I think the fan is making high pitch noise in our Samsung Dlp

The color wheel is the most common problem when it comes to noise from DLP's. To determine if it is a color wheel or fan: Turn on the set. When the noise starts, turn off the set. If the noise goes away within 5 seconds, then the color wheel is bad. If the noise goes away after one to one and a half minutes after the set was shut off, then one of the fans are making the noise.

krugie, get it replaced now or the lamp will burn up, be advised that they are expensive to get replaced, not an easy job to do, fix it now or pay much more later is the best advice I can give you, good luck, BMW Rider

The high-pitched noise you are hearing is the color wheel. It is a very common problem in Samsungs.

The problem is the dust that has hit the fans. The light and color wheel. In short DLP runs hot and if you have dust forget it! if you have ever sat in a presentation the projector is DLP. You can try to clean it out but there is not much you can do. I have a 61 inch RCA and it drives me nuts.

You will have to pull out the light engine. That will consist of 4 or more screws and disconnecting some plugs. The the whole unit slides out where you can get to the fan housing.

Unless you're mechanically inclined, you should not try it as you could damage the assembly.

I don't know the part number off hand and some of those have newer part numbers as replacement for the original. Just do a google search to come up with a part number.
