Question about Televison & Video
The quick flash and the on-off sound(Clicking noise isn't it?) indicates a faulty relay on the power board. A component level repair might be possible but you are going to need a service manual for this one more so its the failed protectors that knockout the relays more often than not. A component by component voltage/resistance measurement and comparing it with the values in the service manual are critical for this repair.
Unfortunately I don't have one for this model. See if you can find one online.

You could have a bad inverter board.
The inverter is the high voltage board that provides variable power to the backlight lamp. This is the most common. When inverter is faulty you can get no picture, or a very dim picture that can only be seen by pointing a torch light with a 45 degree angle on the LCD surface from very near distance.The inverter must be tested by reading voltages with a multimeter.
For this case, it would be best to contact the manufacturer or have a local repair tech to check it or replace the bad component for you.
Good luck and have a great day!
