The video card contact is damaged, can it be repaired? If yes, how?

Question

Do it yourself

Hello! RX 470 video card , computer won't boot, fans are spinning, blue LED on video card is on. There is no image. Can contacts be restored?

Answer 1

The contacts burn out as a result of a short circuit on the video card board, so there is no point in restoring it until you fix the dead video card.

Answer 2

Check with a probe whether the burnt contact is connected to its "brother" on the other side: https://ru.wikipedia.org/wiki/PCI_Express#PCI_Expr...
If there is a connection (resistance below 0.5 Ohm), then you can try to clean the deposit (eraser) and test.

Answer 3

Yes, maybe not too difficult. Restored somehow completely broken off piece. You should buy a donor, the cheapest one. Boron cut off a piece of textolite with contacts with a machine and fit the same piece from the donor, glue it with resin. At the roots of the contacts, wipe off the coating and solder with a thin wire, I took the charger from the transformer. If you solder not at the root of the contact, then the wire will rest against the bus. Then be sure to varnish. It is useless to build up contact, it will constantly fall off.

Answer 4

Of course you can. Take a soldering iron (if you have no experience, practice somewhere) and restore. The work is interesting, but jewelry.
