High pitch motor like noise. Not from fans.

High pitch noise near lamp and fans. I checked the fans and lamp, they are working fine. Could it be some other motor/component?

Samsung dlp tv HLP5663W makes loud noise


Yes, the set uses a color wheel and the lamp faces it.

The wheel turns at over 8,000 rpm and is well known for this problem=bearings in the tiny motor go bad.

The high pitched or fan like noise (classic description) is this part.

Sooner or later the wheel (plastic colored segments) will shatter and set will shut down lamp and not operate---set monitors the speed of the wheel so if it slows down or stops it knows.

The part is readily available on the internet (Google the model number with "color wheel").

This can be a do it yourself repair and You Tube has video instructions for replacing the wheel by model number.

There are two common pitfalls to avoid which the instructions that come with the replacement part usually do not mention---if you decide to do this repair let me know and I will explain.

My toshiba mod. 52hm95 lamp cooling fan is making noise and i am having trouble locating a replacement


Fan like noise may be a fan or the color wheel---color wheel spins at high speed(lamp faces it) and when failing you will have a high pitched or fan like sound---hard failure and you will hear a grinding sound.

My samsung HL-S5086W has a high pitched buzz that is present when muted, and continues for 2 or 3 seconds after you power off. Any ideas? I heard if it continues after power is off, then it is a fan, not...


Samsung BP96-01579A Color Wheelno the fans will not produce a high pitched noise. they will ususally produce a dull noise because they dont spin anywhere near as fast as the color wheel. the color wheel will start up before you see video and stay on for few moments after power down. if the fans were faulty the tv would give you message on screen.

High pitch noise from the projector and is not from the fans


it's the colorwheel. if you have an infocus x1a, it is a dlp projector and has a colorwheel and dmd chip instead of 3 lcd panels. the colorwheel spins to allow the lamp to stike. it should make a slight high-pitched squeal. if it's too loud, the motor is shot and needs replacing.

Hi, bearings in color wheel are about to fail, get it fixed now before the wheel shatters the prisms all over the inside of the tv which of course will then cost you more to fix, video-tek

I don't think they can be, but, also take a look at the fan bearing assembly too. You should be able to isolate if the noise is from the motor bearings or blower bearings.
