iMac screen going black is a quite common malfunction when we use Macs. I have collected several high frequent scenes when the iMac screen turns black:
Scene 1. iMac screen goes black randomly, and after turning black, Mac will shut down automatically. When you restart Mac, it will get right.
Scene 2. iMac screen turns black continuously no matter how many times you restart it.
Scene 3. When you are doing something on Mac, for example, watching a movie, the screen goes black suddenly, but the system runs still in the background.
Scene 4. It is ok with turning on MacBook Pro plugging in AC adapter, however, when you unplug the power cable, the MacBook screen will immediately go black and shut down.
These four situations are not all about iMac screen changing black. But we can solve all of them with the following method.
