I know, I was a little quick on the reply. I have seen a missing color problem cure
itself on a monitor or two with the flyback change. It depends on the flyback
construction too, how much is consolidated into the HV system. The flaky focus
sounds a little like heat affecting the diodes, like it's ready to pop a flyback as
well. Probably 6 of 10 monitors I work on are flyback related, 2 are the power
supply and the rest are varied between bad controls, horiz or vert sections, or
cheap digital touch controls.
Power transistors tend to be a pain in the tush too.
Sounds a lot
like a bad flyback transformer, getting ready to die. Anyway,
Flickering could be due to the flyback, could be due to a lot of other
things. A missing colour is certainly not the flyback, though.
