Answer to: All operative but with black screenI had the same problem. Mine was hardware related. The ribbon for the lcd somehow became dislodged enough to cause the screen to no longer function. I'm guessing from my kid dropping it. This device is super easy to open. There are videos on YouTube on how to do it. After removing the innards from the bact casing it was as simple as reconnecting the ribbon cable. It hasn't been an issue since. In fact I'm typing this on my 10.1 currently.
