Hello! I have a problem with the PFD and ND also. If it starts with the engine running those displays go off after not more than 1 minute. If in cold and dark, after energizing the apu gen, they remain blank! What's the matter?? I have Windows 7 with Xplane 10 and version 1.4.1 just downloaded at xplane.org and already registred! Thanks for the Help! Stefano
