Question about RCA P46921 46" Rear Projection Television
I have an intermittent high pitch squeal coming from the back of the TV. I can change the pitch by manipulating the area where the cable enters the back of the TV. It's not the cable, it the part of the TV where the cable and A/V cables attach. It is very loud and getting worse. TV is around 7 years old. Plan on upgrading to LCD, but would still like to keep this for the basement.
What an RCA I hope you didn't pay mutch for this, NO it's not the part of the board were the cable goes in, the so call squeal is the horizontal oscilation of the coil you hear, narmaly it is at the rate of 15747 hz, to find your problem you most open the back cover, and while the ptv is on try to hear by insolating the noise were it is comming from with a credit car or something that will hide the section you trying to find, it will be a transformer or a coil, close to the power supply or the horizontal defflection section. To fix your problem well that's all a different game, you must contact me via e mail at email@example.com
I hope this help.
Meanwhile keep on smilling, life to short
