It is the color wheel. A very common problem with these light engines. I would suggest you to call in a tech to handle this repair.

Hello Jack,

That buzzing might be two things. It could be the color wheel or the ballast for the bulb. To check this you will have to move the projection section of the TV out of the case and listen for the sound in the area of the color wheel and the ballast. Try removing the color wheel power to see if the buzzing stops if it does then it's the color wheel is not and the ballast is buzzing then It's the ballast, and it will need replacing or if you know electronics you could try fixing the old ballast (I would suggest getting a new ballast).

Better still if you are uncomfortable working on the set you could get a qualified TV repair person to repair your TV .

I hope this helps,
Thank you,

When TV is turned on the picture has become darker. This has been going on for a few days and its getting worse.


This sure sounds like a bad lamp. If it is over 3 years old change it.
Also, listen for loud buzzing sounds that may indicate a bad color wheel.
But this definitely sounds like a lamp that is about to go bad.

Hello.
It looks like you ignored lamp replacement in your TV. It have to be replaced every 2.5 years of average use. It's like oil change in a car. Regular scheduled service.
You can read info about lamp replacement in your TV owner's manual, buy lamp on-line and replace it by yourself to save some money.
Regards.

Problem with Toshiba DLP Projection TV Model #52HM84


It is possible the lamps may be defective or that they may be the wrong replacement for this model, as it may have a different wattage setup with the ballast. If you want to try to order the TB25 lamp from a different vendor, you can order the original Toshiba replacement lamp for this model (52HM84) from a major Toshiba parts distributor at the link below:

After much research, it became apparent that the most logical culprit after the lamp was the color wheel. It has been replaced and the set is working again.

Loud cracking sound, and now, nothing


Hopefully its only the lamp. Inspect lamp for breakage. Lamp power supply ok??. Check any air vents (filters if any) before replacing. Lamp life is only a few thousand hours, easy to do in a year, 5-6hrs a day. Check your manual.
