    • Remove the following screws from the motherboard using the JIS #00 screwdriver:

    • Two 3.9mm JIS screws.

    • Three 2.9mm JIS screws

    • Gently pull the motherboard out of the camera.

    I was wondering how did you get to loosen the 3.9mm Phillips screw on the top right.

    lucato -

    Fixed that, the orange marker was a bit off, it was on an alignment pin instead of the actual screw which was just a bit more to the right.

    Flying Dutchman -

    I cannot reach the 3.9mm screw with any tool because it is underneath of the plastic body that holds the zoom +/- buttons. How old you remove that top right motherboard screw?

    Jeff Ramsey -

    I hate to bring up an old question, but did you ever manage to get this screw off with your camera? I am working on mine yet I am about to simply drill through the plastic under the zoom buttons.

    jeremy cohan -

    You have to remove the top part of the camera body to reach the screw. It is also much easier to reconnect flat cables.

    Max -

    Where can I find a replacement board. I cannot find one anywhere!

    Matt Jones -

    Same here, how to remove this top-right orange 3.9mm phillips screw?

    If top has to be removed, how to do that? It’s not visually obvious to me at the moment.

    Also, really where to get the replacement MB?

    Giorgi -

    That last top-right screw is actually impossible to remove - need to take off the top cover. Follow this guide:

This guide gets an upvote.

It's the first camera disassembly guide I've seen so far on ifixit that includes the single most important precaution: the camera has a body cap fitted to avoid dust, dirt or other objects getting into the mirror box. Bravo!

Where can we buy the parts?
