Question about Televison & Video
If this is a tube set--and it sounds like it it--it likely needs convergence chips. IF the color and picture was ok before this happened--it is worth a look, but if it was getting dull and fuzzy, BEFORE the convergence problem--it needs tubes and is NOT worth repair.

You need to replace both convergence ICs they are STK392-120 this is an easy repair that you can do yourself and save yourself around 400.00 for about 45 minutes work. You can order the new ICs at the following link and they provide free installation instructions with pictures and also free online support with a support tech while you do the repair. I am one of their support techs. You would also want to order at least 4 convergence resistors and they send the proper ones for your model as often a couple resistors go. Your model uses 6.8ohm 2watt 5% metal film resistors. So to recap you will need (2) STK392-120 Convergence ICs and (4) Convergence ICs . very inexspensive repair if you do it yourself. here is the link.

This is called convergence board failure. try to re calibrate the convergence. if the re calibration fails, this means your convergence board will need to be replaced or, rebuilt.
