Problem for RCA F36649 36" TV

36" model # F32672SB RCA

No picture or sound...only a very high pitch, (almost like the sound a silent dog whistle makes) when TV is plugged in. Is it worth seeking repair for this. TV is 7 years old.
I have removed the back cover. The part where the high pitch is coming from, looks like some kind of transformer.

Yea your problem is most likly the horizontal output transistor and transformer. They always go bad as a pair and ifd the set looked ok before it went out Its worth the repair as it shouldnt cost more then 150 tp 2oo bucks maybe a little more but not much more. Make sure they replace both the transistor as well as the transformer and also take out l401 coil and scrap off the extra enamle off the wire and reinstall and resolder. Good Luck

Likely the horizontal output transistor is shorted, & likely the flyback is also bad. Daniboy.

.... also have them check the capacitors in the horizontal driver circuit, as they can cause the output transistor to go bad (and take the transformer with it).
