recently i bought a box full of old hardware (some good pieces, some regular) and found a voodoo 3 agp but upon some close up inspection i found that has 2 components burned, can be repaired?
that looks like a V3 3000 (judging by the heatsink). If the pads under the burned components are OK and there are no broken traces, it might be repairable.
sorry to post it on the wrong forum. this are the 2 best close up photos i could do:
Two 'Nichicon S1G' Capacitors SMD? of unknown capacitance..

Looks pretty bad in the affected area.

i think it says "LTu95 S1G" on top of the burned capacitors
Could you perhaps clean up the burn marks (just see how much you can remove, but try to not do any further damage and be gentle) and perhaps take a sharper picture? It really depends on the damage done to the PCB if it can be repaired or not.
From what I could tell it's not looking very good, so nothing's lost right?
That's going to be fun to fix.
Remember there's probably a reason the two caps blew. Maybe they were bad, maybe a bad psu? Or something else is bad on the card.
If this was not a 3dfx card I'd scrap it, but being a 3dfx card is at least try and fix it.
You're need to clean up the card before fixing it and may have to relocate the solder point for the caps. Nothing too hard, just mind numbing and time consuming.

^this.
Carefully UNSOLDER (don't pry them off! it will damage the PCB!) the burned components, then use a good cleaner (like WD40 SPECIALIST Contact cleaner) and a toothbrush to clean as much of the black stuff off, then do a close-up of the damaged area.
Hate to put a damper on Your hopes but I reckon You have diddly squat chances of fixing that.
Looks like the board has been burnt to the point of charcoal in that area. Charcoal is conductive so that whole
area is likely one big short circuit. To add to that who knows how many layers those boards have, certainly at least 5 I would think.
Then You have the chance that layers beneath the top are burnt and shorted as well.
Good Luck 😀

I checked my V3 AGP card:

S1G
Both are the same. I asked if these are capacitors, but I got an answer that they might be operational amplifiers too. 😕
Those are diodes and not capacitors, look at the PCB marking (CR), it's purpose there are to protect rest of the circuit from shorted voltage regulator, so that is the case of charred diodes.
Is it worth repairing now?
-if you don't have skills or right equipment and plan to bring it to repair shop, not really.
will it be worth repairing in the future?
-definitely yes.

That makes more sense, forget what I guessed.

ill send it to a specialized repair shop, follow up in a few days.
