Question about RCA F32450 32" TV

1 Answer

RCA Model F32450

Our TV was working fine then shut off. We turned it back on and we do not receive a picture, only a high pitch sound when we plug it in. We cannot turn the sound down with the remote. We have to unplug the TV if we don't want to hear it. We're not sure if it would be worth it to get the TV repaired or just buy a new one. Any ideas?

Toshiba HD ready TV ct 90158 makes high pitched sound


A high pitch sound can be a capacitor losing power it would sound a bit like a fire work. most have back up on the board but it put more pressure on them the more times you use the tv. would check them and replace. all of them can be 5 in a row in some models.

I have a RCA 32 TV made in 2002 It shuts off and turn and nothing


If its a F32450 it is prone to two parts failing.

I presume you mean you turn it on and it shuts right off.

A question? I you unplug it and plug it back in do you hear a high pitched whine for a moment or longer/

This model (along with some others) has a problem where the High voltage Transformer fails.

It will usually take a transistor with it. I have fixed dozens of them and usually just need to replace two parts:


Transformer is location LL05 and part number is 257805.

Transistor is location TL02 and part number is 237470---generic number is 2SC5148.


The giveaway is if someone checks the transistor and it is shorted--the transformer got it.

I can tell you a place on EBAY that will have both parts for less than 30 dollars total.

Clearly, I do not know if you can do this repair--I do this for a living and replacing both parts in this set takes less than 20 minutes.

Let me know if you have questions and I will try to help you---

If this helped you at all rate this solution as I do this here for free.

Will not turn on


Does the set make any sounds. DOes the front green led light or flash when you try to turn it on.. if not then it could be as simple as a fuse, if it does flash then it can be many problems
