It takes a fair amount of power to make an audible noise like this. Only the power supplies are suspect. Either the low voltage supply that runs the TV's "smarts" or the high-voltage supply that powers the screen. Either way, it is bad news - You do have this under warranty don't you?
I don't care which of the new TV technologies you buy, they are all doomed to expensive repairs. Always keep them under warranty.

If an authorized service repair center will sell you one. However looking at the reviews you may just want to replace the tv since even service centers have issues repairing the tv.

Ihave a 42" ilo plasm tv model number PDP4210EA1 i've had it for three years picture went black and only sound is comming out, anything i can do to get picture back at a reasonable price


I've had a same problem with a similar TV. The odds are the power supply board for the screen has failed. Most manufactures call it a Backlight Inverter board. If you have some electronic experience, you can some times find a Service Manual for your TV on the internet for less than $20. It will have all the research material for repairing the damaged circuit board.
