A squealing noise generally indicates that there is something loading down the switching power supply. Generally a shorted component will do that. Without any other information it's hard to tell which circuit could be the culprit. It may even be a faulty power supply itself. Was there any problem prior to this condition? Any odd picture problems, shrinking etc. or sound issues, tuning issues?

RCA Model f27650 High pitch squeal


the high pitch squeal indicates shorted component/s. the transformer goes hot co'z its being overloaded by the shorted component, it too could be the one creating the squeal!!

if you have experience with electronic troubleshooting, try to test some of the components particularly on the secondary part of the transformer.
Be careful and make sure the TV set is unplugged.
test for shorted diodes and transistors, if you're in doubt of your readings try to desoldering one leg of the diode then proceed with the testing/measuring. replace any of the bad components you find exactly with same part number or replacements with the same rating.

spend more time on it resoldering some other cold soldered components.

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.
