Hi guys. So this evening i opened up my mac and the screen was totally black. I could hear the sounds of the OS in the background, but no visual response. I then proceeded to hard reboot the machine, and was frightened when the attached image was displayed. It looks to me like it's a corrupt GPU, or something to that affect. The LCD is 100% intact. I did get the display replaced through my insurance 6 months ago, and this is my only chance of having it covered on warranty, since it expired 6 months ago. It could possibly be the connection between the display and MB, but i can't manipulate it by moving the screen. Retina Macbook Pro 15" (late 2013) with GT750m OS X 10.11.3 What do you guys think?
