    Specs:
    2013 Macbook Air SSD
    iMac Black Screen On Bootup
    I started up my iMac today and heard the chime but all I get is a black screen. I've tried unplugging all cables, Resetting PRAM (Which did not work, only get one chime) Any suggestions? Here is a video of what happens when I start it up

    Specs:
    Late 2013 27" iMac, iPad 3, iPhone 6s+, iPhone 6+, 3 iPods, El Capitan
    Do you have a spare monitor or TV you can hook up to your iMac? That would tell us if there's a problem with the iMac display, backlight, or graphics card. Try using a flashlight and shine it directly on the iMac display to determine if there is any video present.

    The good news is that now I got the display to turn on but after a while it turns off and then I cannot get it to come back on anymore

    Specs:
    Mid-2012 MBP (16GB, 1TB HD), Monoprice 24-inch second monitor, iPhone 5s 32GB, iPad Air 2 64GB
    I would take this to an Apple Store or Apple Authorized Service Provider.
