    • Remove the 8.35 mm Phillips #00 next to the brown tab that holds the battery.

    • Remove the 1.75 mm Phillips #00 located at the top left of the LCD screen.

    • Remove the two 3.4 mm Phillips #00 located at the bottom of the camera.

    • Remove the two metal frames that hold the LCD panel in place.

    • The LCD screen should now only be attached by two LCD data cables.

      • Lift the screen from the left side and use a spudger or a small flat head screwdriver to flip the black portion of the connector upward to unlock it.

      • Carefully slide the data cable out of the connector.

      • To remove the backlight cable, use a spudger or a small flat head screwdriver to unlock the backlight cable.

    • The LCD screen itself can now be removed and fixed/replaced.

    • Remove the 1.85 mm #00 Phillips located on the left side of the camera.
