I tried running my nice new P637 MME (Money Magazine Edition), and it chimes and boots, but without any video.

I wasn't aware that the Q/P63x needed a good PRAM battery to boot properly, but maybe it does?

When I first got it, it worked fine, so I don't know.

Caps? Aside from some slight leakage, the board looked very clean, and I don't recall seeing any corrosion.
