Question about RCA F32TF720 32" TV

1 Answer

Yet another hissing/buzzing noise from back of TV

As soon as the power cable is plugged in the noise begins.
With the back off it is clear that the noise is coming from the main board at the bottom and not from the board that attaches to the tube.
Absolutely nothing works, will not turn on, power button does nothing, no lights on anywhere.
Remote is missing, is there some sort of reset on the unit itself?

Any help is appreciated

Re: Yet another hissing/buzzing noise from back of TV

Good day.

Check for the horizontal output transistor, flyback and filter capacitors.
Any of these being shorted can cause the problem.

Toshiba 36zp18q buzzing noise.

Humming sounds come from the power supply and buzzing sounds come from other circuitry. Most likely a capacitor somewhere.

High pitch buzzing.

Hi there
Let's make ur problem a bit clear. "white lines" how? where?
meaning retrace lines with full raster or a single vertical line?
buzzing sound? without even turning the power switch of the TV to "ON" or when u just plug the power cord?
I'll check for schema, mean while can u tell me where the resistor leads to? is it a fusible resistor? if so , to which area the resistor suppliers power?

Do you have a baby monitor or cordless phone or even a cell phone plugged into the same or close outlet...any such thing can cause interference.

Buzzing sound

You haven't specified where the buzzing sound is coming from, if it is coming from speakers, changing capacitors in the audio section will fix the problem, especially the filters. Now if it sounds like a hissing sound from back of the tv, the CRT base socket is the culprit. It is an easy thing to fix, and the base is cheap, but make sure you purchase the exact same type of base or it will harm the CRT. Good luck.

No sound or Picture, Just a hissing sound.

well what sounds like happened is you blew up the tube in it. have you unplugged it from the wall and just let it sit some times that helps because what will happen is there will be a Electrical build up and it won't work right. an other thing you might want to do is hit the Degauss button on the remote. plug some sort of video signal into it and go through the inputs to see if that helps, mine did that every thing would just be black but i plug in my video camera it would detect it and make sure that the audio cables are plugged in these TV might just be that old that they have to have both audio and video in order to work.
