Hi I fell on my Macbook pro early 2011 and the screen broke. The backlight was still working but the frontglass and the lcd where broken. Now I bought a used screen that turned out to be from a 2010 Macbook pro. There was one wifi connector less than my model but still wifi works well. However the backlight does not come up. The lcd works as I can see with a lamp behind the screen. My question is where to look for. Was the backlight broken in the first place or is there some incompatibility with my model and the 2010 model? Should I check for the fuse on the logic board?
