I have a Nikon D40x that has been working fine for over 5 years now. It just recently quit on me with the error message "Press Shutter Release Button Again".. I have cleaned and lubricated the red shutter wheel on the bottom of the camera and it will work for a few test shots then quit again. Please I need help!
I have read some articles that lightly mention something about a mirror problem but I have no idea what to search for. If someone can provide a more specific article on mirror problems that would be great! Or any other ideas! Thank you
