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?

When my rca 36F530 tv is plugged in it makes a high pitched buzzing noise picture does not come on


There is a short circuit in the high voltage circuit. the transformer who helps to create the high voltage or his power transistor is damage. replacement needed. the repair is not expensive, because the parts are average repair. Ask for an estimate.

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.

My rca tru flat is NFG


The high-pitched squeal usually indicates that the horizontal drive circuit has failed as a result of a dead line-output transistor. This symptom indicates that the control circuit of the main power supply is trying to over-compensate for a greater than usual secondary current. Certainly, an inspection of the line-output transistor will show that it's most likely dead. Sometimes instead of the squeal you will hear hiccups instead. Focus your attention on the horizontal circuit.

Who said it cannot be fixed? You can try and hook an external speaker to wires and test for sound. Maybe audio outs have sound?

Dead tv


That is typical with these units, The Horizontal output transistor and flyback go out in the RCA's 9 10ths of the time and causes this situation.
