TV not turning on; making high-pitched sounds - Tom's ...

Have you tried plugging it in without the surge protector? I would wager that either a) the surge protector needs to be reset/turned on and off depending on the model or b) either your TV and/or surge protector have been damaged by the power surge.

Try plugging the TV straight into the outlet and see if that helps.

The sound is made by the power source that is overstressed by a failing part - it's about to die. This usually happens because the capacitors on the power source have aged and they starting to behave as a short.
Open the tv and replace them all.

Most likely failed capacitors in the power supply. I am currently having the same problem with my 26 month old LN46A750. Samsung has agreed to fix this as an out of warranty "courtesy repair".

If it's new and has a warranty, take it back to the dealer and exchange it for a new one. There are no repairable items internally.

Hello, This is a problem with the switching transformer or the ballast used to fire the backlight. You will have to replace the ballast and or the switching transformer soon. In order to replace these items, I would suggest taking it to a qualified TV technician for servicing. I hope this helps, Thank you, Shuttle83 http://www.electron-age-technologies-llc.com

it's the power supply, there is a coil that needs replaced, or just replace the power supply

I have been having that same buzzing sound. It happens when you turn on the energy saver feature on the tv setup. Just turn it off. Smooth

I was told that these clicking noises (which happen on my Magnavox LCD too) were due to the "power required" at the internal switch. Seems that the power required to immediately turn on the TV is too much for a standalone household outlet, so it "surges" power in a series to get enough there. Hence, the clicking sounds are actually mini power surges to send more power to the internal circuits to turn the TV on.

If your set is like mine, these noises generally stop after a minute or two, correct?

PEOPLE, YOU NEED TO GO BACK TO THE STORE, BUY THE SAME TV AGAIN, SWAP THE TV'S AT HOME AND RETURN THE "OLD" TV IN THE "NEW" BOX WITH THE NEW RECEIPT. IN THE CASE OF TOO MANY RETURNS, HAVE A FRIEND, MOM, DAD, SISTER, GIRLFRIEND TO BUY ONE FOR YOU AND DO THE SWAP LATER.
NOTE: I REALLY HATE DOING THIS TO THE STORES, BUT IF YOU PAY FOR SOMETHING IT SHOULD LAST LONGER THAN 30-40 DAYS. PROBLEM SOLVED! :)
