Zenith SG5745H9 Again ... Horizontal question

[rwagoner]

Hello ... me again, still with the Zenith Advanced System 3 27" solid state console, model SG5745H9. It uses a 9-959 main board, and a 9-754 Sweep board.

I never got around to fixing the "jumpy" picture because it wasn't a priority, and it seemed to go away either if left on long enough OR if unplugged long enough.

Recently it had been left unplugged for a long time; my son then used it and it worked fine for some video gaming. But he left it plugged in. Today when I turned it on, the picture seems to be showing a horizontal hold problem, but interestingly enough, the on screen menus show fine. Is this a case of "change all the capacitors in one area on one board," or is there something specific I should be looking at? Hopefully it's related to the previous problem and I can finally get it working fine again.

THANK YOU as always. Retirement soon ... will have more time for my old stuff ...
