I have the 2017 Version and it was working successfully for awhile now.  Recently when I power it on, I have no lights going to the cockpit, rooms, or rear thruster lights.  The rear lights will just flicker one time when I turn the power on and off and then goes dark.

I have also used new batteries in my power source.

All of my landing gear lights work perfectly (separate control board).

On the small control board, it does power the small green light.  (Pic included)

My M. Falcon is stationary, doesn't move, and I only need to remove top panels to turn on power sources.  Do the control boards go bad?  I've probably turned the lights on less than 20 times total.

Need help.  Thank you.
