It is a bad power supply for the backlight. That is the only section capable of such a noise. Good luck i hope this helps. I know i have heard similar sound from a laptop with similar issues! Prodzilla
Hi, TV needs lamp replacement as existing lamp got weak or has been reached to end of its working life, please note that lamp is not dead or broken so that is why lamp lit is not lit at tv front. Hope these info will help you. Thanks.

I have the exact TV and had the exact same problems. It is the light engine with color wheel that needs to be replaced, and they are VERY hard to come by for this model. Our repairman has had our TV for 5 months and still cannot locate a vendor that carries the part. He said according to Toshiba, the part has been discontinued. If you happen to find one, please post. I'll do the same.
My TV had the same problem. I called Sony yesterday and they told me to reset the TV. I did so yesterday, and it seemed to work. Here is the transcript with instructions: Please turn ON the TV.
While holding down the RESET button on the Remote control, press the POWER button on the TV.
The TV will turn itself OFF, then back ON again.
Release the RESET button.The TV will go thru the initial setup, and should work normal.
most times then not it's the capacitors on your power board that blew there for not supplying the tv with enough power if you open it up and check the capacitors it should be leaking some kind of liquid or the tops have bubbled up. its an easy fix cost>>2 dollars each
