hello, I don’t speak english very well. I have resolved the same problem by make one bridge on the backlight fuse (macbook pro late 2008). It’s easy ! I have test the fuse by an multimeter before make the bridge. Have you search on google with “macbook pro 2008 fuse” https://forums.macrumors.com/attachments...-jpg.600752/ https://forums.macrumors.com/threads/mac...-pro-backlight-fuse-locations.1629823/
the webcam is ok ? i have already have this problem : the cable which connect to the logic board was a littel broken. on my imac 17 intel core 2 duo, this cable is for the webcam, the micro + the speakers. (and IR i believe). Update: it's the cable we see under the Superdrive on this picture : http://guide-images.ifixit.net/igi/gEoIZjoREXseLI5p.h... on my imac core 2 , this cable is an other place. (you can follow the IR cable to see the connection witj logic board.
