Hi - I brought my new D5100 home today and so far realy like it but I ran into a little problem, probably self induced. The camera worked fine out of the box and I was running through the menus etc getting familiar with the camera and then for some reason the monitor quit working, it works when accessing the menu, info, and looking at stored pictures but it no longer shows what I'm photographing, it's just black. The viewfinder works as it should. Any suggestions? As I said, it worked fine out of the box and for some reason now it's just quit working. I'm sure there's something I'm overlooking. Thanks.
