Closely follow directions when disassembling the Nikon D40 camera.
The Nikon D40 is a digital, single-lens reflex, or D-SLR, camera. Before disassembling any digital camera component, you should ensure that the working environment is as free from dust and dirt as possible. Disassembling a Nikon D40 body is a fairly straightforward process that provides access to the circuit board and image sensor. From there, the image sensor can be cleaned or modified. As with any electronic device, opening the camera body will void the manufacturer's warranty.
Instructions
1. Remove all the screws from the bottom of the camera using the Phillips head screwdriver. Place all screws in a small container as they are removed so they are not misplaced.
2. Remove the bottom plate and set it aside. Turn the camera over and remove the eye cup around the viewfinder.
3. Remove the two screws on either side of the camera and lift up the rear LCD panel and disconnect the cable. Set the LCD panel aside.
4. Turn the camera bottom up again and remove the screw closest to the I/O cover on the side of the camera. Remove the I/O cover and set it aside.
5. Desolder the two visible joints on the exposed back of the camera using the desoldering wick or gun.
6. Remove the screws holding the metal shield in place. Pull off the shield using the tweezers and set it aside.
7. Disconnect the five cables and remove the three screws from the circuit board. Carefully lift the circuit board with the tweezers and flip it over to the left. Do not pull the board away from the camera, as it is connected by a soldered joint in the lower left-hand corner.
8. Remove the three screws holding in the sensor assembly and carefully lift it out of the camera body. Disconnect the cable and place the assembly on the microfiber cloth.
9. Use the canned air to clean out any dust and dirt from the body, circuits and sensor assembly.
