Check its back-light inverter board. Replace it.

is it hooked up to an extension cord or a cable box?

You are dealing with a failing backlight inverter. You are hearing the surface mount components failing over time and that buzz is them not keeping up with the voltage coming into them. (Hz) You will need to open the tv and locate the noise and replace the backlight inverter :)


Please rate if this helped :D

Yes, I would exchange it for another ASAP.

Bearings in color wheel going bad and needs to be replaced. Call a local tv repair shop on pricing and availability of color wheel for your model and chassis

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.

Hope it Helped U!
