It sounds like the picture is rolling. Unfortainatly, there is no vertical hold in this unit, and therefore theres a vertical sync problem. It could be a capacitor, as i've seen this in other sets or something in the sync separator circuit. Since this set has no user serviceable parts inside this set, your gonna have to seek out a pro tech to assit you with this repair. Theres no board to swap out in this model and would cost to much to do this. Good Luck
