  1. Canon PowerShot SD450 Lens Assembly Replacement, Casing: stap 1, afbeelding 1 van 1
    • Remove the battery and SD Card from their slots. Leaving these in could cause the battery to ground and ruin the electronics.

    • Unscrew the six screws on the casing. Two are on the bottom as pictured; two more are on each side of the camera.

  2. Canon PowerShot SD450 Lens Assembly Replacement: stap 2, afbeelding 1 van 1
    • Pull the lanyard mount off of the camera using a spudger or your fingers.

  3. Canon PowerShot SD450 Lens Assembly Replacement: stap 3, afbeelding 1 van 2 Canon PowerShot SD450 Lens Assembly Replacement: stap 3, afbeelding 2 van 2
    • Find the line that separates the casing into its two halves. Hold each half separately, and gently pull apart.

    • Note that there is a small metal clip holding the two halves together. It might help to press down on the back half (indicated) while pulling upward slightly on the front half.

  4. Canon PowerShot SD450 Lens Assembly Replacement: stap 4, afbeelding 1 van 1
    • Take hold of the inside of the camera, and gently pull away from the back casing.

  5. Canon PowerShot SD450 Lens Assembly Replacement: stap 5, afbeelding 1 van 1
    • Remove the square, clear, rubber protector from the front of the logic board. This is not necessary to remove, but can easily fall off and get lost during later steps.

  6. Canon PowerShot SD450 Lens Assembly Replacement: stap 6, afbeelding 1 van 1
    • When you reassemble the camera, make sure the switch on the casing matches the position of the switch on the camera internals.

    • The black viewfinder padding can easily fall off the casing. Make sure you don't lose it when moving around parts.

  7. Canon PowerShot SD450 Lens Assembly Replacement, Logic Board: stap 7, afbeelding 1 van 1
    • Remove the LCD cable by gently prying the hinge open with a spudger or your finger. The cable should easily slide out.

  8. Canon PowerShot SD450 Lens Assembly Replacement: stap 8, afbeelding 1 van 1
    • Lift up the metallic-colored clip with the spudger to remove the shutter panel.

  9. Canon PowerShot SD450 Lens Assembly Replacement: stap 9, afbeelding 1 van 1
    • Remove the shutter panel with the spudger, now that the clip is released.

  10. Canon PowerShot SD450 Lens Assembly Replacement: stap 10, afbeelding 1 van 1
    • Use the spudger or your finger to release the orange ribbon from the logic board.

  11. Canon PowerShot SD450 Lens Assembly Replacement: stap 11, afbeelding 1 van 1
    • Pull the ribbon out of the socket using the spudger or your finger.

    • Disconnect the two other ribbons from the logic board in the same fashion.

  12. Canon PowerShot SD450 Lens Assembly Replacement: stap 12, afbeelding 1 van 1
    • Lift up the large green flap by using the spudger to pry up top right yellow edge.

  13. Canon PowerShot SD450 Lens Assembly Replacement: stap 13, afbeelding 1 van 1
    • Pull the flap back with the spudger so that the logic board is exposed.

  14. Canon PowerShot SD450 Lens Assembly Replacement: stap 14, afbeelding 1 van 1
    • Use the screwdriver to remove the three screws on the logic board. Take note that the bottom right screw is shorter than the other two.

  15. Canon PowerShot SD450 Lens Assembly Replacement: stap 15, afbeelding 1 van 1
    • Use the spudger to carefully remove the logic board from behind.

  16. Canon PowerShot SD450 Lens Assembly Replacement: stap 16, afbeelding 1 van 1
    • Remove the detached logic board from the camera.

  17. Canon PowerShot SD450 Lens Assembly Replacement, Flash Bulb: stap 17, afbeelding 1 van 1
    • Remove the side screw holding the flash bulb.

  18. Canon PowerShot SD450 Lens Assembly Replacement: stap 18, afbeelding 1 van 1
    • Remove the orange ribbon from below the lens.

  19. Canon PowerShot SD450 Lens Assembly Replacement: stap 19, afbeelding 1 van 1

    • Note that there is a capacitor in the flash bulb assembly, under the small circuit board. Do not touch the two metal terminals, as the capacitor may discharge. Damage and personal injury may result.

    • Use the spudger to carefully lift the flash bulb out.

    • Remove the screw at the upper right-hand corner of the LCD screen

  22. Canon PowerShot SD450 Lens Assembly Replacement: stap 22, afbeelding 1 van 1
    • Remove the function buttons by sliding the spudger underneath the black rubber and lifting up.

  23. Canon PowerShot SD450 Lens Assembly Replacement: stap 23, afbeelding 1 van 1
    • Lift up the LCD screen WITHOUT removing it completely. The screen is still connected to the camera via a backlight ribbon underneath.

  24. Canon PowerShot SD450 Lens Assembly Replacement: stap 24, afbeelding 1 van 1
    • Remove the last screw holding the tripod mount to the case. The LCD ribbon threads under the mount, so upon reinstallation, the ribbon will need to be threaded through before the mount is reattached. Take note of the tripod mount orientation.

  25. Canon PowerShot SD450 Lens Assembly Replacement: stap 25, afbeelding 1 van 1
    • Pull the back light ribbon from it's socket to remove the LCD completely. There is a little hole you can stick the spudger into to help release the ribbon.

This helped me fix my Canon IXUS 60. The lens was completely broken so I ordered a new lens module from ebay. Thanks to this guide I was able to fix it!
