Question: Macbook Pro 13.3 Retina flashing display.
Hi. I've already booked an appointment to get my laptop checked but it's not for a few days so I'm super anxious.
The problem is that my screen keeps randomly flashing and glitching. It flashes colours in a diagonal pattern. (see attached photo).
What happens is that it will keep flashing this but when i touch the trackpad or type again, my computer seems completely fine. Just when it's inactive for about two seconds, the glitching will comeback and not stop until you do something. When plugged into my external monitor, the flashing does not occur. It's just been happening for a couple of hours at this point.
How the problem started is that I was using my laptop then suddenly the display went black (like turned-off black) then I restarted my computer a couple times and got to this stage.
Please help, I'm having very high anxiety because I have a bunch of assignments do all of which that absolutely REQUIRE my computer.
Thank you to anyone that can help.
MacBook Pro (Retina, 13-inch, Mid 2014)
