Hai,
Buzzing can be caused by a bad ballast, colorwheel, or cooling fan... Nothing else makes a noise, unless it's comming from you speaker.

Buzzing/humming noise that increases as you raise volume. So loud that you can not even watch tv


Hello snow1525,

You may have a torn speaker element. This is usually the cause of buzzing noise in the sound, also you may have a bad capacitor in your audio section. This is what I would suggest doing as a test open the front bottom panel of your TV and visually inspect the speakers for signs of ripping and or tearing in the speaker element. If the element or elements are torn it may be possible to repair it with rubber cement or rubber paste just coat the tear with the rubber cement to hole the torn edges together and allow it to dry for two days before testing the sound. If the speaker elements are not ripped then the problem may be a bad capacitor either in the audio section (power supply) or in the filter block (usually attached to the speakers to separate bass and treble signal to the speakers.

I hope this helps,

Thank you,

Phillips 32" LCD TV, Sound through TV speakers has a buzzing noise which is steadily getting more aNNOYING AND LOUDER.


We are having the "buzz" problem with our new 42' Phillips LCD too.

We do not have a sound system yet...but have read they have the same problem, so I won't assume when I get a sound system it will go away. What I did do for now...and it helped..

Go to the SOUND portion of TV menu
Choose EQUALIZER
Turn down the two FAR RIGHT columns, they are the treble. It helped us.

I have been having that same buzzing sound. It happens when you turn on the energy saver feature on the tv setup. Just turn it off. Smooth

Set has a defective color wheel. This needs to be replaced and your tv will go back to normal.

Sony Bravia LCD T.V.


It is most likely a fan (there are 2 to 3 of them in the set) that is making the noise. I doubt seriously that the lamp is causing a buzzing noise. The only other buzzing sound can come from the ballast wich powers the lamp.
