Buzzing when call on hold

Sounds like your power supply is causing the problem. Unplug the TV wait 10 minutes, look in the back for a red button (circuit breaker) push it in. If this does not work you have a low voltage power supply fault.

TV not turning on; making high-pitched sounds - Tom's ...

To lower the action on an acoustic guitar:

Usually just the saddle needs reducing.

1. Remove strings (or you may be able to just loosen them). Remove saddle, sand down the bottom a little at a time. Restring and check action.

The action can be set as low as poss without any fret buzzing or note choking on all strings and on all frets.

2. Repeat 1

If the action remains too high then there are other techniques.

Same issue here. Can hear the high pitch buzz, and friends complain about it.

I have 2 Turtle Beach X11 headsets, and 3 Xboxes (std, Elite, slim)

Unplug the mic, and no high pitch buzz. Plug it back in, and its back.

Tried all 3 boxes experience same issues

Playing with volume and mic settings doesn't make a difference.

Would love to have a fix for this :-)

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.

Sounds like trouble in the standby/power up circuit. have you tried unplugging the TV for a half hour and seeing what happens? It might start up but I think this problem won't go away. If you heard a high pitched buzzing it sounds like a problem in the high voltage not letting the start up circuit work. threy are related. The start up circuit waits for the high voltage to stablize and then switches it on.

I have a very high pitched sound and when I move the tv it will stop for a second or two and then start again. The sound sometimes stops all together. But very high pitch sound.
