Did you attempt to repair your computer on your own and then started to have this problem or did this just suddenly happen? Also, can you post a picture of what you are seeing?

Probably the projection guns (my JVC had them fail on me). It started that way and eventually I had a triple image of what was on TV, one in red, one blue, one yellow, and all slightly offset from each other. The fix was new projection guns (thankfully it was under warranty as they were about $300 each).

Your tv has a convergence board problem. Have a technician replace the convergence IC's.

There are two convergence IC's that are bad and need to be replaced, as this happens to almost every rear projectionj set ever made. They are stand up IC's , on a heatsink and they start with STK. They are soldered into place and this set has no user replaceable parts inside of it. If you have no solid state repair experience, you really should call out a trained tech to assist you in this repair. A TV set is no place to be diggin and experimenting inside of.

The problem called Convergence problem. Unfortunately, some sets have manual convergence boards - which means you can do nothing but replace it and adjust the manual controls on the board itself. But some of the newer ones (Maybe yours) can be accessed through a service mode. So, give it a try and look for a service mode in your set... Good luck!
