I have a Macbook Air 11" from mid 2013 model updated to the latest update from Mac OSX Mavericks v. 10.9.2. I have tried to SMC reset and NVRAM reset, but without any luck.

When I turn the power on and after Apple logo during boot up - comes a quick flicker on the screen.

I have uploaded a video - showing the flicker on the screen during boot up.

I hope somebody in here can help me with this issue.
