  • Remove the four highlighted 3.0 mm Philips #0 screws on the bottom of the camera.

Worth mentioning, the top circled screw was a 6mm on my camera. The other 3 were 3mm.

  • While pulling the bottom down, remove the back of the camera.

  • Be careful not to pull too hard on the back as it is connected via a ribbon cable. Be sure to disconnect this cable on the main board.

  • To disconnect the ribbon cable pull the small black tab upward and pull gently on the cable.

What is the ordering of the small wires on the bottom? It is hard to put back together from the photos. Thanks!
