The shutter works but there is no picture that shows up. Nothing sounds loose in the camera. But either I dropped it in the past or I banged it. Again the clock is set right, the shutter works, just no picture and the error word is the problem
@mikeschultz the “err message” is commonly caused by a failed switch contact in the aperture control unit. Use this document Nikon D80 SM to work on your camera. A really good description can be found “err” message on the display, the answer is not clear
