    Hi, I do not have any electrical expertise or anything. I dont have any schematics. I don't know if it is any different, but my tv is an Rca 52in.w15. When I hit the power button the green light will come on with a high pitch sound and the green light will come in and go out about three times with no picture or sound. What should I do from this point?

Hi

Thanks for using FixYa. High pitch sound is caused due to power supply. You'll need to open the back of the unit and check/test HOT (horizontal output transformer) and flyback, replace the part that has gone bad however, replacing both the parts at the same time is recommended. Also check the power supply board for any bad components. This is only recommended if you have electrical expertise.

My tv makes 3 even high pitched squeals when i turn it on. about 1 second each, then powers off. No picture no sound. All imputs. What do you have for suggestions on what it could be.


One of most two common reason why your set will not come on, is because it has lost the high voltage, the first thing to check is your horizontal output transistor, to see if it is shorted, it will be located bay the flyback, mounted on a metal heat sink. That is what is causing a squealing noise.

TV making high pitch sound


Hi, There are usually 1 or 2 fans inside the TV's. Could be worn bearings, or fan blade interference. Sorry, without my electric ear working, I can only guess.
