It may be coming from the power supply module or from the backlights inverter board, you need to look close to hear where it is coming from first, it may be a bad sign of worst damage to come so I will not leave it plug in since the power supply is running 24/7 even the TV is in the OFF mode.
If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:

When I talk, my friends complain of a high pitched buzzing. I'm using the Turtle Beach X11 via a wired controller on the Xbox 360.


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 :-)

If the whine changes pitch with engine RPM it could be a serious problem with the alternator. Possibly the voltage regulator, or a shorted diode in the alternator causing high frequency AC to be fed into the harness.

RCA D52W19B makes high pitched buzz when on


Sounds like a coil is vibrating or a component is bad causing the transformer to whine. Could possibly just need soldering.

High pitched noise


I am about to post a in depth guide about how to fix this problem. It's because a capacitor inside the TV has blown which causes the buzzing high pitched noise. It's really easy to fix however and only costs about £1 / $2 to sort out.

You can read a similar guide here http://www.fixya.com/support/r741402-polaroid_flm_373b_lcd_tv_black_screen but I will shortly be uploading a guide on the buzzing problem!

High pitch buzzing and no picture


Your power supply, I mean the internal power suppy could be faulty, if you know how to deal with it, check it for abnormal oscillation, or get some help from someone who knows how to repair it.
