CPS2 A-board powering on infrequently

Hey,

Just shooting this out there before I just order another A-board (need one any ways), but lately my ST cabinet hasn't been powering on when the arcade cab has. I can only figure it's one of two things:

The PSU
The A-board

All lights and monitor come on. No game sound is playing through the speakers. No game video is coming through the monitor. It will sometimes display video/sound but never one over the other.

I believe this would mean the A-board is probably dying or is just having bad connections.

Thoughts?

Thanks for any help/tips/info.

Clean the jamma edge of the A board. Almost always it's that. Use a pink eraser followed by some contact cleaner.
