High Pitched Ticking Noise

I have a F36705 RCA tv that makes a high pitched ticking noise in the back.  The TV won't turn on at all.  The ticking noise decreases in frequency once unplugged, then goes away completely.

My sansui tv makes a loud high pitch noise. I have had it 3 years, it is a a riging noise, and hard to hear the tv shows. what do i do?

ever since for ever, ive always heard a loudish high pitched ring from analog tv's. e.g. i would know a tv was on in another room even if it was muted. ive told other people about it but they dont seem to hear what i hear. so im gonna geuss either

a. analog tv's all make that noise to a verying degree but most people just dont notice it or subconciously cancle it out as normal.

b. its a kind of hyper sensitivity to high pitched noise, in essence, tinitus.

on a final note, its not medical as i always pass my hearing tests. but to answer your question, either buy a digital tv or turn up the volume.

RCA 32'' TV making a humming noise

sounds like a shorted horizontal output transistor probably caused by the high voltage transformer or hot. it is most likely fixable but it will be costly.

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.

A shorted horizontal output transistor or shorted flyback. If the flyback is shorted replace also its HOT.

Trouble turning on tv. High pitched noise/click.

The mainboard might have some loose components, or cold solder , or may be the filter capacitors are becoming faulty. Yes it is worth repairing, bring it to the repair shop. Cheers.

TV won't stay turned on, no picture, started making high pitched noise

That high pitched noise you're hearing is the power supply telling you that it has too much of a load on it and lowered its operating frequency which in effect cuts its output way down! Normally you don't hear any thing since the power supply operates at a frequency that's beyond human hearing. In an RCA this indicates more than likely that your horizontal output transistor is shorted and this short was caused by the flyback transformer shorting. This is a common happening with RCA's You'd need to take to a tv shop and have it checked out. Stargazer
