Diagonal stripes on screen. MacBook Air

Hi. I have diagonal stripes on screen, they are kind of transparent gray and are visible on light colored background.

Diagnostic test doesn't find anything. It happened on Mavericks and after upgrading to Yosemite nothing changes. They are still there.

Tried to change resolution also, no results. MacBook Air (13-inch, Mid 2013)

Any advice would be appreciated.

MacBook Air, OS X Yosemite (10.10.1)

Try resetting the SMC (System Management Controller) Intel-based Macs: Resetting the System Management Controller (SMC) - Apple Support Make sure your mac runs an Intel processor, and make sure to follow the right instructions. If that doesn't help, try resetting the NVRAM/PRAM How to Reset NVRAM on your Mac - Apple Support Make sure to read all instructions carefully. I recommend you bring your MacBook Air to a Genius Bar at an Apple Store near you, so the techs can diagnose the problem. Even though Apple Diagnostics doesn't report anything, it doesn't mean it isn't a hardware problem. Also, if you take a screenshot, does the line appear in the screenshot? If no, it is likely to be a hardware problem, in which case you should take it to a nearby Apple Store. Take a screenshot by press and holding Command-Shift-4 and selecting an area with lines. It may be dead pixels.

I have the exact same problem! I bought my Macbook Air in May of 2014 and began noticing this problem around September just when I started school again. I have been meaning to take it to the Apple Store but I currently NEED my computer for school and can't sacrifice it being shipped off for weeks or even longer. Has anyone found a solution to this?! Or what caused it? I take such good care of my Mac so I can't seem to figure out what went wrong... although the lines are very faint, they bother me so much 😟
