Question about RCA F36649 36" TV

2 Answers

Buzzing noise with no picture or sound.

My RCA 36" F36649 started making a buzzing noise and will not show a picture or produce any sound. When I unplug it the buzzing stops and them returns when I plug it back up. From reading some posts it sounds like maybe the power supply, so does anyone know how difficult it is to replace the power supply? Or could it most likely be something else? I've done some amatuer soldering and am willing to try repairing it myself, just not sure where to start. Would be greatful for any response.

    Thanks Stargazer for the response. So do you think an amateur could repair this problem? If so any advice? Do you recommend any particular place for parts? Thanks again.

The power supply is telling you that it has a short. I think you have a bad high voltage transformer in the horizontal deflection circuit. I've repaired several RCA's with this very same problem. The newer RCA's are vert prone to high voltage transformer failure ! Stargazer

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.

Buzzing noise


Fly back transformer will cause a buzzing sound like this. Really up to you how bad it bothers you it can be fixed but it will cost a couple hundred dollars. If you can solder you can put it in yourself but the flyyback will still cost a little bit of money.
