I left my F32444 (32" RCA Entertainment Series) TV on all day by
accident. When I came how it was making a high pitched squealing noise
that sort of ocilates. Is there anything I can do to fix it? Or is it
beyond repair?

Thanks in advance!

You would have to have the set opened up, and determine where the noise
is coming from in the first place. Sometimes transformers or reactive
components can become noise, due to a number of causes. Some are from
failing associated components, or the reactive device is failing, or
its internal windings (for example) are loosening up, or it in itself
may be failing.

Your best and safest, and best solution is to call an authorized
service tech, and have the set properly checked out.

In the way of repairs, the end user is very limited in what they can
do, unless properly trained, properly equiped, and have the proper
facilities to do TV servicing.

When working in TV sets, there are very serious safety issues to be
considered.

Actually if its a ATC XXX or whatever maybe the HOT is S/C
and the pin circuit also has trouble.
What's the Chassis number CTC XXX?

Well, maybe... or maybe not. The OP did not say if he still had picture
and sound.... AND the "high pitched squealing noise" TOO..... if so, the
flylback and HOT are obviously OK, as you obviously would already know.

Kip and others,

RCA had bulletin out on switching power supply noise but that was long
ago so most of chassis had the fix.

But one remain is RCA being cheap didn't secure ferrite beads on
component leads. Secure them with silicone glue by dabbing them to
the PCB and some to end of it to the leads. This will stop the squeal.
There are four beads on two diodes on output side of power supply,
usually one or two on a diode in horizontal circuit.

I had to do this frequently for this complaint and all CTC203 and
ATC113 get same treatment for any reason.

Cheers, Wizard

dont forget the divining by entrails!!!

Transport unit to safe area away from children and small pets.
Douse with lighter fluid.
Stand back a safe distance and propel lit match at said unit.
Problem solved.
