Call a tech.

To me it sounds as if your convergence Stk chips have blown when this happens its a possibility it took out some resistors and pico fuses too.

I'm no TV repair tech but I fixed 2 TV's that had blown Stk's.
so most likely its the same problem you got.

Not much i can help you with but maybe put you on track to what the problems is called.... search up about TV convergence and try Philips convergence.

Lots of rear projections got this problem do to the chip running extremely hot.

If you can solder and have the equipment to solder you can probably do it your self much cheaper then a repair shop would charge you.
