Question about JVC AV-30W475 30" TV

1 Answer

Loud Buzzing Noise

Recently my JVC TV began buzzing very loudly. I tried adjusting the sound settings, along with doing a brightness test to see if it was a coil responding to AC current. Lessening the brightness and changing the settings hasn't worked. When I mute the TV, the buzzing drops about 50%. It seems to be getting worse daily. Can someone please shed some light on what is causing the buzzing? Thanks so much to whomever can help!
