Question about RCA F36705 36" TV

2 Answers

High Pitched noise returns after new parts installed.

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.
Comment by Toadw, posted on Oct 25, 2007 The service number is F36705YX1. Will I have to do any soldering to replace?

Horizontal output transistor is shorted,caused by bad flyback
transformer.If you want to pursue the repair,please give the
service number off back......I will get part # s........T.
Comment by Terryfic, posted on Oct 25, 2007 Both parts soldered in Part #'s 241319 or ASTI 2170 xformer
and 237470 transistor ........T.

I replaced xformer and transistor. The TV worked good for a week but now it is doing the chirping high pitched noise again and won't turn on. I bought the parts from MCM Electronics. Could parts have failed already or did I install something wrong?

Check the connections at T14101 pin 9 get loose after time and could cause Q14101 to fail again

Same problem, high pitched noise over regular sound and no pictur

No guarantees with this diagnosis. But it sounds like an HT ( high tension) leak This is often caused by the lead becoming partly unplugged ( being bumped or moved) and because of dust buildup it arcs making a high pitched hissing whistle.Ther lamp may also have been affected by the HT leak. The safest option for you is to call a service technician to it, as opening it up could cosntitute a a danger to the unskilled.

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.

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
