    • The LCD screen and housing should now be in three pieces:

      • LCD screen frame

      • Begin by using the Philips #00 screwdriver to remove two silver 0.159in screws on the top and front of the camera.

      • Remove the connector from the logic board and detach the release button housing from the camera.

    • With the plastic housing for the release button removed from the camera, use the Philips #00 screwdriver to remove two silver 0.090in screws.

      • You will have to lift the Function button and its wiring up from the pins holding it in place to access some of the screws.
