Sorry to say that it sounds like the high voltage went out on that one. The sound that you hear is probably the high voltage arcing across the flyback transformer. Dont try to make any repairs here. The unit has at least 25,000 volts in there. Even long after it has been unplugged. I'm not sure what size TV that is from the description, but you would be looking at replacing the main deflection board, which may well exceed the value of it.

What part needs to be replaced when your tv takes a surge and does not power up just sounds like a whistle


the whistle is the crowbar action in the power supply as it detects an error it slams that current into a coil an shuts.
try isolating the power supply pull all connectors
if nothing happens no whistle then either its external board or one of them gives it feed back to allow it to turn on . best can do.

LG HD Flat screen TV whistles


Ur power supply board is where the whistle came from.
Open the back cover,take a screw driver back handle taps all the transformers, so all the gaps pockets in the transformers clear up.The whistles will stop.

High pitched whistling


Try changing refresh frequency, color depth or resolution (wait for the whistle to appear before testing). Admittedly, you might have to give up some image quality - less colors, or less resolution. There is probably a problem in the TV syncing mechanism - if you can, try getting it replaced. "High pitched whistles" in video and TV hardware are usually harbingers of bad news.

I think maybe the G-board needs to be replaced. A TV shop will have to repair it. They normally start around $200.00

Continuous low whistling or thin buzzing noise


The high pitched sound is an indication that theres a short most likly in the Hi voltage sweep section or power supply and with out the proper training you should not even take off the back as there are no user replaceable parts inside of these sets. All the parts are soldered in and you can not look at them and see that they are bad.. its almost like when your check engine light comes on you look but what do you see without a computer to read the on board computer vto see what the problem(s) are. Take the set into or call a pro to assist you with this repair. good luck
