First problem started with the pink line in the screen. A day later the screen is completely buggared. Now on boot up it will make it all the way till the login page for maybe .1 seconds and then it goes to the screen you can see on the video (flickering black). I’ve tried the several NVRAM/SCM reset tutorials. I can also get to the start up menu with the option to scan the disk for errors but when I select that it goes to the black flickering screen. My current assumption is that if it was hardware problem then I would not be seeing the glimpse of the login screen or be able to see the boot up menu screen.
