    This is no help. All that did was take the static sound out of the buzzing.

    I'm starting from the beginning. It seems that my question was not posted correctly. My Audiovox LCD tv is making buzzing noises on and off when the tv is on. You can not make it stop even when you mute the tv. What is the problem?

    How do you repair the power supply problem?

Ensure that you are using a well shielded cable to connect the tv, try a replacement cable, often that can solve the problem.

Can you provide more details on buzzing sound in your TV?
When you press mute button, buzzing sound still there?
If yes then it seems power supply issue with audio amp section.
Awaiting your comments to proceed further.
Thanks.

The buzzing or humming noise you hear through the speakers is cause by the power supply. The voltage that is running the audio circuitry is low or not filter properly due to failing capacitors.
I repair these power supplies, let me know if you need further assistance or if you decide to the power supply repair.

    The power supply is inside and to get access to it, the back cover and the pedesta stand will have to be removed. Once you locate the power supply look for leaky or bulging capacitors.

    Top class also mentioned a capacitor in the main board that could be defective as well.

Hi!

There is some problem with your remote and not with your tv. If you want the mute button to work then clean the remote internally, or if you are using a universal remote then re-program it.

    That sounds to be bad power supply circuit on youir LCD, get it checked.



    Check if you are using a (3 prong) grounded power socket.



    Please ask for clarifications.



    Thanks

Lg lcd tv buzzing sound


You have problems on the sound portion of your board. It could be a bad solder joint causing it to arc to another component or to ground. It could also be just a plain ole bad Amplifier or something. When you mute it you turn all the voltage off to your AF Amps and naurally the noise will stop. Find the sound board and check it for cold solder joints.

Tv making loud buzzing noise


A common cause are failure of decopling capacitors in the audio section, and or the circuit board power distribution that feeds the audio board. Most of the capacitors are surface mount components. The standard fix is to start by changing the circuit boards that have the defective parts.

If the set is under warranty, call for warranty service. Out of warranty service is expensive for these TV sets.

Loud buzzing noise on vizio tv


It sound like you may have sound processor problem which is part of the main board, I would also look at the 12vdc from power supply to make sure it is clean DC.

Vizio GV42l buzzing


Vizio makes an ok LCD, but if you notice they no longer make plasma. they stopped last year. Anyways. the buzzing sound is semi serious, it sounds as though you have a capacitor leaking. It is best to get it fixed before it goes out all the way, with it buzzing it will be easier to identify. Best of luck
