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

A high pitch sound can be a capacitor losing power it would sound a bit like a fire work. most have back up on the board but it put more pressure on them the more times you use the tv. would check them and replace. all of them can be 5 in a row in some models.

Sounds like there is a power problem if the neutral (return) wire on the power supply has become high impedance (or even disconnected) then you will get a high pitched sound coming from the TV PSU also the voltage that is presented will not be 240V which will give you the same problem.

The orange power button means standby if you fix the PSU then the TV might work again but it may have been damaged by the PSU.

You can tell to some extent what it may be by listening carefully and trying to identify the location. If you, remove the back cover of the set; stay away from danger, just listen to where it seems like the sound is coming from. If it is coming from inside the high voltage cage it is the flyback. If coming from around the main power transformer it is one of the power supply parts.

The mainboard might have some loose components, or cold solder , or may be the filter capacitors are becoming faulty. Yes it is worth repairing, bring it to the repair shop. Cheers.

Sounds like the power supply is making that noise. At this point I would just exchnage the TV.

Sounds like the flyback and horz output is shorted.
