Hold the power button and home button until the apple logo show. If it still black screen then I think you install uncompatable tweak on your device so try holding home and power button until apple logo then press the volume up "+" (that safe mode) then if your on safe mode go to your cydia and uninstall that make your iDevice black screen

Try hard rebooting your iDevice they way Kenny said so, if that doesn't work, boot into safe mode.
