Anyone know how to get rid of these moving lines I have going through this monitor.

A did a cap kit on it already. Fixed a bleeding color issue, but now I have these waving lines.

Cabinet has a 60-1 card installed.
 
you have some sort of ground fault, is the frame grounded and try connecting field and logic ground
 
Have you tried other boards with the monitor? It looks like electrical "noise" or interference, to me, but with those 60-1s being kind of made on the cheap, I would check it with other boards before trying to look for anything else.

I am thinking the same thing, but I think there are some rules for this. I think it has to be a screw type power supply, not a PC-style one, and you have to have a monitor that runs on an isolated power supply (I assume he definitely has this).

Assuming both of those are true, I think that would be a good fix to try.
