Buzzing at low volumes in front channels

sounds like a transformer having an issue either the power supply or inverter. You should be able to isolate which one by removing the rear cover then turning on the cover. ( Dont touch anything when its plugged in and playing just listen to see if you can tell where the sound is coming from.)

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.

have someone check speaker ground to the TV chassis. Your speakers are picking up reverb from the Video Signal.

change your pre-amp ic sure it will work. or maybe cold solder from the board.

Well, some TV stations do broadcast at different volume levels. This is very noticeable when watching a TV show and the volume seems normal and then when a commercial comes on, the volume is very loud. They do this to get you to pay attention to the commercial. Another problem might be that you are adjusting volume from both your TV and your cable box. What you should do is make sure your cable box is set to "FIXED VOLUME" and then just adjust your TV volume. Fixed volume will have the cable box output only one volume level, letting the TV do the adjustment. Just go through your cable box setting and look in the audio settings. Hope This helps...

Test it by moving the bass and treble up and down. If the buzzing seems disappear at lower volumes with little bass and appears from one side only, it is probably a blown speaker on that side.

If the buzzing is apparent even at very low volumes or from both sides, it is probably an audio board issue. I am not certain if your model has a separate audio board or that functionality resides on the main board.

Is this buzz from the speakers?
Is this buzz from the set itself when the sound is turned down?
Is this buzz a low pitch sound?
Is this buzz a high pich sound?
Does this buzz vary in loudness with the volume control?
Does this buzz change in level from time to time?

You should post the details and the circumstances of use in order to give some idea of the conditions.

First- Do you have a cable box ( with a volume menu in it)?
If you do make sure the volume on the box is at least 3/4 full, no lower. Then re adjust the volume on the tv to a normal level and let me know

Channel level output can be adjusted in the menu if you have the remote. Set the rear channel level volume higher and the fronts lower if need be, and then turn up the volume. Enjoy!

I would think that your mic part is shot or you need to adjust the volume of your mic. Go to Start---->Control Panel---->Sounds And Devices---->Volume----->Advanced now adjust your input mic levels a little lower.
