I have a the same problem with my touch screen, I had to search out this post. . . I did not want to start another one. With only the touchscreen plugged in, no air mouse or keyboard, JUST using it as anyone would use a tablet, if I let the screen time out, or if I short press the power button to turn off the screen there is NO WAY to turn it back on other then turning it all the way off then turning it all the way back on. I am not sure if it is locking up, or what, but the power button should turn the screen back on and it doesn't I will try with a wired keyboard and mouse to see if that solves the problem, but it really is SUB ideal for a tablet situation which is what I want to use one of my pines for when the case is available.... the screen doesn't hold the camera unfortunately the camera slot is to small on the screen... but that is not a deal breaker, but this inability to turn on screen is.
It appears that if I turn off the screen and turn it back on quickly within say a couple seconds it comes back on. After five seconds ( I counted mississippi's) it goes off and stays off. I can not turn it on with the keyboad, mouse, or power button. Hitting reset will reboot the unit.
