Hey guys, I have a late 2010 model MacBook Air. Half of the screen on the left is dark and the right is a bit lighters. The main problem is every now and then a section of the right screen, about 2 inches wide and all the way from the top to the bottom of the screen gets this weird line sensation going through it like the screen is broke. It goes away and that section acts normal then comes back. Do you guys think this is an LCD, logic board or cable problem?
