It seems problem with display lcd screen. Try to press on backside just below cemara there is lcd cable connector. it may possible that cable got loosen and that make your screen black. Alternately open back cover and remove side screw and reconnect your lcd display screen cable to circuit board. Try this [http://ipodtips-tricks.blogspot.in/2016/07/ipod-would-not-turn-on-black-screen.html|ipad wont turn on black screen]. this is usefull when there is no display or black screen but ipad iphone working.
