LG TV makes High Pitched Noise and will not turn on

Hi, I experienced a freak lightning storm while gone at work and now my 42" LG LCD TV will not turn on. When I plug it in, it makes a high pitched noise and the power button stays lit (red). When I press the power button to turn it on, the TV does not respond. Can anyone tell me if my TV is repairable? Or is it a total loss?

SOURCE: High Pitch Noise on 42" PLasma Gateway TV

how old is your plasma TV? try check the switch / volume of the sound settings.. Sometimes, when you always increase the volume, it will tend to alter the limit of sound and causing the sound to provide sound undesiredness. I suggest to check it with a liscensed technician.

SOURCE: high pitched noise from inside the TV when picture comes on

Hello randapaint,

This might be from the IHVT (Integrated High Voltage Transformer), or more specifically a short in the IHVT causing it to arc, producing the high pitched whine, you are hearing. Take the back off of the TV and try to detect where the sound is coming from, more then likely you will notice it coming from the section that contains a large component with a large red cable coming from it, to the top of the CRT (picture tube). Replace the IHVT (with the exact same model) if it is bad.

I hope this helps,

Thank you,

Shuttle83

I would recommend getting a surge protector and using that to protect your televisions. This usually will stop something the lightning from killing your tv's.. I have a surge protector and can still use my tv, computer, anything I have plugged in during a storm.

It might have been blown out by the lightening storm. that happened to two of my tvs that were plugged in during a lightening storm. they both, and two dvd players, would not work after, but the ones that were not plugged in were fine. You should unplug your major electronic equipment during a storm, unless you have a power surge plug/equipment.
