Question about Projection Televisions
This is a common problem and is either bad connections at the vertical Ic or a defective IC. Look for a small flat Ic attached to a heat sink with 9 pins or so. It should be marked LA7837 or similar. Resolder the pins and try again. If that fails, replace the chip. That should fix it. You may also need to replace some capacitors in the same circuit if the picture lookes stretched or otherwise off. The Ic should be labeled on the board as ICxyy. Capacitors in the same circuit will have the designation Cxyy. Change the Caps that have the same x designation.
