Introduction

If the camera does not boot despite the battery being hail and hardy, there could be a fault on the main printed circuit board. Use the following guide to replace the main printed circuit board.

    • Remove the four indicated 3.0mm long black screws from the bottom of the camera and the viewfinder housing using a PH0 Phillips screwdriver.

    • There are four screws on the bottom of the camera. Only remove the two nearest to the screen.

    • Remove the viewfinder eye cup by pulling up and out from the bottom to separate the locking clips from the camera.

    • Do not flex the eye cup too aggressively as it may lose its shape.

    • Remove the two indicated silver 3.5mm long screws adjacent to the viewfinder screen using a PH0 Phillips screwdriver.

    • Remove the two indicated ribbon cables before separating the two halves of the camera.

    • Using a flat object, pry open the black tabs above the ribbon cable connectors by gently pulling away from the motherboard.

    • An opening pick is recommended, but any equally small and flat object will work.

    • Ribbon cables are fragile, so put as little stress on them as possible.

Hi I had an issue with my camera’s SD card slot and I disassembled to look why it wasn’t reading SD cards and found an issue and I think I fixed it, but when I assembled it it won’t turn on now. Do you have any advice on figuring out what is causing it to not turn on? I checked all flex cables and they seem to be connected. Any help is appreciated!
