let me know if thats works for ya

Mits has had an excessive number of problems with color wheels in some of their optical engines. Provided you replaced the lamp with OEM parts I would suspect the color wheel is causing the noise as well as the shutdown issues.

I have the same problem with a WD 73732. After about an hour fleshtones go blue / purple, and picture flashes. I gutted the set, and ran it on the bench, and found that a sensor on the color wheel (a small external board), acts up when it gets hot. Cooling the board fixed the picture. I'm going to try to find a replacement part, and then make vents in the color wheel cover so it doesn't get so hot in there.

This would be the little sensor on the light wheel. Its cheap, you can get them online for around $2. You will need to take the light engine out and remove the color wheel cover and remove the color wheel and then remove the sensor. You will have to desolder the sensor and remove it to replace with the new one.
What is happening is the sensor is overheating and not tracking the color wheel properly there for the colors get messed up. Once you replace the sensor the tv should work like normal. The part is
(Sharp GP2S40 Photointerrupter). It is very difficult to find because they are not made anymore. Most major online part stores do not carry them but I found a lot of them at Wright Hobbies. Good luck.

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.

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.

That load sound could be the color wheel . But first check your lamp that could be bad. and if that noise you here sounds like something taping it could be color wheel which would be bad mit only sell complete light engines cost os 650.00.

But hopefully you will get lucky and only be your lamp.

Thanks doctor video

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.
