The thin Ribbon Cable opens from the opposite side in which the Ribbon Cable enters. Open up the latch towards the Ribbon Cable. The latch will pull up and release the ribbon cable. Put your tool behind the black part, then pry up the black piece of plastic.

The wide Ribbon Cable opens from the same side in which the Ribbon Cable attatches, and opens away from the cable.

Both of these latches are the black pieces.

Gently pull the ribbon cables away from the latches. The LCD screen can now be removed.
