Dead Display, Unrecognized, but External Display Works
Bought this (a1286, 2.0GHz i7, 10.6) for cheap from someone who destroyed the display. Replaced the display as a unit with a Chinese remanufactured one. Worked fine for about a year, then display died. Internal display never even flashes and is not recognized by System Profiler. Reseating LVDS cable on motherboard didn't help, nor did resetting PRAM and SMC. Shining a flashlight on black screen doesn't reveal anything. However, an external display works just fine.
Heard things about a tiny fuse or driver on the board, or even the DC-in being the culprit (but the battery charges).
My next step would be to get the glass off (what fun!) and see if the LVDS cable is properly seated within the display assembly. Maybe just replace the cable when I'm in there.
Thanks so much!
