Einleitung

This guide provides the steps to follow to disassemble the Canon Powershot SD550 down to the main system board. Removal of the main system board is required if the existing board has failed, is in need of cleaning, or requires maintenance.

    • Remove the battery and SD card from the camera.

  2. RcfWZ4sVXCwdHkJw

    • Remove the three 3.8 mm screws from the underside of the camera.

    • Each of the screws is slightly different, so it is important that you note the original location of each screw.

    • Remove the front of the camera body.

    • Be sure to keep track of the rubber ring.

    • Peel the navigation buttons from the button panel and set them aside.

    • To free the LCD display, remove the 2.9 mm screw in the top left corner.

    • Rotate the screen clockwise until it lifts away from the camera.

    • There are two ribbon cables attached to the rear of the screen. Do not try to pull the screen off at this point.

    After removing the screw, there are two metal hooks overlapping. Once those are separated, it was easy to lift the display. Also, this metal bracket kept falling off.

    • To unplug the ribbon cables, pull them straight out of their plugs. Do this gently to avoid damaging the connections.

    • After disconnecting both cables, pull the screen away from the camera to remove it.

    During reassembly, I had to remove the button assembly to attach the large ribbon cable. I had to remove these two screws (there is a hidden ribbon cable under the button assembly, be careful)
