I bought this card on ebay from apress24 ( it's a pro shop ), but even if it "works" some colors are missing. Everything has a kind of grey/blue tint... and I found some physical damages on the back 🙁
Contacted the vendor by email, he first agreed to replace the card, then stopped to respond just trying to waste my time maybe trying to discourage me 😀 I had to open a case to ebay then a paypal dispute and I got refund and kept the card.

Here are some pics, do you guys think this can be fixed ? I've no idea how to change this capacitors as there's no value on them and 1 is missing..

I recently fixed a GeForce 256 DDR which was in a similar state (11 missing or damaged components), and that I also got for free after a refund from an ebay seller.

What I did was grab a similar aged (in this case I grabbed a dead Apple GeForce 2 MX) card and harvested similar physically sized capacitors from similar areas of the board (so if the missing component was a bypass cap on the rear of the GPU, I’d take one from the MX in that area as the voltages involved were likely to be similar), and an inductor for mine from the dead board and put them on the board I was fixing. For missing or damaged resistors I used high-resolution images from VGAMuseum to harvest the correct resistance values from the MX.

Sure there is the possibility that they are the wrong capacitance, but so far so good, and a working card with the wrong components is better than a dead card with missing ones!

Result is a fully working and stable card, and my GeForce 256 DDR was completely dead to begin with, no sign of life! Starting with a semi working card is a much better proposition!

If you aren’t personally capable of working with SMD components (easier with a hot air station, even a cheap one), then perhaps find someone locally who can help!

Those physical damages are probably irrelevant. I suggest using a contact cleaner spray in D-Sub connector, usually there is some mess inside those tiny holes.

Sorry but I disagree. It's likely that at least the missing cap is supplying that buck converter either with power or feedback. Without it the card won't ever function correctly.

100% try replacing the damaged and missing components with your best educated guess from similar cards (possibly even look up the datasheet for the buck converter, it might give a clue as to the value of the missing cap). It can't get any worse and is likely to get better.
