Question marked as
That sounds like either the backlight has failed or the display itself has failed. Please try restarting in Safe Mode per the instructions in Safe Mode. If that fails, please take it to your local Apple Authorized Service Provider to have it serviced. Remember if the iMac is a 2015 or order it is vintage and an Apple Store will not work on it, however you may have an independent Apple Authorized Service Provider in your area that will.
