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.

Sounds like a problem I had with a Polaroid t.v. Take the cover off the back and look for capactors that are buldging on the top. The top should be slightly concave. If they are convex at all, you can buy new one at Radio Shack and replace them for under $5.00

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.
