A:Answer Facing the screen, there is a black screw at the top left on back of unit. Remove screw, plug on tab where the screw was, pulling outward and the screen should come loose at the top, Lean it out and pull upward, clearing connection which is at the bottom. To reinstall, put screen in bottom slots with it leaning outward at the top, aligning connection and push in at the top. Secure with the screw.
