We need indeed more information to debug this.

Do you get any shutdown messages from systemd when you shut down? If so,
please snap a picture and attach it to the bug report.

If the screen stays completely dark, it might help to switch to the
console (CTRL+ALT+F3) and shut down from there. Sometimes display
managers interfere and don't chvt.

Please also follow the hints in
/usr/share/doc/systemd/README.Debian.gz (Debugging boot/shutdown problems)

See the section starting with "In situations where the debug shell is
not available,..."
