Sounds like the cooling fan blades are hitting something (possible worn bearings).

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.

I'm experiencing a loud buzzing (fan?) sound that just started recently while watching my HLP5674W. The picture is fine, but the sound of what may be a fan or something like that is very loud and will...


Loud sound would be coming from defective color wheel that is mounted i light engine, next to lamp housing. Replacement of color wheel is required expertise/ experience and professional will do that for you in correct and in safe manner.
Contact local tv repair shop to get color wheel replaced in tv.
Thanks.

Buzzing sound


I'm no Expert, but I have worked for a major statelite tv company for the past 7 years,one thing you can check besides the channels, would be the video inputs, see if you have the same issues with different components dvd vcr etc.. if so it would be narrowed to the tv or poss connections to the tele..
