I don't think ceramics have anything like the failure rate of electrolytics.

The optic boards work fine; I just have to swap the two wires in the trackball harness. Ten seconds with a Molex pin removal tool vs ten minutes of disassembly/reassembly.

It's not the values I'm concerned with; what kind of caps are they? I already have the schematics. They say they're a ceramic disc type (.1uf), but these don't look like other ceramic disc caps.

My bad Peale, sorry. I'd have to check my board but the machine is DEEP in the shed at this moment. Like Chad says, they don't fail very often. So you already replaced C83,84 and 85 ? (Sorry if I missed that). Those are the electrolytic one's.

I replaced every electrolytic on the main board.
I know ceramics don't go bad often. There is no sign of them being bad (burnt, etc). I'm at a loss as to why this is happening, but truth is I haven't been checking too thoroughly. Since the graphics are okay, the high score saving isn't that important to me. But since it's not working properly, I am curious as to why. I'll figure it out sooner or later.
RayB:
Peale, does your cabinet have a light fixture for the marquee?
SirPeale:
No. Minis didn't come with one, did they?
I'm seriously thinking about putting on in there. It would look cool, IMO.
