Re: Vertical Rolling picture

Vertical IC, caps or the hyper board would be my guess. None of which you can do yourself without some serious electronics experience. You'll need to ESR test the caps in the vertical circuit first, then move-on to static testing the vertical IC. If either of these are the problem it's not too expensive. The Hyper Module is a different story, usually only replaceable as a module but you can also send them in for rebuild to PTS Electronics.

This TV needs a service adjustment done. Looks like a vertical or horizontal IC is failing. I'd go ahead, and shut off until services adjustment is made. Have you unplugged for a few minutes and plugged back in? However, I'd have a service tech look at it.

Vertical rolling of picture

If the picture rolls while both on cable as well as when you playback a tape or DVD, it could be caused by a bad filter capacitor in the power supply or vertical deflection circuits. If it only rolls while trying to view a picture from a cable/satellite box, then that component is likely at fault.

That is not a vertical roll from side to side, this is a horizontal rolling. if the vertical had a roll it would be going from top to bottom. This is most likely a coupling between the horizontal sync circuit and the sync separator circuit. Good Luck

This is a problem with the low voltage condition in the main power supply or the sweep supply, or there is bad capacitors in the vertical driver circuit, or the PIP circuit if there is one. the best way to troubleshoot this would be with a schematic, measure all the voltages and see if there are any lower then normal levels. In the vertical and PIP circuits, you will need an ESR type capacitor meter. if you dont own this equipment, or have had no experience working on solid state electronics, play it safe and call in a tech to assist you in this repair. Good Luck Please dont forget to rate this thread.
