How to Replace Parts on the Nikon D80

This article will show you how to replace specific parts on the Nikon D80 camera. It does not cover every part in the camera such as the mirror box, pentaprism, hot shoe, and other parts that require a lot of disassembly or are very difficult to replace. Some parts require calibration such as the shutter unit. The shutter can still be replaced but your shutter speeds will probably be off without calibration.

Steps

Replace the Bottom Cover on the D80

1. Remove the 8 screws on the bottom cover as indicated in the photo.
   
   
   
   
   
   
   


2. Remove the cover.


3. Installation is the reverse. Make sure the cover is fully seated.


4. Install all 8 screws. Note that some screws are different lengths.

Replace the Rear Cover on the D80

1. Remove the 2 screws on left side of camera as indicated in the photo.
   
   
   
   
   
   
   


2. Remove the 2 screws on right side as indicated in the photo.
   
   
   
   
   
   
   


3. Carefully work the cover off. The right side may be tight under the hand grip.


4. Flip the black tab up on the connector as indicated in the photo. This will release the cable. There is one ribbon cable connected to the main circuit board.
   
   
   
   
   
   
   


5. To replace the rear cover install the ribbon cable and flip down the black tab to secure the cable.


6. Carefully work the cover back into place. Don't force it. The screw tabs on the right go under the edge of the hand grip. Make sure the cover is fully seated before installing any screws.


7. Install the 4 screws on the two sides.

Replace the Front Cover on the D80

1. Remove the bottom cover as described above.


2. Remove the 2 screws on front cover directly under the Nikon logo.
   
   
   
   
   
   
   


3. Remove the 2 screws inside the flash cover as indicated in the photo.
   
   
   
   
   
   
   


4. Using a very small flathead screwdriver or pin, pry off the little round label on the AF/M switch. Hidden under the label is a screw. Remove it and the switch handle. The front cover should now be loose and come off easily. There are no wires connected to the front cover.
   
   
   
   
   
   
   


5. Installation is the reverse. Make sure the cover is fully seated before installing any screws. Check the AF/M switch to see if it is working ok.

Replace the Main Circuit Board on the D80

1. Remove the rear cover as described above.


2. Remove the 7 screws as indicated in the photo.
   
   
   
   
   
   
   


3. Flip up the black tabs on 2 cable terminals as shown to release the cables. Flip up the white tab on the larger cable and the remove cable. There are 3 ribbon cables.
   
   
   
   
   
   
   


4. Pry and pull off the 2 wire cables, one on each side of the circuit board.


5. Unsolder the 4 wires from the main circuit board. The circuit board is now free to remove.


6. Installation is the reverse. Make sure the wires are soldered to the right solder points.


7. Re-install the wire and ribbon cables. Push the flip up tabs down flat to secure the ribbon cables in place.


8. Install the metal cover and the 7 screws.

Replace the Sensor on the D80

1. Remove the rear cover as described above.


2. Remove the main circuit board as described above.


3. Remove the 3 screws as indicated in the photo. Carefully note the position of the sensor as it slides around a little when the screws are loosened. This may affect image quality when re-installing.
   
   
   
   
   
   
   


4. Remove the sub-circuit board with sensor.


5. Replacing sensor. Make sure the sensor is clean before installing. Try to position the sensor as close as the original. Install the 3 screws.


6. Install the main circuit board and rear cover. Remember to connect all solder wires and ribbon cables.

Tips

• Take the time to find a high quality philips screwdriver. The chrome tipped philips work better than the black tipped ones.

Warnings

• All cameras contain a capacitor used for the flash that hold an electrical charge. Most capacitors in DSLR cameras are about the size and shape of an AA battery. This charge is large enough to give you a shock, sometimes a very nasty shock. Once you take a cover off the camera touching any circuit board, wire, or ribbon cable could give you this shock, not just the capacitor terminals. To eliminate this charge and potential shock, first remove the battery. Then drain the charge from the capacitor. The best way is to use an analog multimeter set on 50 volts and connect it to the wires leading to the capacitor. This could also be the "+" (red) and "-" (black) terminals on the circuit board. Keep the meter connected for a minute to let the capacitor drain off its charge. You could also use a 120 volt light bulb, maybe an old working lamp with the cord still attached. The electrical plug should be replaced with some insulated clips. Just shorting the capacitor with a screwdriver could easily fry a circuit board in the camera.


• It is not recommended to try to remove the LCD panel from the rear cover. The LCD panel is secured with 3 screws that are glued in place and very difficult to remove without stripping the screw heads. If your LCD panel is damaged it is recommended to replace the rear cover with the LCD panel already in place.

Things You'll Need

• Jewelers screwdriver set. The most used screwdriver is a PH00 and a PH000 size philips.
