Ive had a similar model since 2002 and it had the same problem. Factory power supply to weak for the model. Mine was replaced twice before the upgrade came out. Sorry, I dont think it is a $.50 solution.

could be power supply problem or high voltage problem. check caps in main power supply first.look for caps that have tops puffed up ususlly three or four.....

SOURCE: My rca tv d52w17 won't turn on.
Sounds like a faulty power inverter to me.
If it's covered under warranty, take it back to where you got it and ask them to cover the warranty for you.
If it's not under warranty, take it to a local electronics repair store that deals with TVs. Get a quote from them on the amount to repair it.
If it exceeds a third the amount you paid for the TV in the first place (ie if the TV cost you $1,200 and the bill exceeds $400) you're better off to get a new TV.

SOURCE: Clicking sound!
The TV is on protect mode. The clicking sound is the protection switch
that keep turning the TV off to prevent further damage, this happens
when a fault had been detected.
Try first leaving the TV power cord unplugged for some times, let say one hour or so.
Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.
If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.
The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.
1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.
2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.
If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.
If you are in situation 2 , then there is an internal fault.
Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.
Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.
If under warranty contact the manufacturer ringing the number on the user manual
If you want to repair at your own expenses, just locate any good qualified repairer.
