We have a Mitsubushi WD-73732 73 inch tv. We recently had the lamp to go out and I replaced it with a new one. Last week the tv started acting up. It will play fine for a while and then the colors blink out and it has a greenish tint picture all over the screen. Then, it may stay that way for a while, or it may blink back to a normal color picure. Can you tell me what's going on?? Thanks !

I have the same tv and the same problem (color banding, incorrect colors, colors blinking) occured after I replaced the lamp. I had a tv repairman take a look at my unit and he said the color index was incorrect, the tv doesn't know the correct colors to display. The best way to fix that problem is to replace the "light engine". The repairman replaced the "light engine" to my tv and everything is working great. My tv was still until warrenty so I don't know how much a new "light engine" would have cost.
Sounds like your color wheel may be at fault. Do you ever hear any unusual noises coming from the rear of the TV? Color Wheels usually make a humming sound as they go bad. This is because the tiny bearings in the color wheel motor have begun to misshape from use and heat. Your TV may have a new type color wheel assy that has a slightly different configuration but the result is the same.

We have the exact same problem. Our lamp went out about a month ago and now the color fades out. Does anyone have a solution???
