Screen suddenly turned off, makes an odd high pitched noise when it tries to turn back on. power button flashes orange


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.

Won't power on


my d52w19 chassis itc222 as posted most of the time wont turn on and the green light flashes three times every time it makes a small noise. sometimes it does turn on and you hear a little pop and the tv fires up.  latley there is a really high pitch noise that will slightly change pitch if you move the tv or put slight pressure on the top or botttom rear part of the chassis. thanks for the help as I have seen that this has been posted before without mention of the high pitch noise.

The set is shutting down to prevent further damage. There is a problem with the high voltage circuit. The most common failure part is the horizontal output transistor. Figure on $20 or so for parts plus the local labor rate to get the total repair cost.

A high pitched tone is constant when the TV is on


The problem could be that of coil that has become loose and is vibrarating cause your squeal . Or it may be a transformer in the power supply that is also vibrating . These can only be replaced to get rid of your problem and you have to isolate which one is causing the noise . Good luck

High pitched squeal


What an RCA I hope you didn't pay mutch for this, NO it's not the part of the board were the cable goes in, the so call squeal is the horizontal oscilation of the coil you hear, narmaly it is at the rate of 15747 hz, to find your problem you most open the back cover, and while the ptv is on try to hear by insolating the noise were it is comming from with a credit car or something that will hide the section you trying to find, it will be a transformer or a coil, close to the power supply or the horizontal defflection section. To fix your problem well that's all a different game, you must contact me via e mail at rlandry@vianet.ca

I hope this help.
Meanwhile keep on smilling, life to short
