Question about LG RZ-37LZ30 37 in. LCD Television

1 Answer

Sound problem Hi, I'm having trouble with the sound on my TV. It seems to have a high pitch background noise that has been getting progressively worse. The noise is even there when the TV is on mute. I've had it just over a year and this noise wasn't there when I first had it. It has moved house so not sure if it's a connection problem. Hope you can help as this noise is getting really annoying! Thanks

Hi: My Magnavox flat screen turns on and off. It also makes a high pitch noise and then there is no sound and it also shuts off. Is it worth fixing?

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.

Hd tv makes a hjgh pitched sound whats wrong

Hi, the high pitched sound is coming from the coils or transformers on the power supply.
you can isolate the noise by removing the back and with the set on press gently with a plastic handle/item on each coil till you stop the noise. , you will probably have to replace the coil or the whole power supply, but sometimes you can tilt it over or secure it with silicone and it will stop rimging.
please click a thumbs up it this helps solve your problem
