to send it to a qualified person out of my country will cost me much money
is there no local repairer on your area? where do you live? if you're in us or europe i don't think you have to send it overseas. maybe you just need to buy some parts from overseas, if there is no parts around you.
No there isn't, I'm from Africa and around me there is no expert at all, they mostly don't even know what GPU is and those who knew what GPU is are the sellers, imagine sending the GPU overseas to get repaired when waybill is insanely high
I think you have two options:
A) Risky: Go on youtube and absorb all the videos on graphics card repair. If you are lucky they may have your card. There is a set of tools that GPU repair dweebs use.
B) Conservative. Extract remaining value out of this card by selling it as a not working card on some sort of EBAY. US EBAY probably has about 10 guys who buy non working graphics cards. I suspect China and Russia have the same demand

For 2 pages of discussion, it is not clear which video cards are being repaired.
Initial diagnostics will require a soldering station for at least $ 50 if the user knows how to solder.
Because other elements cannot be checked until they are removed from the video card.
