I found my old D80 and tried to take a few pictures but it doesn’t work.
* Viewfinder is dark
* Live View doesn’t turn on.
* When half-press shutter-release (trigger autofocus) Err starts blinking. Goes away after a while.
* When fill-press shutter-release I hear a motor buzz but nothing else happens, no AF, not shutter, nothing.
What might be the issue? Is it hard to fix?
