Question about Mitsubishi WD-73732 73" Television

Color fades out on tv

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.

Colors have a blue-green tint


Try this first:

Press: MENU, 2, 4, 7, 0, ENTER

This will factory reset your tv. Be aware, this will erase any NetCommand or user-created features you have set up on the tv.

Check your results.

If you don't see a change, begin to suspect either the lamp, color wheel or light engine.

Lamp light turns red


Yes this is the signal for a bad lamp. Other things can cause this. 1. Look at the new lamp. make sure it still looks good. not broken with little glass pieaces in it. 2. When you turn on the tv, put your ear to the lower back part of the tv near the middle. Listen for the start up of the color wheel (a low high pitch sound only at the start up of the motor). If this is good you will here a ticking sound only if the lamp dose not light.

Now with all this info. If the lamp lights (as seen from the back of the set) and goes out after a few seconds and you did not here the color wheel spin up, the color wheel is bad.

If you here the color wheel spin up and no ticking sound, the Ballast is bad.

The ballast part no. 939P978010

The color wheel is not avialable from Mits. You will have to replaced the light engine. It cost to much. Just buy a new tv.
