There are two ribbon cables: a wide one for the lcd display itself, and a thin one for the backlight. When reassembling, it is easy to reverse the polarity on the backlight cable, in which case the backlight will not work. Make a note of the polarity as you disassemble.

On some versions of this model, removing the back cover will suffice for this repair. The back cover is secured by only six screws.
