iPad Air 2 has shut me out This is a replacement unit, replacing one that I dropped. I have been in the process of transferring my apps to the new iPad. I had finished yesterday and it was working just fine and then it seemed like it just stopped working. When I try to turn it on, I just get a black screen. I can access Siri and Siri answers verbally.  I know my user name and my password, which is coded number and fingerprint access, however I can't bring up a screen to enter it. 
Do you have any suggestions?
It is fully charged and I can turn the power on. Unfortunately the only reason I know it's on is that I can contact Siri but the screen is still black.
Definitely try a hard reset! I had the same issue with my iPhone - it worked fine - music was playing, the Mute Button would vibrate when I switched it to mute - but it had the slightly annoying fail that the screen was just black. A hard reset did the trick!
