Your system has a Hall sensor which senses the magnetic flux from the magnet held in the display lid along its front edge.
Its been awhile since I've worked on these so my memory is a bit foggy. I do believe the sensor is located with in the uppercase assembly. So using a steel paper clip first locate the the magnet hidden in the lid rubbing the paper clip along the face surface along the edge.

Once you've located the magnet carefully fold down the lid to transfer the location to the uppercase (use some tape to mark the spot). Then follow this guide [guide|515] to remove the upper case to then locate the Hall sensor. So either the connection within the upper case is loose or the ribbon cable has become damaged (likely). Try reseating it and if that fails replace the cable and then if that fails its time for a new uppercase.
