It sounds as if the lamp needs to be replaced. The buzzing sound you hear is the ballast attemting to fire the lamp.

Was working fine last night ,went to turn it on and you can hear a buzzing by where you plug in your jacks a bee,or high pitch sound.tv has no picture or sound.only sound you hear is this buzzing

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.

Hello
The LOT [Line Output Transformer] of your TV has damaged. It is the one, that supply all the voltaged needed to CRT. Its internal windings will get shorted in between, and is irreparable. Replacement is the only remedy to this proble. Replace the horizontal output transistor also with this. you haven't specified whether there is picture with your tV or not. If this high frequency sound is along with picture, there is some loose in the cores of the SMPS transformer, or LOT itsef. If there is no picture at all, and this high frequency sound is there, no doubt; LOT is damaged. OK.

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 :-)

Loud buzzing noise on vizio tv

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.

When my rca 36F530 tv is plugged in it makes a high pitched buzzing noise picture does not come on

There is a short circuit in the high voltage circuit. the transformer who helps to create the high voltage or his power transistor is damage. replacement needed. the repair is not expensive, because the parts are average repair. Ask for an estimate.

Rca 27410tyx1 will not shut off

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.

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.
