The Nikon D80 was released August 2006, now thirteen years old; thus in camera years quite old. When I owned my D80 it was outstanding camera used on many pro shoots. After a few years it gained an attitude so I purchased another camera. It could be your D80 is giving up the ghost; it is old. Please recall, all digital cameras are disposable, when the electronics go out dispose of it, having it fixed will cost more than expected and certainly not worth the effort nor cost. Also, it may be extremely difficult finding parts.
