    Tv is making a high pitch noise

  • janinegilroy Mar 06, 2008

    Hi. I have the same problem with the high pitch noise coming from the side/back of the TV. I will check into the sound controls as I know we have constantly altered the volume. Hope this is an easy fix. Thanks!

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.

Check high voltage circuit. This is near where the 120 volt cord is plugged in and a high voltage transformer, where there should be capacitor (or two). Check the voltage - should be 390 to 400 volts. If not less than 390, near to replace the capacitor.

How do I stop the static noise from my vizio tv?


At high altitudes all plasma tvs will emit a high pitch noise.
There's nothing you can do about it besides move or get a new tv. Plasmas just do this.

Hello, I own an LG42PCSD,good picture, but, i am


Sometimes the transformer on the Z-Sustain board can vibrate & give off a high pitch noise or hum, or the tranformers on the power supply, I've even known the plasma screen itself to cause a hum. The best remedy is to try & locate exactly the area of the hum to pin point which board is the cause & then replace the board or if it is the screen, then it is more economical to try & put up with the noise rather than replace the screen.
