Hello, in the last flight my skyview lost the adhars information, I made a hardware check and the adhars was not in line, check the wires and everything is ok, when I try to power up the skyview again it not boot, just a black screen with a white cursor in the top left corner. I tried with the main bus, and with the back up battery, I disconnet the back up and the same problem. Any idea what the problem is? thnak you.
