Answer to: LED backlight has a dark pattern on bottom edge of the screen?Hello. My name is German. Im from Argentina. I had the same problem, like in pics "LED BACKLIGHT 1, 2 & 3". I followed the instructions at Youtube "how to replace a MackBook Unibody display". See http://www.youtube.com/watch?v=taBKfR40x... Then I reassemble the machine and "voila". It works properly. May be a problem whit a conector or something like this. Try to disasemble and reasemble the data cable of the display before replacing it. Dont forget to disconect the batt. Regards.
