Question about RCA F20645 TV

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

Visio VP504 fhdtv10a - When I plug it in, it has an amber logo light and makes a click noise (like a relay). When I press the power button nothing happens.

These are problems gradually developed in TV over the years. You may have to look for any dry solder, change the capacitors that look 'puffy' and try.

52" rear projection tv has no power and fuse is ok

The clicking noise that you are hearing is actually the power relay. Normal operation by either the remote or the power button on the front panel, you would normally hear a soft click just after the press of the power buttons to turn the unit on or off. When you initially plug the unit in to power, you will hear the same click noise. Being that you are hearing it all the time indicates a failed relay. TV's now a days, or at least ones built during the last 15 - 20 years have different Printed Circuit Boards (PCB). There are PCB's for power (which youre dealing with now), sound,video and so on. The PCB that you need to repair your clicking issue will run you about 80 U.S. dollars for the part plus the average going rate for repair from a qualified service tech. You could purchase the part from Thompson Consumer Products repair and fix it yourself, but be aware, there will be no warranty on the part itself unless an authorized tech does the work. Located on this PCB is the power on/off relay, fuse, usually 4-5 connectors for power to different PCB's (depending on model and features). Now depending on how old the TV actually is, you may want to invest in a newr set, the reason why I say that is, is because the new power unit may and can overload the other boards and cause damage to them and now you have a new problem to deal with( along with more money being tossed down a hole.

Good luck

Power button makes a click, click sound

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