Which screw is stripped? A small slotted screwdriver (flathead screwdriver) can sometimes work. A small screw driver with a tiny dab of superglue on tip, hold to screw perfectly still, let dry, then unscrew. Take old plastic pen, heat till surface melts, press into screw head to make impression of screw head, let it cool-harden again, use as screwdriver to remove screw. Sometimes just a new screwdriver helps, because screwdrivers wear out, and a new one may have just enough bite to get the stripped screw out.
