It's possible that this laptop has a small Ni-Mh battery for clock backup, and if so, it may have leaked and destroyed some traces on the motherboard. Did you disassemble it and checked if everything looks fine?

Recently I fixed a Trident card, which had video chip in exactly same form factor as Voodoo. I was getting video glitches too. The main chip just desoldered itself off the board, pins were floating above the PCB. You can see how it looks here in close-up (40 sec. in the video): https://youtu.be/ …

I had something like this in an LCD that got moisture in it, it also might been due to mechanical damage (pressing on these spots too hard, so the diffusion layers got mangled). It's an issue with the internal diffusion layers of the LCD screen and unfortunately I don't think there is an easy fix …

Thanks everyone! Also, where did the sound come from? Most early laptops didn't have onboard sound cards. This "laptop" has two ISA slots.

Also I'm not sure if these (really expensive) polymer caps are really needed as these weren't on the marked back then when 3dfx was alive. Polymer caps did exist back then (Sanyo OS-CON), and Voodoo 5 seems to be using them for the two biggest capacitors: oscon.jpg I don't think there is a need to …

You can try VirtualDub or VirtualDubMod software. Or DScaler http://deinterlace.sourceforge.net/ (DScaler is meant specific for analog video capture, i think it also can interface directly with the hardware?) I think I used them for both PCI and USB video capture, but that was long time ago.

I would guess that the left one is TV antenna input, and the right one is video capture input. There should be some minijack adapters which can breakout these ports to antenna and RCA connectors.
