Re: tv problem

Des the set come on at all? If not, there is a short inside this set. most likely, a shorted horizontal output transistor and a bad flyback transformer. good Luck

Unplug the set, press power and hold for 60 seconds, let it sit for 30 minutes and plug the TV back in, try to power on, if no change! the problem is power supply or high voltage issue.

Turned on tv & it made a crackling noise, so i turned it off & cleaned insice with an air duster. Left it off for a while then turned it back on, it made a low beeping noise.

Not knowing the brand or model number, I would start with the horizontal output transistor and high voltage transformer (both are in the same circuit). When the horizontal output shorts, it puts excesive load on the power supply causing it to chirp or "beep".

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.

RCA 32 in TV no picture no sound just a beeping noise TV power is on

the tv has one part of the power supply working this is needed to have the microcontroller ready to work. But the tv needs more than that for work im talking 'bout the high voltage power supply who is now damaged. the parts required depends on the diagnosis in the bench but at least two are needed. the cost of this repair of course depends in how many parts are going to be replaced, but i concider this repair kind of average in this technology.

My TV shut off and will not come on

This is an issue with one of your power supplys wether it be high voltage horizontal power supply or the reg power supply. The beeping noise is letting you know that it has some power but not enough to start the high voltage needed to create the picture on your tube. I would seek professional help for this issue.
