Television buzzing noise

This is a power supply and/or possibly inverter(s) board bad capacitors. Since the audio is affected it could be both. Be aware that attempting to repair it yourself could cause irreparable damage to your TV.

You may have blown your right speaker if you max the sound allot, you may need to replace. Hope this helps- Pleas comment

maybe just poor speakers.....had a similar problem with an old sony. Replaced the speakers twice and always had a noticeable buzzing. Try running external speakers (computer speakers will work) at low volume to see if you hear it in those. If so, you may have sound board issue.

It ur Vizio tv,The power supply board is the problems.The transformers in the power supply board have gaps in the transformers.The high voltage curents flow that make that buzzing noise.

check where your pluging the red sounds like your pluging a video signal into an audio jack or your red cable ha an open ground

When we turn our TV the humming and buzzing begins! We cn mute it and it goes away and then it when we turn the sound back on the sound is back! How can we fix this?

Watching a movie tonight...and slowly there was odd behavior from the screen. No volume at first, then flickering, fragmenting and now, as the others only shows the red power. I have noticed some strange flickering the past 2 weeks or so. I thought it may be the cable, so did not concern myself too much. I believed that was the problem tonight as well. But the screen is definately not responding to the remote or manual button.

Thanks

You maybe be able to turn the internal speakers off through the tv's menu...either in the Audio section or in Settings

My 32" vizio I bought a week ago does the same things.

Buy an external sound system for the tv. Turn the speakers off in the TV menu. Hook the sound system up to the out speaker hookups on the tv.

You will not only have better found, you will fix the speaker buzz problem.

Your problem could be the main amp board, the signal panel or the audio processor board. You will need to get a service manual for this set to diagnoise these problems. Good Luck
