It means that the color wheel or it's encoder is not properly syncing with the controller. It is therefore blanking the DLP chip on the red and blue sections of the color wheel. Clean the color wheel motor and encoder disk, lubricate the motor. This should correct the problem. There may be dirt in the opto-coupler that is reading the color wheel. Be sure to clean it with a vacuum and small brush. Regards.
Don't know the exact problem, but typical projection tv's get very dirty and this may affect picture clarity, contrast, and perhaps color, including overheating of components. Make sure you have good airflow, clean filters, and a projection lamp that is free of contamination and finger prints. If you have a setup function, check the colors for purity and integrity
my mitsubishi 73" set is 4+ years old. all of a sudden the color is all wrong. after a couple of minutes of clear picture the colors change--blue is green and red is yellow. a little while later everything has a red tint to it and there is a line going down the center of the screen. to the left the picture is still relatively sharp, but the right hand side is terrible. I'm hoping this is just the lamp.
You are missing either red drive signal to CRT or you have a cold / fractured solder joint on the television. Also with the set unplugged check with a non metalic object like a ruler or a wooden spoon and start tapping around in the front or back of set and see what happens. See if you can narrow which area of the set has a problem... Good luck future technician.. Happy holidays.. Jay
Your color wheel is bad. Thats the only thig that controls color on the DLP projections. You will need to replace it But I would check the connections on it first to make sure the connections are secure. Let me know if you require more assistance.
