Blank Screen, No Backlight, Ok External
today after a small fall from a chair, even if the laptop was inside the protect shell and inside a laptop bag, my MBP started to have a completely blank screen, without backlight or images.
If I connect an external monitor everything works ok even if the internal monitor, from System preferences, is not recognized. All the service buttons work ok.
I tried to reset NVRAM and PRAM and switch on repair mode but none of this trials worked.
I think it's a problem of alimentation to the display, waht should I check? Could you link some guides in which I can see all the wirings related to the LCD?
Model No: A1286
Is this a good question?
