Re: Shaky Star Wars

If it is happening on BOTH channels it almost has to be a ground loop
problem. Monitor input ground needs to go to game board, no duplicate
grounds to other places. Nothing else connected to monitor power inputs
either, they have to be isolated. It's a long shot, but could be
leakage in the isolation transformer causing current to run through the
input ground.

Didn't you say something about adding a ground? Also, does it still do
it with any fluorescent lighting off. You're not running another game
close to it, are you? You didn't add a fan?
