Getting Back to Default Panel State

I selected the "cold and dark" panel state, but now I would like to get back the panel state in the condition that the plane was shipped. How do I do that? I can't find a setting in the aircraft config file, and there is no default panel state defined. All of my PMDG 747's now start-up in the "cold and dark" state. I would like them to start running and ready for taxi.
