PMDG 747-400 Problem

[Gunhaver]

Hey all..I'm having a problem with my PMDG 747.  I've tried looking up a solution online and have come up empty handed.  The problem is, i start up everything on the overhead panel but my PFD or any screens for that matter wont come on!  I've tried adjusting the brightness, I've looked for an avionics switch I may have missed, I cant find anything..Here are screenshots of my overhead before, and after...maybe I'm doing something wrong, or maybe it's a file problem?  Sometimes, they will show up when I fist load the simulation, but then when I open a panel or switch views they go off.  Anyone else having this problem?

Before startup:


After startup:

(1) Battery on
(2) Standby to Auto
(3) APU to run
(4) Wait til APU Gen 1 and APU Gen 2 light up as available then select them

or use external power....

Should light up by this stage, if not uninstall and reinstall.

Try adjusting the dome light, glare shield etc to the right too, see if anything lights up-it should do.  Make sure you`re fueled up too and all fuel switches selected where necessary.  Carefully read the cold and dark section of the tutorials.  It has to be exactly the right order.
