Not sure what's the correct term for this issue, but video will explain:

Put up a new video in the first post.

The issue is somewhere on the chassis. I've tried the monitor in a different cab, with a different game and with another remote board and remote board wiring, so I can rule out it being the fault of the game, cab wiring or remote.

The issue manifests sporadically. It's gotten progressively worse though. You can hear a faint chittering (I honestly don't know how better to describe it) on the chassis when it's doing it, but it's impossible to pinpoint by sound alone. I gave all the pots a good tweak and the caps have been recently changes, so it's not either of those.

Any ideas?

it is not related to b+ otherwise your picture would change size,i don't think it is related to deflection-it looks like solder connection issue
check the neck card crt socket
