I've grown impossibly frustrated with this issue.
Have an old Williams Multigame I'm trying to get working. Can't get the smeared text (pictured) to go away and get a clean picture. Board is tested in another rig. Tried 2 univeral chassis' I had laying around on 2 different tubes and the problem persists!
The setup - power goes into original Joust power brick, isolated voltage to the monitor,
128VAC at the wall, 136VAC at the switching power supply (coming off the Williams transformer), solid 5.02V out of the power supply. Everything is grounded properly. No other electrical devices near causing interference.
Despite them being universal chassis' they seem to work well. What am I missing here?
