Loud humming or high pitch buzzing noise coming from my rca dlp tv 50 inch

High pitch buzzing occurs after tv has been on for an hour or so. Noise periodically happens for about 3-4 seconds and then stops. It happens every 20-30 seconds or so. Then sometimes I can cut my tv on and I never hear the buzzing noise when watching it. Noise was not heard until now. Purchase tv about 1 year ago and noise was not there. This is the only problem I get. Picture is fine.

Re: Loud humming or high pitch buzzing noise coming from...

I have a very high pitched sound and when I move the tv it will stop for a second or two and then start again. The sound sometimes stops all together. But very high pitch sound.

Re: Loud humming or high pitch buzzing noise coming from...

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.

Have you moved the TV or installed any equipment in your house, or started using an Air Conditioner, fluoro light etc?

A high pitch sound can be a capacitor losing power it would sound a bit like a fire work. most have back up on the board but it put more pressure on them the more times you use the tv. would check them and replace. all of them can be 5 in a row in some models.

If its a DLP with a high pitched or even fan like sound it is the color wheel--Mitsubishi does not sell them as a part---you would have to replace the entire light engine (expensive and may not be available any more on a older set) .

I have Samsung DLP TV 50 inch HL-P5063W

First thing to look at is the color wheel this model uses--usually it will make a high pitched fan like sound but can make a grinding sound also.

If it slows down from the 12,000 or so RPM speed it will cause color issues.

Samsung BP96-01579A Color Wheelno the fans will not produce a high pitched noise. they will ususally produce a dull noise because they dont spin anywhere near as fast as the color wheel. the color wheel will start up before you see video and stay on for few moments after power down. if the fans were faulty the tv would give you message on screen.

I have a humming noise coming from my 5 year old samsung 50 inch dlp tv , I have replaced the lamp 6 months ago so what else couyld the noise be coming from? I have a great picture and color.

If it is a high pitched whine it is most likely the color wheel; the bearings in the wheel go bad and if you google the model number with color wheel you will find it.

The whine is the early stages of the wheel failing; when it goes out you will either have shutdown or a grinding sound.

Let me know if you have questions as I am here to help.
