Refer to owners manual ! Blinking indicates the type of fault that is occuring on all your tv sets. example : power light on red - indicator light beside it green but blinks rapidly for half a second rapidly then shuts off. This refers to a faulty lamp or a lamp that is near its expiration. Read your manuals if indicators refer to easy repair sweet, but if it says call tech then bummer...

Please mention how many times standby light blinks on your KP-57WS520
There would be bit long pause between blinks so count the blinks and let me know to help you.

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.

Your description of the problem points to a power supply in the process of failing.
If it was mine, I would leave the set unplugged overnight, remove the back panel of the set, locate the power supply (likely on a separate board related to the incoming AC cable and will have larger components on it), look for an assembly number (often on a printed label), contact the manufacturer's service company and inquire about replacement or repair cost.
When you plug it back in, note whether it behaves normally at first turn-on. If is does, this tends to support the suspicion of a failing power supply since some of the passive components in it have had a chance to recover before weakening again.
Modern supplies are a good bit more efficient than 'linear' supplies of yore but are far more complex and much more dependent on quality of components.
