i think i could pull off the repair, that card is out of warranty.

 

thank you!!

Try solder this one back first

One leg of the transistor has completely been pulled out and still attached the the gpu

So long as the metal connects you can get away with it. Only suggesting this because you say you're out of warranty.

It's a PNP SOT-523 tranistor, (or it could be a power MOSFET, I'm not 100% sure, or it could be a Schottky diode pack)  A117, maybe MCC makes it. Are the pads for it damaged? I do soldering work all the time on graphic cards for extreme overclocking.

thank you for your comment, is there is data base i could use to find out exactly what it is and what its rated for etc ?? I have a dead r9 290 i could get a donor transistor off and do some readings make sure they are the same, also what to the references on the pcb mean ? the serial referencing the transistor is Q521 would that mean anything ??

Yes, Q521 would be the tag on the PCB files for what part it is, while you could ask the board maker about it, what transistor it is and all, they'll almost 100% tell you to fuck off politely and spew some "internal documents aren't given out". You're best bet is to go buy a new graphic card with a backplate and learn from your mistake. While learning to volt mod I killed a GT 610, R9 380X, GTX 560, HD 6870, GTX 295, GeForce 6600 GT and a couple of HD 5450's. If you make a guess and that guess is wrong, it will kill the card potentially. However it looks like it's a positive MOSFET, or a PNP transistor, not sure of the gate drive and the collector and emitter voltages, you'll need to probe around with a DMM to find those.
