Hi all
It's my first post here, been a long time lurker.
I'm looking to get some advice on repair of my Voodoo 5500 card please.
I put the card away years ago when it started artifacting. On post it would show the 3DFX bios text but it would have lines missing from it. After watching loads of repair videos I decided it was time to try and fix it. I read https://3dfx-alive.de/3dfx-troubleshooting-guide which pointed me towards the memory. So I removed one at a time the video memory on the primary processor. I didn't see a difference when I got down to the last chip. At that point I tried removing all memory from the secondary processor. Still no joy. I bought some replacement memory of identical kind (new old stock) and replaced all memory chips. (admittingly this did not go completely smoothly given my lack of experience soldering something so small, I removed a few pads, but they seemed to be non connected, so wasn't worried.) I've triple checked all solder joints on the memory, reflowed and cleaned. Replaced a resistor that was missing on the back memory (r527)
Unfortunately my problem persists. It's a strange one, I suspect my be due to problems with the primary processor, but I'm hoping that someone else will know otherwise.
