I have an old MacBook Pro 13" 2013 Retina pro that I would like to get working. It has developed vertical lines on the screen (see pic). It is fine plugged into an external monitor, which makes me think it is a screen problem, rather than a logic board problem. I have had a look about inside and can't see any loose cables, etc. I haven't dropped it or cracked the screen as far as I can tell.
Any help greatly appreciated!
