Very possible. If you've tried this deflection pcb on several different
games, and it exhibits the same "problem", then it's probably not a game
pcb problem. If you have access to a scope, measure the DC off the LV
supply and zoom in to see if there is excessive ripple. If so, replace
transistors/caps on LV supply or install an LV2000.
Only other thing I can think of off the top of my head, is that you are
getting some kind of 60Hz noise in the monitor. 60Hz noise would show up as
slow wavy stuff. This would be caused by a grounding problem. Does the main
power cord have a ground plug?
