Re: Set wont turn on
I see that your TV's high voltage flyback is leaking out.
or the flyback cap to the CRT aka picturetube is dirty, or it has a open insulation.
(Warning: Flybacks are extremely dangerous, it has a high voltage that kills. becareful.)

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.
it sounds to me a transformer in your set has gone hard to say witch. im guessing it is a CRT set the best thing i could suggest would be to take it to your local tv repair shop they should be able to sort this for you and it shouldn't be to expensive.
try unplugging for the power source for 60 seconds hold in the power for 10 seconds then plug the power cord while you are hold int power button in then release the power button... now try it (turn it 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.
Most likely the TV is detecting an internal problem with it's circuitry and is shutting itself off to prevent further damage. You'll need to have a professional look at your set to determine exacly what's going on. Aside from leaving the power cord unplugged for five minutes, then pluggin back in and trying it again, there's nothing anyone can do from here. Sorry.
Hope this helps, and please rate my advice, good OR bad.
This denotes a problem with the switching power supply or the high voltage power supply. what is happening is the safety relay is being actuated by the shutdown circuit. Any number of things can cause this proble but more then likely the problem is in the high voltage power supply section and or its associative circuitry. The switching power supply and the high voltages power supply have very dangerous voltages and I would not suggest that you work on the TV set unless you do have a background in electronics. If you do not I would suggest that you take the TV set to an electronics shop for repairs. If you do have a background in electronics, you will need the following items:
1) A schematic diagram (to know where voltage and signal test points are located and to have a reference of the levels.
2) A multimeter (to measure the DC voltage levels on the TV Set)
3) An oscilloscope (to measuer the AC voltage and signal levels in the TV set and compair them to the values in the schematic)
4) A signal generator (to generate a reference signal for troubleshooting)
