So I decided to start restoring my New Astro City which hasn't been turned on for years. I noticed a little bit of a wiggle a years ago, but now it seems to be out of control:


Is this common? I assume it's probably a capacitor, but I figured I'd check here first.

I tried two different boards and two different power circuits in my house, so unless it's the JAMMA connector (I doubt it) then I guess it has to be the monitor or the PSU that's the problem.

My guess is power related. Try plugging into a different household circuit via extension cord. Else, recap your PSU.

Could be caps, or bad joints. If it’s still on the factory caps, start with a recap and also do the filters. I’ve had similar issues disappear when I reflowed all the points.
