Was helping a friend out who just bought his first game (Ms. Pac). There was no picture, but the game would play blind. I pulled the chassis and finally got around to putting in the cap kit.
Plugged it all back up tonight, and after tweaking some knobs we have a good looking picture! Unfortunately there's also a 1/2-inch dark vertical band that moves from right to left (up to down if it were horizontal mounted). There's also a buzz in the speaker. I'm guessing grounding issue, but I thought someone might have a suggestion where to start looking.
I'm also not ruling out an issue with my soldering job but I double-checked it and everything looked fine as far as I can tell.
He'd sent off the Ms Pac PCB to have it checked out/repaired and it came back with a clean bill of health as-is. I also don't remember the speaker buzz when I checked it out the first time. I tried to get a picture/video, but as luck would have it that's when my phone's battery died.
Luckily it's a surprisingly clean cab on the inside with nice, neat factory wiring.
