    • Next step is removing the PCB. I made the mistake not to take care about the battery compartment switch. If you are not careful, the black lever will break off. Not a problem though, because then the camera will work also with opened battery compartment

    • Remove main PCB by slightly bending outward the cover for the jack with fingernail. Now lift the PCB slightly upwards.

    • Re-attaching the connector is not easy. I used a small screwdriver to carefully press the connector back in place.

    • Note: This is not the official method to do this. Normally the Top cover and several other parts need to be removed too.
