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.
how many blinks does the red light give in a row? This would be an error code?
The problem for 7 blinks would be an Interface board. Apparently there is a glitch in the interface board that sends signals to the television.
Basically the glitch shorts out the board and the t.v wont turn on and
you will see the power light blink 7 times pause then 7 more. You can
replace the board with a new one and update the software on the new interface board.
If is isn't 7, let me know and I will help you out with this

hold down the input button and volume - while the MAIN POWER BUTTON IS OFF. Then turn on the main power button while those are held down, the light on the tv & avc box will turn green, then immediately let off the 2 buttons and press volume +. Next step is to repeat the process about 20-40 times & the TV WILL WORK!. I have read that this may have something to do with the energy star compliant commads that can changed through the serial port.
