Interestingly, is it possible to turn on the FCU panel only after power is supplied on board?

USB has the power line as well so if the unit you use doesn't reqire external power supply, the only option to turn it off/on would be to connect unit via USB hub with power switch for socket

I think op meant how to turn off the FCU displays when there is no power in the virtual cockpit.

Then you should tell us what aircraft and what sim you want to achieve this

Boolean Lvar, true if FCU has power

#

Create an output for this Lvar in Mobiflight

#

Use this output as config reference in each output config that needs to be off when FCU has no power

#

Add a Transform
if(#=0,' ', $)

#

This will set the output to a value of blanks if there is no power in the FCU.

#

For led annunciators in the FCU you would substitute the blanks with a zero.

and for backlight you can do a Transform with $*# so the backlight brightness is whatever the simvar is ( $ ) but if fcu has no power ( # = 0 ) then the value is 0, because anything * 0 is 0

it doesn't work out, maybe something else needs to be prescribed, specified?
