Tools

Step 1

Turn off the camera by pressing the power button above the LCD screen.

Step 2

Remove the two small screws on the bottom of the camera using a Phillips #00 screwdriver.

Step 3

Use a Phillips #00 screwdriver to remove the two small screws on the right side of the camera.

Step 4

Use a Phillips #00 screwdriver to remove the screw on the left of the camera under the A/V out digital label.

Step 5

Use a Phillips #00 screwdriver to remove the screw on the bottom of the camera near the battery and memory card slots.
This screw will be longer than the rest of the screws.

Step 6

Remove the front, back, and side casings from the camera and set to the side.

Step 7

Detach the LCD and backlight.
Remove the larger screw.
Remove the two smaller sized screws.
Remove the small screw.
Remove the small screw.

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.

Step 8

Remove the two screws near the the tripod mount using a Phillips #00 screwdriver.

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.

Step 9

Remove the screw next to the shutter on the top of the camera with a Phillips screwdriver.

Step 10

Remove the orange ribbon cable by lifting the ZIF connector attached to the ribbon with a spudger.

Need to remove another screw from lower right corner of main board cover (partially hidden by flex circuit) before cover can be removed.

Step 11

Carefully lift the shutter along with the ribbon connected to it. This will remove the casing around the motherboard.

Step 12

With the motherboard casing detached, remove the short orange ribbon by lifting the ZIF connector with a spudger or other plastic opening tools and slide the ribbon out. Detaching this ribbon will disconnect the side of the camera containing the motherboard from the rest of the camera.
