Hi all,
Appear to have some 60Hz noise on the video signal - not on the audio.
It appears as a series of white lines (spaced by about 10 lines) moving
slowly up the screen.

I think this is probably a bypassing capacitor, but don't know where to
start looking. I haven't cracked the case open yet, because the TV is
in high use.

Does anyone have suggestions and/or a schematic that I can get a hold
of?

Any/all help would be great. Thanks
