Question about RCA HDLP50W151 50" Rear Projection HDTV
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.
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.

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.
