Buzzing noise coming from my speakers....

It just started about 2 days ago for no apparent reason and the only way I can seem to get it to stop is to mute the audio on the unit. I have attempted to change the sound configuration settings (balance, treble, bass, SRS WOW) but nothing seems to work. Any ideas?

Re: Buzzing noise coming from my speakers....

I just did this last week, i had the same problem all you have to do is grab some speaker wire and wrap it arround the RCA's(around the metal or gold piece outside the RCA) that go to your voice AMP and then ground the speaker wire(the one you wraped the rca's with). this will work. NO Noise filter will work cus I tried it

Re: Buzzing noise coming from my speakers....

If you are using a cable box your sound on that or on the tv is too high and causes feed back.  Adjust both sound volums or better yet turn down the sound on the cable box all the way down.and just use the sond control on the tv

Panasonic vt50 humming from the back , is it fans?

Yours is a common problem that Panasonic seems to ignore. The humming apparently comes from the speakers built into the system. The only solution that I know of is to install anti-distortion speakers that have solved the problem for others.

However, before spending any money, I suggest you take a look at a website that explores some of the actions of others. CLICK HERE

What is the buzzing noise coming from the back of the tv when turned on one for minute or two then stops, and over and overf

Does the sound seem to be coming from the right rear of the set? It could be the inverter board is arcing when trying to turn on the backlights, likely a bad solder connection on one of the transformers (a very common problem) This would sound like a buzzing, or a arcing sound. If it is coming from the speakers it could be a power supply problem.

If it is a buzzing noise, it is the Ballast for the lamp.
If it is more of a grinding sound, it is the Color Wheel motor.
Does it go away when you turn off the tv? If so, does it stop abruptly or does the sound tend to get softer (winding down noise)
If the noise stops abruptly it is probably the Ballast.
If the noise takes several seconds and seems to get softer until it stops about 30 sec later then it is the color wheel motor.

Weird, annoying noise every so often

Is this happening on just on input?

If so... Check your connections. If you are using the component cables, make sure you haven't plugged the right audio into the red video input. it's a common mistake. I see it all the time.

If this is happening on all inputs, be sure the noise is coming from the speakers. Then replace the main board.

Vizio speakers make a buzzing noise

It's not the speakers. I usually hear of this problem when hooked up to an HD cable box. You can adjust the volume on the cable box and also on the TV. I'll bet you don't have this problem when watching a DVD.

If the problem is what I think it is, your HD Cable box is set at a really low volume while your TV is set to a rather high volume. Try setting the TV volume to around one-third, then set the volume on the cable box until it's as loud as you'd ever want to hear it. With the TV at such a high volume, you're actually amplifying any stray electronic signals that the wires might be picking up, and the above solution will fix that.

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.
