Blinking screen on Macbook Air 2011 13" I have some issue with my macbook air mid 2011 13" One day screen start blinking and flickering. This is a short video how it looks like click Only blinking, no stripes on screen or other artifacts.

Any suggestions what is the reason? Screen, motherboard, I/O board? How can I fix it without changing the screen?
This definitely is a screen issue with the backlighting failing. Your only option will be to replace the screen.
