Question about RCA HD52W56 52" Rear Projection HDTV
Hello, I have a TV that is a little less than 3 yrs old. It's a 52" RCA rear projection with HDTV and just recently it started making this high pitch noise. At first it has one or two second long beeps, then it goes to a more consistent high pitch beep or noise. I've turned off everything (cable box, DVD player, etc. and it doesn't stop. I listened and think it is coming from the back of the TV. If I whack it a few times it stops (but that's hardly a cure for the problem). Any idea what it could be and what I can do to fix it?
I think it is the color wheel
