Question about RCA F35673MB 35" TV

1 Answer

High Pitched Sound

I woke up last night with my TV making a high pitched noise.  The only way I could get rid of it was to unplug the T.V.  The television does not work anymore.  The TV model number is RCA F35673MB.  I know that RCA's are not reliable televisions but I just want to know what I need to do to fix this problem and if it will be a quick, easy, and cost efficient fix.  I am an electrician so I am not afraid to replace any resistors...transistors...etc. 
Thank you.

31gt660 TV will not turn on. Makes high pitched sound.

This set has a shorted horizontal output transistor and possibly a bad high voltage transformer. If you repair the set, also solder the horizontal drive for the transistor listed above. Try for parts. the h-ouput transistor is p/n: 223942 and the transformer is 223952 .Thanks and good luck.

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.

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.

High Pitched Noise

most high pitch noise comes from the anode conection on the picture tube thats connected to the flyback anode cap thats mean there is a high voltage leak,to stop the noise you can discharge the high voltage take off the cap and clean with alcohol.if the noise will have to put some red or clear silicone both the cap and tube stick together leave to dry for about 2 to 4 hrs.this will eliminate the leaking.good luck.

High-pitched noise

Most of the time it is just a coil or the high voltage transformer itself that is vibrating causing the noise. The high voltage trasformer has an iron core that goes through the center of it and there is usually a giant clip to hol it together. That clip ometimes is loose causing the vibration. Usually you can listen for the sound when the back is off (careful there is 30,000 volts present while in operation and the tube holds a charge even when off) and press on different coils near the transfomer with a long plastic tool (no metal to avoid shorting components out). When you find the one that is the most sensitive with the slightest touch you can usually apply hot glue or silicone over it (with TV off and unplugged) and let it sit for a while. Good luck and be safe.

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
