What's wrong with the screen on this MacBook air
This is technically a 2017 MacBook air (A1466, EMC 3176) but it is essentially the same as a 2015 model so I'm posting it here.
I've purchased this MacBook used off a friend of mine. This is what it looks like.
It has vertical and horizonal lines going to the display but the lcd itself isn't cracked. I unpluged the display cable and plugged it back in and it didn't seem it do anything. Is my display broken or is the display cable broken and what part should I get replaced?
FYI: The seller said that the screen broke after he ran with the Mac in his backpack. It must have hit something hard inside the bag and broke it.
