You may have a build up of dust.  This can cause a short in the backlight circuitry or possibly other circuits.  Use an air duster and go to every vent you can find.

 

If that does not help

check warranty and call for repair info:

If out of warranty then review this video

Removing the screen would allow better access to the air duster but I suspect there is a hardware problem.
