Monitor Advice - Vertical Collapse?

[sapporo46]

Got a suspect monitor chassis with a noisy flyback, now it's doing this.

Does this look like the beginning of vertical collapse? It needed looking at anyway, but this seals it.

The image only changes when I tap the side of the cabinet, as in the video.

Bad contacts on the remote board or bad H-amp potentiometer could cause this issue. Gently move cables and parts around and see which one is making trouble.

Thanks, will give that a go.

Necro bump for this thread helping me out tonight on my JAMMA cab. The remote board just needed reseating.

Everyone loves an easy fix.
