If your TV is less then a year old, still under manufacturers warranty. If not under warranty the defective parts could be the power supply or the back light inverter board. Both boards can be replace easily.
The way to know if you have a defective backlight inverter is by shinning a light from a flash light near the screen with the TV on and check in a 45 degrees angle if you have a dark video in the background, if the video is present then you have a backlight board failure. If no video, then is a power supply failure.
I have both boards if you want to buy them.
Let me know if you require further assistance.

Look at the power supply, see it you can actually see any damaged components first, check the main AC fuse, burnt parts, etc.
