Black screens in all aircraft

[AG_0113]

Hi,

I am new at X-flight.

When i start a new flight and turn on the master switch + avionics, all my screens are black.

So the instruments are not booting.

If I start in flight school, I have instruments on.

I am trying to start the flight with Pathera Pipistrel Aircraft, but after turing on master and avionics, the panels dont boot.

What to do?

Thanks for the answer.

BR, AG
