Macbook air 13" screen goes black while using iTunes

I have an early 2014 13" Macbook Air with a 1.4 GHz Intel Core i5 processor, and I'm using OS X Yosemite 10.10.1. When I'm using iTunes, specifically when I'm watching a movie or TV show, the screen will randomly go black, but not like it turned off. The audio still works, but I can't see the cursor or anything. The only way I've been able to fix it is to completely turn it off (control+command+power) and turn it back on. It happens pretty often though, and as you can imagine, gets quite annoying. Is there any way to fix this? Thanks in advance.
