One of your convergence IC's has either cracked loose or burned out. The IC will have to be resoldered or replaced and then the convergence circuits realigned. If you do not have experience in repairing convergence circuits then have a qualified tech handle it for you. This is by far the most common failure in the projection sets and a good tech can have it fixed in about an hour and a half. I charge $150 for that but shops in your area will vary, so call around.

Good Day, Techwanab;
Look for this to be your problem: CHECK FOR OPEN L2C50 PART #325C146030 ON THE SIGNAL PCB, OR BAD CONNECTIONS AND LEAKY CAPS IN THAT AREA.
Hope this was helpful and not too late.
Good Luck, big IRISH.

You have a bad ground on a convergence IC. You will have to carefully pull this board out and resolder the pins. If this does not solve the problem you will have to replace the ICs. I have saved a few of these TVs with just a resolder job. Thanks for asking!
