These 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. http://electronicshelponline.blogspot.com/
Blinking codes details to many popular brand TVs are given. Surf the site with patience. If blinks continue without any pause, the main board is faulty.

TV is broken,count the blinks,that is the service code

Here's the test to determine which board is faulty. With the TV on, as usual, shine a flashlight on the screen to see if there is a faint picture. If there is, then the ballast board for the backlights is bad. If there is no visible picture, then the T-Con board is bad.

Do you still have the tv?

it possibly you have shorted inverter board try to remove it and try again..if the indicator lit in blue replace it

Hi
Problem is probably PSU REGULATOR, STRF6668B.
I wouldnt recomend you repairing this yourself as there may be other components that will require checking.
You could end up blowing the replacement regulator.
