I own a Mitsubishi DLP 52525. I recently turned it on and the color and tint appear to be severely distorted. I've tried adjusting color/tint setting of course...no improvement-just makes it worse.
I thought initially that it might be the colorwheel. However, I tried the PIP/POP function and am able to display the proper color on the alternate tuner used for PIP. Incidently, I can PIP from same device, so I'm able to watch a bad image on the primary tuner, and the correct image on the alternate tuner.
I've tried all setting adjustments (at least I think I have) and even tried to restore factory defaults...No change.
Also tried different devices...still no change-primary tuner has poor color and tint.

the circut that detects the bulb has been also failing in these sets
and the conversion chip that controls the picture , and the transformers are not putting out the full power they are supposed to.
this set will need to be tested to determine the exact cause or causes

If it is Mitsubishi WD-52525 DLP TV then it sounds weak lamp problem in TV and TV needs lamp replacement. How old is this TV and did you replaced lamp recently? Lamp replacement is written in user manual of TV and it is easy work. Please buy Mitsubishi original lamp for TV safety. Thanks.
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.
