I am also very novice but from what I have learned form watching Alex is all those components being bad at once is very doubtful. I would be led to believe it is a fuse or filter that is giving you bad readings down the line. I would probably check continuity across them. But again I am a novice. Hope you get it sorted.

Thanks for your reply!
I was wondering that as well but I've got a hard time sorting out all of the components for what they are.

I figure it would be a lot easier with a microscope though... ?

Oh yea it would i been using one of those desktop magnifying glass with the light in it. I just watched this a couple days ago. Its a 3080 where Alex troubleshoots by checking the power rails it might help.

You seem to have a number of inductors and diodes marked here, but those are supposed to measure short, because they generally are. In the case of the diodes, if they measure short in reverse, that's something else, but it's far more likely a single cap or mosfet that's shorted. When looking for shorts, your best option is usually to find something thermally. A common cheap way is to pump some voltage into the board, try to find a spot that's getting warmer than the rest by touch (assuming you don't have a thermal cam). If you can find the general area, spread a bit of IPA around that area, and then pump voltage again. Since IPA has a pretty low boiling point, you'll see it evaporate faster around the shorted component than anywhere else. It doesn't always work, if the component isn't getting warm enough to really cause the IPA to evaporate faster. You can also try getting the flux atomizer pen and do it that way. In any case, heat is usually your best indicator of where a short is located, and then removing suspect components until the short disappears. Once that happens, try replacing the specific component and see if the short comes back. It's possible that it could be two components along the same path, but highly unlikely, given how shorts tend to bypass everything else in the circuit when they happen.

Hope that helps

Thanks for your reply!

Is there some easy way to apply voltage, like USB charger or something?

Don't have any fancy tools.

I remeasured everything to ground (measured each component before).

Don't know if this helps but attaching some photos, again short to ground marked with red.

Thanks again!

You need to go back to the basics and familiarize yourself with how the card works. Know your rails and how they should measure in voltage, diode and resistance modes. Figure out where 12v, 5v, 3.3v and 1.8v rails are and measure those for a short. If no short, plug the card in and measure those voltages. If any missing, start investigating. No easy wat to figure it out. Graphics cards are complex is design and not easy to repair. Without proper tools and knowledge, you won't get far.

Thanks for your reply and your input!

I'm trying to learn from you all. 🙂
It's just that some components are difficult to identify.
Guess I need to get myself some textbooks.
