This installation guide will help you remove the rear and front casing of your Nikon Coolpix 4600.
Locate the six screws on the outside of the camera (2 3.3 mm on the bottom, 2 5.25 mm on the left, and 2 5.25 mm on the right).
Using a Phillips 00 screwdriver, remove all of the six screws.
Carefully pull the front and back case apart.
Look closely at the connection between the ribbon cable and the motherboard. Locate the two grey tabs on either side of the connecting bracket.
Slide the grey tabs toward the bottom of camera. Gently disconnect the ribbon cable from the motherboard.
After disconnecting the data ribbon, you can now separate the back case from the front case.
