Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.
If blinks continue without any pause, the main board is faulty.

Kinda points to power supply . Does it start normal for a short time or refuse to start ? Bad capacitors are a common problem in the past , doubt that is cause here but on bench I always run the ESR meter around the power board at least .
You could have a bad CCFL but this young not likely . Did you have a power surge or lightning strike nearby ? A UPS is always a great investment not just a surge bar .
Make sure you power cycle...ie:pull plug from supply and let sit 15 seconds at least . Then try again .

Just some thoughts with out more info .
