I was starting an experiment with my eVOLVER, and the screen on the evolver started to flicker with black lines going horizontally across the screen. It eventually went to fully black, but is still backlit when turned on.
I can run the evolver app from the computer, but can no longer use the touchscreen.
Did you jostle the eVOLVER around at all? Or tinker inside the machine? There is a blue ribbon cable that is attached to the touch screen. Check if that is loose at all.
