Grasp the camera and upper LCD ribbon cables between your thumb and forefinger, pulling them out of the upper case slightly, slide them down through the slit in the upper case.

Rotate the front bezel assembly clockwise so that the ends of the camera and LCD cables slide sideways through the slit in the front bezel.

In order to remove the upper LCD and the cameras from the front bezel, it is helpful to coil the ribbon cables together.

Carefully coil the two ribbon cables together, so that the connectors are on the inside of the spool.

Wrap the ribbon cables tightly, but not too tight, as bending the connectors will render them inoperable.

Holding the upper LCD and the cameras together, pull the cables through the hinge in the front bezel.

Pull slowly, making sure that the cables do not catch on the hinge pin and tear.

Uncoil the ribbon cables.
