This particular model has a history of this problem.
This sounds like a safety feature built into the television. It may be trying to protect itself from an unsafe electrical source. The more expensive the equipment, the more sophisticated the power supply that converts the power from your outlet into your television. There could have been a lightning strike that has disabled the tv. Or it could be a faulty outlet.
Before called for a technician, I recommend plugging the television into a different outlet. use a good quality extension cord if necessary. You may find that your outlet is not polarized correctly.

SOURCE: Making sizzling noise
My Ionic Breeze GP had the hissing problem from time to time. When I first got it, I even sent it to have it replaced and the replacement unit also started hissing. Therefore I think it is a pretty common problem.
Cleaning it as described in the product's documentation and in other Fixya solutions such as this one:
seems to help a lot of the time. Also, more frequent cleaning (don't let it get too dirty or wait until the light comes on) seems to help. However, I've had time where no amount of cleaning, blowing air, claning the wires, etc. will make it quiet.
That brings me to my point:
I recently had to take the whole unit apart after it totally stopped functioning. This had nothing to do with cleaning, but was a bad switch (my posts regarding this fix are also on Fixya). What may be relevant is that when I had the unit apart, not only did everything get a good cleaning, but I also found several dead insects that were down in the bottom part, down by the power supply components, down where you would not normally clean because that area would be behind plastic covers.
After removing the insects and blowing that area out with a can of air and dusting with a cloth, after reassembling everything my Ionic Breeze is running the quietest it has since it was new, and when it does make noise, normal cleaning makes it go away.
What I am suggesting is that maybe some of these chronic noise problems that so many people experience are due to dead bugs or dirt beyond the area that one normally cleans.
BE CAREFUL IF YOU REMOVE THOSE COVERS. YOU DON"T WANT AN ELECTRIC SHOCK. MAKE SURE THE UNIT IS UNPLUGGED AND DON'T TOUCH ANYTHING WITH A CONDUCTOR MATERIAL OR YOUR HANDS.

First you should check the fuse and the wiring in your tv by removing the back cover. Make sure no wires are bare or touching. If there are any, wrap them with electrical tape.
If you cannot see anything wrong by looking, then it is probably the set has a bad transformer (high voltage)
