Is your lens seated firmly on the body, and the lens aperture ring set to minimum aperture? Do you have a memory card in the camera?
Tried removing the battery and reinstalling it?
My D200 did this after I subjected it to -55degC. It finally seized and produced ERR. After I warmed it and removed the battery I heard a click of the mirror re-seating and put the battery back in and it was all good again.
But yes otherwise it does sound like it may be dead.
You do realize that the body isn't warrantied for those conditions, don't you?
The Nikon will be fine, I mean yours!![]()
