Not sure what is wrong here. If I load the default flight (saved cold/dark) switch to the CS777, I can power the APU or ECU, start the engines, switch lights on etc etc BUT the MFD then shortly goes semi blank and the PFD usually never powers on fully.

IF on the other hand I use the default "ready for takeoff at SEA" all works normally.  I always like to do the full power up procedure and there shouldn't be an issue with this very common way to enter FS with this a/c. Thanks for your guidance.
