Remove one screw and the carefully disconnect 2 ribbon cables and 8 cable connectors from the main board.

Remove the 6 video cable standoffs from the rear of the projector. Needle-nose pliers will loosen them enough then a Torx-8 driver fits perfect to loosen them the rest of the way

Carefully push the rear of the video ports inward to push the board enough forward and lift up.

Lift up and disconnect the cable connector on the bottom of the board to the power supply.
