Hi all, my name is Luis and I have a Macbook Air from 2010 and I have really weird problem with the screen. The OS boots totally fine but the screen is totally black, no brightness. In the beginning I thought the screen was totally death, but I took the Mac outside and notice that with external light you can almost see all in the screen. Also if I used a flashlight and I can see everything on the screen, and of course I tried to get to the max the brightness configuration but no change at all. I have took the Mac to an Apple Store and connect it to an external monitor and no image at all. Maybe a faulty Motherboard or faulty video card or perhaps a loose connection screen cable? I don't have much knowledge on how to repair this or maybe if I can. Any suggestions or maybe someone had the same issue? Many thanks for any reply on this.
