After a photo-shoot, I kept my Nikon D5100 inside its cover and at the top of closet. Unfortunately it has fallen down. The height was about 7' (about 2 meters).
I didn't hear any breaking sound as it was kept inside its cover. However, I checked instantly and it was seems ok. Next day when I put its power on, it was showed in the display- " Error! Press shutter release button again". What I do now?
