Ok so my golden tees monitor is jumpy. It looks like the screen will shrink vetically for a second and then goes back to normal. Will a fresh recap and new flyback fix this? (ive already have the flyback so it wouldnt be an issue)
Almost certainly a cap issue. Flybacks either work, or they don't.
I was working on a Ducksan monitor a few years back that had one tiny little cap...22uf @ 350V, IIRC, in the power supply section...it was no good. That tiny little cap made it so you couldn't turn up the brightness too high, otherwise the picture would shrink - a lot.
