Mine has the buzzing. I even created this current one out of 2 damaged ones, the original internals did it as do the internals I took out the "new" one I got (it had a smashed screen). I noticed it stops completely when muted, but not when the volume is on 0. It also gets louder when the contrast is higher (just flick between the preset PICTURE MODE's). I think it's something to do with the internal speaker cables perhaps running too close to the display circuit or whatever (Im not sure what causes it, its normally electrical interferance being picked up by an unshielded cable). I'll no doubt get hacked off and reopen it soon to look about. I'll post back when I do, may be a few months though!

Hi there I have had the Tv for 5 years and it's


I would first check any of your inputs (i.e. cable, satellite, DVD player, ect...). If you hear this buzzing sound regardless of what input you are using, then it has to be the TV. If it's the TV causing it, audio is produced on the main board or A board named by Panasonic. It is the board that has the A/V inputs on it (cable, HDMI, component). This model has 2 different main boards it could use either TNPH0721ACS or TNPH0721ATS. As a TV repair technician, I often use Tri-State Module and would recommend them for parts. If you don't know which board you need, their customer service is helpful. I hope that helps.

Try another input and another source such as a DVD player. If you still get the buzzing sound, you could have a faulty power supply output or a fault in the audio circuit of the main board.

I recently bought a Vizio television Model Number Vizio e370vl and I have been experiencing a buzzing background noise whenever I have sound coming through the tv speakers. Be it my satellite reciever...


Exact same problem, buzz was not overwhelming but non theless there. Tried antenna, dish, dvd, another persons house and buzz remained.Complained to Vizio, tech cam out and replaced mainboard I think it was. Bahm,its fixed. Would have tried returning to Walmart but figured another new onemight buzz as well. Tell support line you always have the buzz no matter whatthe input (dish, antenna, dvd player). Windings in power supply coils have air gapsthat create the buzz I read somewhere. Good Luck

Vizio Speaker Making a Buzzing Noise


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.

Very loud fan or vibration noise


Listen from the back of the TV and locate the source of the noise. There may be fan with a bad bearing. The noise will lead you to it.
