Is this a good question?
Have you proved that the LED backlights are the problem by connecting an external monitor to the laptop's HDMI port and check if there was a display on it?
If there is a display on the external monitor, with the display switched back to the laptop screen, shine a torch (flashlight) at an angle close to the screen and check if you can see any images on the screen. They will be very faint if they are there to be seen so trying in a darkened room may help
If you can't see images then the screen or the video cable may be the problem.
If you can see images then the backlights are the problem.
This could be the motherboard, the video cable or the screen itself. What is the make and model number of the motherboard as printed on the board itself?
