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

that's from a thermal switch, to keep the innards cool, post use. Seems to me that you might just check to see that all vents are open and clear of debris, for starters.

Samsung model HLP4663WX/XAA with loud buzzing noise, need to know which part to replace.


See attached photo: you have a bad color wheel----it turns at about 12,000 rpm and bearings in the tiny motor go bad.

High pitched or fan like sound is classic symptom.

The wheel is available on the internet and You Tube has video instructions by model number for replacing it---Google the model number for the part number for your set to locate the part and instructions.

This for most people is a do it yourself job---takes like 45 minutes start to finish.

If color wheel slows too much set will shut down as its speed is monitored and the wheel can even shatter causing shutdown of the set.

HLP4663wx/xaa Fan or Color wheel making noise? I first noticed it within the last week making noise when turning the set off. Now it's continuous. Could hear it slowing down on power off, constant...


A fan like noise is 98% of the time the color wheel.

Wheel turns at over 12,000 rpm and common failure is "fan like sound or even grinding sound".

When these sets first came out if the high pitched sound started women who have better hearing in that range usually hear it first.

If wheel really fails it will shatter and set will not come on----a grinding sound may be noticed just before total failure.

Hi - I'm looking for help with a Samsung Projection TV, HLP6163WX/XAA. we are hearing a noise, possibly an issue with the fan.


most likely the fan like or high pitched sound is the color wheel which is very common in this model;

if it goes totally bad the set will shut down (wheel can shatter inside).

My experience tells me women (who have better high end hearing range} usually notice or hear it first.

see attached photo of part.

There are do it yourself video clips on You Tube showing how to replace it and if you GOOGLE the model number with the words color wheel you will find them for sale. Suburban Electronics is a good source for this part.

Samsung HLP4663WX/XAA picture went out, started making strange noise, all lights on power button came on.


Sounds likea bad color wheel to me, or possibly a lamp has blown. If the noise is a humming sound--it is the CW--if you hear a "sound like a sizzle, for a few seconds and then normal, and this repeats a few times--the lamp has blown.

This TV is horrible. I have the same one and not even a year replaced the light bulb twice. Very disappointing for a Samsung.
