Konami Windy's Monitor Flickers When Bumped

I just got a Konami Windy for my vertical shooters. The monitor plays a good picture but whenever I bump the cab slightly or even hit a button too hard(too hard really isn't hard at all) the monitor flickers. I'm sure this is an easy fix, like a ground wire or something but it's pissing me off and I'm not sure what to do about it. I can take pictures of the setup if that would help anyone in solving the problem. Any infos much appreciated.

I know someone here must know what causes this...

The only help I can give is..you have to look for a breaking/loose/cracked wire..

It could be on the power supply/Monitor or harness itself..
If the harness/pins is to loose on the edge connector it could cause this...

I think it's a loose wire somewhere...

perhaps a dry solder joint on the monitor pcb. try moving the harness with the cab running, you may be able to identify where the more sensitive areas to movement are.

Oh yea...
Since the monitor in my candy cab plugs in(AC Wire) within the Candy cab itself..Make sure that plug is in right/not loose or coming out.
