  • Using a Phillips #00 precision screwdriver, remove the last 4mm screw located inside the input ports' compartment.

I've tried this before and I remember this screw not coming off why is this?

Hello Jun. If you are using the correct screwdriver, there may be a few answers to your question:

The camera screw is stuck:

This happened to the team that did this project, just keep working with the screwdriver until it comes loose.

The camera screw lost threads:

If a screw is screwed in incorrectly, it could be permanently lodged in the camera and you will be unable to open it.

The camera screw head is rounded:

If the small pieces of the head (visible) part of the screw are gone with groove marks, the screw is permanently damaged and cannot be removed unless you have special equipment.

Other than these tips, you may need to look elsewhere for more help.

Thank you for the quick reply! Does this have to do with it being the last screw to be taken out? do the screws have to be screwed out in this order? Thank you

Jun Hong -

There is no order for removing the screws. However, we did take note it was the most difficult to remove because of it's placement. It is difficult to get a grip on the camera when attempting to loosen this screw, therefore it is more prone to damage. Keep trying, but don't force the screw out to where the part may become damaged by means listed in the previous comment.

  • Place a plastic opening tool into the gap between the back panel and camera body, from both the top and the bottom of camera. Carefully pry open the camera and separate the back panel.

  • Using tweezers or your fingers, pull the display's black ribbon from the motherboard. This frees the back panel altogether.

  • Using a Phillips #00 precision screwdriver, remove the 3mm screw holding the top panel of the camera in place. Also, remove the screws under hot shoe metal clip, otherwise you can break a piece of sensor frame leading to costly repair.

It's not possible to remove the top panel with just the plastic opening tool. I think there is a screw underneath the hot shoe attaching the top panel to the camera metal chassis. The photos show a broken metal tap from the camera chassis attached to the top panel metal plate. Someone must have used a lot force to break the tab and get the panel off. I stopped trying to take the panel off because I figured out the problem with my camera.

  • The jog dial should fall out easily. If not, use a pair of tweezers to gently poke it though the power board.

Thanks, this was useful. Camera was switching modes randomly. I didn't replace the PCB however, just opened and sprayed a lot of silicon oil into the dial.

Thanks! I fixed my camera. But i think step 10 not necessary.

Perfect ! My Camera was switching modes randomly too. I changed the board from step 9 with a new part found on Ebay. Thank you :-)
