sounds like the LCD backlight isn't working. you may want to check these connections on the motherboard and on the LCD panel for the LED back light. Also, you may want to connect your old display to see if the problem is reproducible. Tim
If it is cracked along the edge near where your palms rest you be able to get it replaced under warranty. Several others have had the same issue. Try to visit an Apple Store and see if tehy'll replace it for free.
Note on the two ZIF connections. The smaller connection has it's ZIF lock toward the front of the laptop while the wider ZIF connection faces the KB. I busted the keyboard connections thinking the ZIF was in the opposite direction. Had to replace it with a new trackpad.
I have found that I was able to wiggle the cables out of the ZIFs carefully. idk if this works for all ZIF connections and I'd love to hear anyone who has an opinion on removing ZIF cables. But this makes it much easier to remove and not break the ZIF connections.
What about the random USB port or two SATA connections? What are they used for?
Is there a chip on the device that would support Wifi? What is more power friendly: BT 4.0 or Wifi? So many questions!
