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.

The registration card may help with warranty going through the TV company. But, that's the last option.
You can fix it yourself by replacing this board. The board number should be BA71G0F01043.
The 8 Inverter transformer are the problem. They are on many TV power boards that are causing the same problems.
Ebay is selling a couple for $49. Good price I think.
