You are going to need a schematic---the sync pulse either comes on a line from the high voltage transformer or the Jungle chip---my money would be a open resistor from the Flyback with that pulse for sync.

PROBLEMS WITH VERTICAL ROLL


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

Vertical rolling


Does you set have PIP (picture in picture)? If it does then the PIP module has a bunch of capacitors that have gone bad (dried out and leaked) causing you to loose vertical sync. Vertical synchronization is what locks your picture keeping it from rolling. Even if you don't have PIP then still you have a vertical sync problem. The set would have to be checked by a tech to find exactly what's happening. Stargazer

Picture keeps rolling


The picture rolling is simply because the PAL decoder can't lock up to the 60Hz vertical sync pulses, even if your DVD player is set to NTSC-PAL conversion and there is no vertical hold adjustment (either external or internal) on this model set to achieve this. There is a possible alternative only if your DVD player has RGB output (not component). The JVC for example has direct RGB drive capability via the SCART input on the back panel. If you get a suitable lead you could try getting a picture this way as it bypasses the decoding and sync sep circuits in the PAL decoder chip.
