Remove the battery before starting.

Screw management is key to a successful repair. I like using a series of bowls for each side or component of the camera, with scraps of paper to document anything unusual such as an extra long screw.

You'll need a small cross head screwdriver, and preferably a magnet stuck to the screwdriver to assist in picking up screws.

Optionally a silicon grease and lubricant can be used at the last step.
