Question about RCA F20645 TV

1 Answer

RCA F20539DG The TV was working fine but now there is a relay "clicking" noise when the power button is pressed. It will click several times and sometimes will actually turn on again and work fine (once it's on). Seems it will stay on and work as long as it's not turned off, then you have to put up with it never turning on again (click click click) or just let it keep clicking/cycling until it finally turns on again. Any ideas of what needs replacing before I just throw parts at it? I'm an electrician but not electronics guy. I am aware of the dangerous HV interior parts to fire the tube, etc. but am not uncomfortable working on it "unplugged".

YOU might have a bad relay or a bad solder connection in the relay control circuit. Sounds like a bad solder joint. Stargazer

Turn off itself and wont turn on. There is a noise, when you plug in. Click, click

Your description indicates that the power supply has failed; the noise you are hearing is probably caused by a relay that is interrupting the AC supply to avoid damaging the supply any further or causing a fire.
Disconnect your set from the wall and allow several hours (overnight is better) so that dangerous voltages have a chance to discharge.  You will have to gain access to the lower section of your system to look for a separate board with larger components on it, some cylindrical (capacitors), some block-like (chokes and transformers). If you can locate this board, it should be user replaceable.    

The next step would be to look for unique markings on that board looking like an assembly number. With that in hand and the model number of your set, look for the RCA service center in your area and call them to determine whether they have a repair or replacement assembly.
If only a replacement is available, keep the failed unit for possible repair in the future when the new one fails since mfrs. will not have entire assemblies available in a few years.

TV will not turn on

Hi, If the clicking noise is metallic, could be a relay switching on/off. What's curious is that once powered on by remote, apparently the clicking doesn't affect the TV, meaning it continuously work. The relay is suppose to turn on or off a function of the TV and apparently it is trying to but there is not such effect since the TV, as I understand from your post, works. The relay can be for the degaussing coil, power supply, over voltage protection. Since this involve a little diagnosis of the electronics, soldering and probably a minor component replacement, an on-site service/repair man would be your best bet. Even if it were a nuisance/minor repair, you can at least get the clicking noise out. Other than you get to get a checkup of the TV and diagnosis of what caused/started the clicking sound in the first place. Hope this be of help/idea. Post back how things are or should you need further information. Good luck and kind regards.

Power button makes a click, click sound

The sound is coming from a failed flyback auto transformer. You will need to replace that.

Tv wont turn on

The green light indicates that it is getting power from the outlet ok.
The clicking is the power relay trying to turn it on but there is an internal fault forcing it to shutdown. You either have a power supply problem, horizontal output transistor (HOT) is shorted or a bad flyback transformer. In any case it can most likely be repaired by a qualified technitian. If it is the flyback it may be expensive.

A32B43W Power Problem

The relay is part of the overcurrent circuit. This denotes a problem in the HV power supply. Try to resolder the relay just in case the it has a cold solder joint. If this does not help get a schematic and a multimeter and check to see if the voltages around the power supply seciton of in order. If you do not have a background in electronics please take the set to a TV repair shop.

TV Clicks on over and over

When you get this "click" it is the power supply trying to start. This indicates a short somewhere. Most of the time it is the horizontal output transistor and probably the flyback transformer that have shorted. Stargazer
