I have the dreaded buzzing noise and no picture. Would a broken color wheel alone cause this or do i need to replace the bulb as well?

The buzzing noise is usually related to just the color wheel for your model.

My samsung 42 inch hdtv is making a buzzing noise


First. The whirring or buzzing sound you hear is the Color Wheel and it needs to be replaced. Second, since I do not know when and if the original lamp has been replaced it is a good idea to replaced the lamp. The bad Color Wheel is the one causing the set to shut down.

Our Mitsubishi WD52525 52" is making a loud buzzing sound. could this be a fan not functioning? We do not have a picture, but have recently replaced the bulb.


This sounds to me like it could be the color wheel or the ballast of the unit. The bulb is always the first step, but it depends on what kind of buzzing you're hearing. The ballast will usually click to ignite the lamp, while it may also buzz when it's not functioning. The color wheel will also buzz if it gets stuck, or rattle when pieces inside are broken.

Screen went B&W and I hear a loud humming noise from the TV...


Hi John,

If you are hearing this noises,that's your Color Wheel.
The reason fot that is because your color wheel spins 5000rpms(revolution per minute) and something that modifies the balance if the disc can cause different things.Unfortunately in order to check if your color wheel is working properly you need to open your TV and physically check out.

Grinding= Most probably the color disc is broken and you need to replace it.

Spinning / Buzzing = The bearing of the wheel is loose and is loosing its balance,eventually it will brake.

The best thing to do is to take the color wheel out and spin it ,if you feel that the disc kind of wobbles or doesn't spin smoothly you have to replace it.

You can check DM they have very good prices
