Question about Samsung HLP4663W 46" Rear Projection HDTV
When I turn the TV on I hear a noise like a turbine/moaning sound and vibration coming from the back of the TV. It lasts for roughly 30 seconds, stops and then continues one more time before stopping. I've had my Samsumg HLP4663W for 5 years and thought this is a sound when the lamp goes out. I ordered a new lamp, put it in and nothing has changed. Do you know what it is and it it's easily fixed?
The grinding sound that you are hearing is your color wheel. They can make a noise from a buzz to a power saw type of noise. Usually the set will continue to play with the noise, but it is annoying. You will need to replace the color wheel now.
This is not as easy as the lamp replacement, as you have to pull the light engine to access the color wheel. It is not hard just more work and be careful of the color wheel lenses.
I hope this information allows you to resolve this issue.
