Hi.
I am having the problem that the screen is not turning on for the GTN 750. When I turn the battery/avionics off the screen goes a bit darker so it seems to react. But when I turn the battery/avionics back on the screen stays blank.
I sometimes have luck that after constantly turning it off on on again that it works but that is very frustrating. Whenever I try to turn it on the log reads:
17/11/19 09:36:13.635 13560 ERROR] Trainer Failed Task: 00000001
17/11/19 09:36:13.684 13560 ERROR] Die angegebene Prozedur wurde nicht gefunden., code: 0000007f
I use the steam version of X-Plane 11.05.
Regards
Silvio
