I had a similar effect happen with a mame pc in a blast. Grounding the PC properly eliminated the interference. So +1 check your video grounding.I have a MS8 in a Madonna and it had some diagonal line interference...turned out to be a ground wire(earth) that was connected to the replacement PSU. Dunno if it's gonna harm the CRT over time, but at least the pic was clear now that I unhooked it.
You could just recap the one that's in there with quality parts. Full on replacement is likely unnecessary.Any recommendations for a good PSU? This one’s build quality is sort of shit, I would be happy to swap it out anyway.
