It happened to me from out of nothing to get a black screen in mac. I went directly in google to inform about this and the solutions with Pram and so on didnt work. I tried using an external lcd and saw that it worked normally just the screen is black. If i turn the brightness high it goes a little blue but i dont see nothing. It even detects the screen at display. I dont know if it is a software problem or maybe the cables connecting to the logic board have some problem. Any suggestions? Should i reinstall os or maybe is it hardware? Actually i am using this mac right now :)
Shine a light through the Apple logo and see if you can see anything on the screen. Also use a known good test screen if you can to see if it’s the screen.
I think you should try reinstalling the software. If this doesn’t work, be sure that everything is secured inside correctly. If all else fails, it’s probably the hardware. Get Apple to help if this doesn’t work.
