I hope you are NOT using the original +5VDC power supply! Sounds like
ripple to me. Plus they have a bad tendency to burn the ground connectors
and this will cause a ground fault (ground voltage reference) that can fry
the monitor. I REALLY recommend that you wire in a computer switching power
supply to this game, plus hook up a 6VDC relay across the +5VDC supply and
wire it so if the +5VDC fails then power is cut off to the monitor. 4PDT
relay with ten amp contacts would work very well here.
