CRT'S go blank after 50 seconds

[Guest trouble]

After starting PMDG 747-400 FSX everything works well, then all 6 CRT screens go blank 50 seconds later. Other airplanes such as B-737 operate normally.....................................................................................................................................................................................................Using Windows 7, 8 Gig Ram, 64 bit operating systemHelp please,D.

Do you possibly have a bootleg copy of it?

That used to happen to my FS9 PMDG 747 when it wasn't registered properly. so I'd perhaps look into that and make sure it is installed okay and such.Al

Do you use the cold and dark panel state from PMDG?Do you load a FSX standard plane before loading the complex 747?I have had weired behaves, too, because self-saved panel states or other complex addons where loaded before the PMDG planes.So try to load the cold and dark predefined panel state and see if this helps....
