Hello! This is my first thread here. This is the first time I try to repair a shorted GPU, but I'm afraid that I'm short of knowledge to be able to isolate the problem. I would like to check if it can be saved, or it's too difficult/expensive and it's not worth to it (but I would love it!) I tell you...
I've got this shorted graphic card:
I see no evidence of damaged components, so let's see what happens with tests.
I detected a short in the 8-pin plug: without it plugged and the rest on, the motherboard run; with it plugged, usual short behaviour in the power supply.
So, I looked for the 8-pin scheme and found two:
One says that pins 4 and 6 are "sense" (I understand that they are connected to sensors or something for detecting or determine the current input), so I'm not sure about what their behavior should be; buuut found with the classic "beep" function with my multimeter that there is a short between pins 8 and 3, and 8 and 2. So I guess that some component is damaged, "bridging" or something. Of course, I haven't found any scheme of this GPU in the net (would be too easy, I guess!)
So, I've several doubts by the moment:
Cheers!

So, I've several doubts by the moment:
- For those who had already experience with shorted GPUs, which component (or components) do you think is more probable that is faulty?
- What are the "sense" pins exactly?
- What do you suggest for my next step?
- By the way, I've read about some cap meters that works with them within the circuit. Do they worth it really? I was thinking about getting one, just to avoid unsolding all the caps each time.
Cheers!
