I too had this problem (twice) with client computers. In both cases (for me), replacing the backlight cable that connects from the logic board to the inverter, fixed the issue. It's also worth noting that you don't have to completely remove the optical drive, display, etc as the iFixIt guides show. You can simply pop the top cover off and remove the LCD bezel and go from there, saving lots of time.
