SOURCE: Power LED blinks red
it is a bad fan. it also could be a power supply. Quite often the real problem is dirt clogging up the fan(s) to the point that they need to be replaced. Operation of the set in a dirty environment is not a good idea

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.

There are three fans the one that usually fails is located on top of the optical block and cannot be reached by the owner unless you take the set apart yourself. What is happening is that one of the fans are not spinning fast enough or has stopped altogether. The best solution is to replace all three fans cleaning may not be enough to get a slow fan up to speed, and the tech should blow out the dust in the duct work. This is what the tech coming out will (or should) be doing. Also some fans will have an intermittent startup, and cause this intermittently, so it is a good idea just to replace the fans instead of just cleaning them.
