Display Backlight Does not Work
So about a year ago my brother dropped his 15" MacBook Pro (A1260) and the bottom of the display bezel cracked causing the display to lean back. The screen worked for a while before with the back light functioning while I ordered a whole new display assembly (I didn't want to have to rebuild the whole assembly). However after a few days the display back light stopped working but I chalked this up to wires becoming disconnected as the whole bezel was barely hanging on.
When I received the new assembly (it was tested and working) I installed it and all connections seemed to be fine. However, when I turned on the laptop the back light didn't come on. The start up chime happened and I could see a faint Apple logo.
I've hooked it up to an external monitor and it still works so it isn't a video card problem. I've reconnected the cables to their respected parts on the board and still nothing. I've read about the left I/O board causing problems but I haven't had any problems outside of the back light. Also I have red about the LED inverter causing problems but the new display assembly has been tested so I don't think this is a problem either.
I included a link to pictures of the logic board and stuff. Any help would be greatly appreciated.
