There is a stand up coil about 1" tall and the dia of a nickel close to the HV transformer, the iron core glue comes loose over usage. This can be cured by replacing it or using a sealer/caulk and re-seal the coil. Hope this helps, it is not an expensive job for service.

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.

Makes a squealing sound but there is no picture on the screen


Hi
The squealing sound that you hear most likely comes from the power supply.
And it is most often caused by a shorted horizontal output transistor.
But that would have to be determined by opening the set and testing it. It is a common problem in rca`s and other sets, it is often caused by a bad flyback(high voltage transformer) and/or associated circuitry.
Hope this help to clarify things a bit.
P.S please do not rate this answer(unless it helps)as it is only a suggestion/information.

Loud squealing noise first 5 minutes after tv is turned on


Sounds like the color wheel. It's the only moving part in most DLP's and the bearings can go bad. If it manages to get up to speed the picture may look normal. One temporary solution may be to let it run a few minutes, then turn the set off for 10 minutes, then turn back on. When my color wheel was going bad that would often quieten it down. For the rest of the day, try to leave the set on, especially if you're only going to be away from the TV for short periods. You can turn off your cable or satellite box but leave the set on and you won't have to go through the hassle of trying to quieten down the color wheel until the next cold start. Of course the best solution is to replace the color wheel which even with a rebuilt unit won't be cheap if your warranty is expired.

Stopped working and squealing sound


Your set is shorted circuit condition. The power supply is making the noise. Unfortunately almost any of the hi current circuits will do this. If picture went out 1st look for video or hi voltage problems.
