First you system is likely still under warranty (one year for defective parts) so I would first visit an Apple Store to have them take a look. If that don't pan out then you could try reseating the camera cable on the logic board to see if that fixes it (I strongly recommend you do this after visiting Apple). Here, the IFIXIT guide you'll need to follow: [guide|38529] Follow the first three steps, then jump down to Step 23. Carefully remove it and then put it back in, reconnect the battery is it working now? If not you'll need a new display assembly as the camera is mounted within it and not easy to get to.
