Is this a DLP or LCD projector?

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.

It could be a bad lamp but I've run into many of these TVs with bad color wheel assemblies. Also, if you are getting a dialog box coming up with these words," airflow blocked, TV will shutdown ..." that's a defective thermal fuse.

This is a job for a mitsubishi authorized service center. A tech can disassemble the light engine and confirm that the wheel is the problem. If you're still in warranty, great. If you're only recently out of warranty, call mitsubishi for assistance. Remember that persistance pays off when dealing with large corporations. You very seldom get what you're looking for on the first call or from the first person you speak to.

Here's something that might also be useful. After you turn on the set, and get the regular red blinky lights, hold down the Device and Menu buttons together for about 5 seconds.
The Power light will start to flash in a two digit sequence.

For example, 3 flashes, then 7 flashes = 37.

Here are the error codes, and the corresponding problem:

12 = No error detected, check power supply.
32 = Lamp Cover is open.
33 = Air filter cover is open.
34 = Lamp abnormality
36 = Light Engine (DMD or Lamp Fan stopped)
37 = Exhaust or Lamp Ballast Fan stopped
38 = Lamp Temperature High
39 = DMD Temperature High
41 = Short is detected
44 = DVI cable between FMT and Engine disconnected

the light engine is defective and needs to be changed..this set is not that old..contact mitsubishi customer relations to see about having it done under a customer accomodation, as they have had a lot of problems with the engines
