    Could be any number of things.  Something failed on the monitor (power supply perphas).  Maybe the cable fatigued and a wire broke inside.  Maybe your video card has failed.

     

    In other words, too many variables.  You need to eliminate them as best yo can.  Try the monitor on a different computer.  Try a different cable and/or check cable connections.   Try another monitor on your computer.

     

    Try a smc reset but it probably won't change anything.
