Color wheel noise on Mitsubishi WD-60735

I have owned two DLP's to date and both have given me problems with the color wheel. I have tried several solutions to try to quick fix this. First I did a system reset and the noise was cut in half. Then I unplugged the set for two minutes, plugged it back in and held the guide and menu buttons down to run a self diagnostic. It found an issue with the color wheel, and self calibrated for the problem. The whinning is barely noticable now, but how long before it becomes unbearable again? I have a MASSIVE home theater with VERY HIGH decibles of ULTRA low freq bass. Could this be contributing to my color wheel problems? And could it be the cause of my unusually short bulb life?

    I am having the exact same problem. Are you able to provide me with a bit more detail on how you did the self diagnostic test. I can't get my set to do it. Can you give me a step by step instruction? I would greatly appreciate it.

You need to replace the "light engine". This is very very difficult. You need to take it to a repair shop. But this will be very expensive. Around $1,000.00

If the green front panel LED blinks continuously and the TV never comes on, its an issue with the "DM" board. When these TVs are first plugged in, the green LED should blink for 30 sec. to a minute or so. This is the TV booting up, reading its software. Mitsubishi has been having problems with this circuit for several years. In may cases the only permanent solution is to have the chassis rebuilt by Mitsubishi at considerable cost and inconvience. The chassis may have to be sent back to Mits for this rebuild. Call Mits and ask for help.

It's possible that you have a fried diode on the secondary side of one of the power supply transformers. Look for one that reads like a wire on an ohmmeter. Note that some diodes come in TO-220 packages so they look like plastic power transistors. (Don't be fooled by capacitor bleeder resistors - if present, these are in the tens to hundreds of ohms, so this is what you will read instead of the diode if the diode is good.) The whistling noise could be a switching power supply transformer with an overload as a result of the diode, although the primary-side power controller circuit should shut down immediately before letting that happen. It could also be coming from the speakers - that would be a hint to check the power supplies feeding the audio circuits.

If after that you are sure all of the internal cables are connected, especially to the light engine, it's time to start checking voltages and waveforms, beginning with the power supply. You apparently have power to the bulb and color wheel, and probably to some of the control circuits, but that of course is not all of the set. Most sets have some fine print on the power supply circuit board telling you what the voltage outputs are supposed to be.

We just replaced the DLP chip in our mitsubishi 1080P tv because we had white spots all over the screen. Now after replacing the DLP chip we have no picture at all but we have sound. Help?


Likely you either forgot to reattach your color wheel ribbon connector, or have it on upside down. It's the tiny ribbon cable behind your circuit board that will come off as you pull the board away from the DLP chip.

How can you diagnose a failed lamp in a Mitsubishi DLP WD 52631


Remove the lamp and do a visual inspection.
If this is a DLP you may have a bad color wheel! whistling sound is a sign of color wheel.

Good luck to you

Where is the color wheel on 60735


Color wheel if it has one is not sold by itself and the optical engine itself has to be replaced.

My Mitsubishi wd-30765 started to buzz. Then it made a squeeking noise. The indicator light went red. I changed the bulb but this did not help


WD-30765 ???
Please recheck model number as WD-30765 is incorrect/ invalid model number.
Buzz sound could be of bad color wheel in light engine and cause of problem.
Let me know correct model number to diagnose problem in your tv.
Thanks.

You have a Bad Color Wheel Assembly, have optics engine replaced.
Although these parts are seperate, Mitsubshi will not sell them that way.

But here is a site which might be able to help u in obtaining a new or factory refurbished Optics Engine.
