Got the same problem. A short press on the power-button and the screen turns greyscale and then off.
If i press a button on the keyboard/mouse within ONE second it wakes up again. If it takes any longer than that single second the TV shows "No input" message and nothing turns the Pine back on. I can force-shutdown the pine by holding the power button for ~10sec. But just pressing the button does nothing.
I can allso mention that when forcing the pine off I can only turn it back on by pressing the "reset" button or unplugging and reinserting the powercable.
For the record I'm on Android 0216-build with my 2Gb Pine A64+
