RE: Star Wars/Wells Gardner 6100 Problem

Yeah, I think there's a good chance that the low voltage section just
failed on your monitor. (It *could* have taken out a deflection
transistor or two, but I've seen far more bad low voltage circuits than
dead deflection transistors...)

If you buy one pre-assembled installation shouldn't take very long at
all.
