My isight camera, light sensor, and keyboard backlight are working?

I have this problem too, and could offer you this advice. On 2010 Unibody MacBook Pro models, the iSight camera and ambient light sensors are together on the same cable. I recently switched out my optical drive for another hard drive and in the process accidentally broke this cable, so I know exactly what the issue is. I know this post is old, but I figured I'd respond anyway.

Hi, Im pretty sure this is a old thread, however, I recently had this problem and just wanted to contribute. Same deal stripped screw, two of them actually on my logic board. (of all the places right? X_X) There are tools that could take the stripped screw out, however, I really did not want to spend that money, plus I didnt have it. So my solution was to take the smallest drill bit I had, and basically drill a little in the head of the screw, then changed the drill bit to the next biggest, and continued that until the top of the screw came off. For me, it took around 10 minutes of careful work, switched at least 3 bits before I was successful. The key to this is to be very patient and to drill lightly so that if you slipped, you would not be drilling through whatever was precious (ie in my case the logic board) So yeah, hope this helped!
