High pitch motor like noise. Not from fans.

1. Check if the fridge is level. If not, adjust the leveling legs.
2. Verify that the condenser coils are clean and free of obstructions.
3. Check the temperature settings and adjust if needed.
4. Ensure that the evaporator fan is working properly and not obstructed.
5. Check the condenser fan for proper operation.
6. If the high-pitched noise persists, it could be a sign of a failed fan motor or other mechanical issue, and a professional repair may be necessary.

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.

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.

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.

the bearings in the motor are going bad. you probably need a new fan motor.

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.

you need to post who made it and model number, is the set a "DLP" ? if so the noise is coming from the color wheel, the bearings are failing, 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.

noisycoil- idetify the coil and remove it.coat it with laquer suitable for motor winding, reinstall after dry.

How deep do you want to get into this?It sounds like the wash pump motor bearings that are worn.You can pull the unit out flip it over and wd40 the bearings in the motor or you can replace the bearings.Try to lube them first.
