Toshiba PB6643 issue

A couple of months back the monitor in my Windy suddenly developed what I'd describe as a shimmer to the screen. It looked like interference or bad grounding but the cab hadn't been moved. We removed the flo tube and starter to rule that out. The shimmer would reduce after it warmed up but wouldn't completely go away, then today, this. Any idea?

Sorry to see that. My tube/chassis tech knowledge is limited (nil) so I can't be of much help, but if it turns out to be chassis related, hopefully Yosai or myself can be of assistance as we have a few non working spares between us that could be useful as part donors. Fingers crossed.

Thanks. I have a spare chassis. Hopefully that works. Do you fix these Grant?

Only other thing I could think of is something loose at the JAMMA harness as the Windy ones are a bit **** like that. Everything seems sound though.

give it bang on the side of the cab-does it affect it?

Nope.

Today it started off with the shimmer but after 5 minutes was all over the shop as per the pic.
