Question about RCA 36V430T 36" TV
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.
