Those flashes are fault indications. If you wish to get more details visit the site linked here. http://electronicshelponline.blogspot.com/ Blinking codes details of many popular brand devices are given.

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 of many popular brand TVs are given. Surf the site with patience. If blinks continue without any pause, the main board is faulty.

Sounds like main digital board fault. These blinks [flashes] are fault indication (Error Codes).

Sounds like a backlight is out. If its still under warranty, exchange it. First try unplugging it for two minutes to reset the t.v.

The Search Method
If your device does not respond to the TOTAL CONTROL after you have tried all the codes listed for your brand, try searching for your code. The Search Method allows you to find the code for your device by scanning through all the codes contained in the memory of the TOTAL CONTROL.
To search for your TV code:
1 Switch your television on (not on standby) and aim your TOTAL CONTROL at your TV.
2 Press the TV key on your TOTAL CONTROL.
3 Press and hold down SET UP until the red light blinks twice. (The red light will blink once and then twice)
4 Press 9 9 1. The red light will blink twice .
5 Now slowly, alternate between POWER and TV, over and over, until your television turns off. You may have to press these keys many times (up to 150!), so please be patient.Remember to keep pointing the TOTAL CONTROL at your television when you press these keys.
6 As soon as your television turns off, press SET UP.
The TOTAL CONTROL remote should now be ready to operate your device. Turn your device back on and try all the remote’s functions to ensure they are working
properly. If some of the TOTAL CONTROL’s commands are not operating correctly, try the search method again. You may be using the wrong code.
Once you have Set-Up your TOTAL CONTROL, you can blink back your SET-UP CODE for future reference.
Example: To blink out your Television code:
1 Press TV once.
2 Press and hold SET UP until the red light blinks twice (The red light will blink once and then twice).
3 Press 9 9 0. The red light will blink twice.
4 For the first digit of your four-digit code, press 1 and count all the red blinks. If there are no blinks, the digit is "0".
5 For the second digit, press 2 and count all the red blinks. If there are no blinks, the digit is "0".
6 For the third digit, press 3 and count all the red blinks.
If there are no blinks, the digit is "0".
7 For the fourth digit, press 4 and count all the red blinks. If there are no blinks, the digit is "0". Now you have your four-digit code.Make sure you write your Television code for easy future reference.

This blinking is a diagnostic code. Please update this with the model number. These sets contain circuitry that will shut the set down and display a code like this when a problem is detected. With the model number, I can look up the problem and provide potential repair suggestions.

Thanks,
Dan

TO PROGRAM THE remote USING THE 3 DIGIT CODE:
