Start with a factory reset. Its unlikely that will fix it, but its the easiest fix. If that doesn't fix it, open it up and check the LCD connection on the motherboard. Make sure its seated will and there is no debris in there. Test the screen before you reglue the digitizer. I'm posting this as a comment because I ran into a few Airs that gave me this same problem and I never did figure them out. Hopefully its something simple that a reboot or reseating the connector will fix.
