My panel consists of a D100/D120, HS34/AP74 autopilot, and GARMIN 496. The D120 is energized when I turn on the master switch, but the display stays blank for a couple of minutes before it shows the EMS parameters. It seems to be less of a problem in the summer heat than the winter cold. Does anyone have any ideas what the problem is and how to fix it?
