  • Once the LCD and Backlight are detached, remove the larger screw marked in red in the picture as well as the four smaller sized screws marked in blue.

On my camera (SD700) there were no screws where yellow circles are. There was a total of 5 screws in this step which should be easy to spot. It is important however to keep track of which screw goes where as there is 3 different size screws in this step.

  • Remove the two screws near the the tri-pod mount with a Philips head screw driver.

One of the 2 screw locations in diagram is wrong. One screw goes through flex circuit but the other screw goes in the hole in top left of picture closest to LCD assembly.

I should clarify - the second screw goes in the hole just above and left of tripod lug hole.
