The TV is on protect mode.
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.

Check the capacitors on the power supply first. If any have domed tops or signs of leakage, replace them. I had two go bad on mine. Call electronics parts supply stores first as these are not your average capacitors.

SOURCE: samsung hd tv will not turn on
Just wanted to confirm the solution (or atleast solution to MY problem).
Thank You to those who posted the solution to this problem.
I have a Samsung 52" HD LCD TV. I bought it 1 1/2 yrs ago and recently had been experiencing this problem of continual clicking and no video upon power up.
It would take approximately 3 - 5 minutes before eventually turning on. I noticed that prior to turning on, the clicking would get faster and the blue light at the base of stand would begin to get brighter.
So, based on the suggestions here, I opened up the back of the TV and located the Power Supply. I visually inspected the capacitors and in fact, found 2 of them that had a subtle but obvious bubble or protrusion on the top -vs- flat tops, like the majority of the caps.
These caps were 2200microfared, 10V rating. I went to my local Radio Shack and bought a higher rated version of the 2200 microfared caps (35V). I Replaced the old caps with these new ones and it solved my problem. :)
There were a couple of caveats though:
1) the higher rated caps were physically larger & had axial leads vs radial leads.
2) The leads of the larger caps were just thick enough to prevent them from being inserted in the board.
3) Rather then make the holes of the board bigger and risk destroying the solder pad, I used appropriate sized leads from some resistors that I had as extensions and soldered the new capactiors to the extensions. Of course you need to be aware of polarity and assure that the leads will not come in contact with each other or anything else on the board.
4) Capacitor Radio Shack p/n: 272-1020. Total cost of both was less then $10.
Hope this is helpful. I did take some pics of the capacitor location and board location. If anyone would be interested in the pics, you can email me @" firstname.lastname@example.org"

For best performance I recommend you connect a HDMI cable from the PS3 to the HDMI input on your TV.
To display the PS3 you need to select the HDMI input on your TV.
