SAMSUNG HLR4667WX/XAA Buzzing sound - iNTERMITTENT

Its sounds like a fan blade is lightly brushing something like its wiring or housing, possibly worn out bushingson fan shaft. I removed back panel and held the safety switch in and turned it on then checked the two fans that are visible without further dis-assembly - these two seem to be OK . The fan or whatever is making the spinning /buzzing noise is out of direct view.

It sounds like you have a bad color wheel--it will give a fan like noise before it fails--some describe it as a high pitched whine--if it shattered the set will shut down. It faces the lamp for your set--about 2 inch in diameter with colored segments colored like a pie--this model uses 2 different wheels--label on side of set will give full model number and version number---part is about 130 on Ebay and it requires the light engine to be removed to replace it--takes about 40 minutes--I have seen dozens of these with this problem--you can research it by taking the model number and Google it--lots of sites have general instructions for replacing it---I get lots of them local where someone buys the color wheel and has me come out and replace it(I usually charge 100 for trip and labor to replace it) bottom line is a shop will try to charge you 400 for this repair---but if you can buy it and find someone to do the labor you can repair the set for a reasonable price.

Have you had a issue where you heard a high pitched whine or fan like sound?

Examine the color wheel- can be done with lamp removed--look in the opening the lamp faces---is wheel intact or missing any pieces?

The set will turn lamp on for a instant and then off if it detects wheel not moving at full speed or not at all.

This is something that cannot be easily guessed at. There may be a failure in part of the power supply, and on one of the processor boards.

You will have to have the Samsung service rep do the necessary repairs on your set.
