If by a color split, it looks like a 3-D picture, the problem is in the convergence circuit. Since it recovers on its own, it suggests to me that there is a poor solder connection at the convergence ICs. If you can solder, this should be a simple repair. Locate the convergence ICs (large black ICs attached to a heat sink that should be marked STKxxx). Resolder the pins on both ICs. If that does not resolve the problem, let me know.

    You will recognize the heat sink as it is a large silver colored metal piece with a couple of black ICs attached. There are high voltages present even when the set is unplugged, so be careful. You should be fine as long as you are careful not to touch the picture tubes or the red wires going to them

2 possibilities. Either your convergence IC's are going bad, or you need to remove the front panel of TV where the speaker grill is and you will find a small box with 6 control knobs on it. Mark each knob so you can set it back to its original position if you forget, the set might turn off if you adjust too high on either color, if so, set knob back in original position and turn tv back on and try again.The if it works reallign your convergence and that should do it.

Colr red keeps coming in and out. had tv for 5 years and hasnt been serviced


If you don't have a degree on tv repair you should not try to fix it yourself, projection tv's are complicated on the way they are build, and when it comes to realigning the projector you are better of leaving it to the experts, dont try to fix it you might make it worst.

Color wheel


as a technician i dont feel the color wheel is a difficult repair. HOWEVER ..color wheel relacement means sometimes depending on model removal of light engine. which means you can get into alignment issues. then once the color wheel is replaced then it too has to be alligned.

3 green spots on the top center of my projection hd tv


I had a similar problem and brought it in to a technician for a quote of $860 to fix. The problem - speck of dust on the optics. If it weren't under warranty I would take it apart and blow off the dust myself.
