Question about Flat Panel Televisions
Turns on great pic. but has a high pitched noise to it. TV 2 and a half years old. Is it worth fixing.
SOURCE: High pitch noise
Hello there, You have to specify where the noise is coming from. Is it coming from the speaker or from the back of the unit. SMPS power supply powering your unit create this kind of noise when some capacitor gone out of their value.

how old is your plasma TV? try check the switch / volume of the sound settings.. Sometimes, when you always increase the volume, it will tend to alter the limit of sound and causing the sound to provide sound undesiredness. I suggest to check it with a liscensed technician.

Hello, what's the model or size of screen for the magnavox, the high pitch noise could be an audio power amp starting to get intermittent, and the power on/off could be due to the over current sensor circuit detecting the audio problem. Depending on the model number you would have a seperate power, audio and signal board in the TV. If he TV is 27" or smaller all these circuits are part of a mother board.
