Why Is My LCD TV Humming?

Last Update Date : Apr 06. 2018

In general, LCD TVs do not hum.
If your TV is humming, and the sound appears to be coming from the speakers (that is, it gets louder or softer when you change the volume),

If, however, your LCD TV is making a high pitched whistle, hum, or squeal, and the sound does not go away even when you turn down or mute the volume, then most likely there is a problem with the power supply in the TV, and you need to get the TV serviced.
