Question about Nikon D40x Digital Camera
Even when the lens is properly attached, it says 'lens not attached'. I've checked the contacts and attachment, and it intermittently works. How do I fix this please?
We had the same problem. After inspecting the contacts I saw that the one metal ball (contact) that was separate from the other contact grouped on the mounting collar was stuck down. By pressing the contact a couple of times with a blunt object it freed up the contact so that when re-attached the lens it worked as expected.

If you switch to manual operation and the error message is no longer showing and you are able to take a shot ,it would appear a contact problem on the lens or camera body.
Those little gold plated pins must be spotless.

The contacts can be cleaned if you "VERY CAREFULLY" use a clean eraser on both the camera and the lens. Be extremely careful that you do this with the camera facing downwards, as you don't want eraser bits to find their way into your camera. Also clean the contacts on the lens. When you change lenses, always point the camera in a downward position, as this keeps dust and other stray particles from entering your camera and sticking to the high pass filter. If this doesn't work, I would take it to a Nikon approved repair facility.
