I had a similar event happen on June 20. After fueling up I started to taxi out, and turned on power to the IFLY. I was presented with a white screen that immediately went to black. Disconnecting power and then plugging back in initiated a blank stripped screen. I took the IFLY from the plane into the FBO and plugged in with the wall adapter, but no change. The IFLY was in the aircraft for approximately 20 minutes with the sliding cockpit open, but it was sunny. However, it was only 9:30am. After having the IFLY in the FBO for an hour, there was no change in the screen. I stowed the IFLY and flew on to my destination. Later that evening I plugged in the power, and the screen came up normally. When I departed 3 days later, the IFLY functioned normally. I have contributed the glitch to heat, even though the temperature on the tarmac was not much hotter than the previous 1.5 hour flight. Has the company responded to anyone about this issue?
