The control cable can be replace ($6 part). Be careful to double check the orientation when re-soldering to the board. It's easy to put it on backwards.

For the re-install, the cables that run along the sides of the LCD display do not follow the entire length of the display on either side. Both the iSight cable and the Airport antenna cables come away from the sides of the display about 3" from the corner where the hinges are. They move to the outside around the aluminum hinge supports. This is important so the cables do not get pinched and the bezel can snap into place.

The ground screw also holds down a ground loop that is part of the speaker cable. The two loops may be stuck together so you need to carefully separate them.
