You almost certainly have a dried out capacitor in the vertical
deflection amplifier. Just a guess but I bet it's 1000 to 2200 uF
very near the vertical amp. This happens all the time with Sony
CRT monitors.

Thanks, G², greatly appreciated!



Check the vertical deflection driver if new caps (use good quality 105C
ones of course!) don't fix the problem.

Use low ESR caps for anything on the horizontal circuit, check the other
electrolytic caps using an ESR meter like the blue Bob Robert ESR meter
kit one that we sell.

We've also replaced a lot of the associated deflection transistors in
vertical circuits when the cap failed...
