  • It is okay to remove the orange ribbon. This will be easily put back into place when re-assembling.

a. Remove plastic plate between main body & LCD screen (where the thumb is in the pic).

b. Remove one screw (the only one) found behind the plastic plate.

This is the most scary moment as I did not know how to remove the orange flat cable. I would not come off and I broke off a little plastic. Somehow it came off accidentally as I moved the backcover. The cable was later re- inserted with care, from the right towards the left via a very thin slit.

"It is okay to remove the orange ribbon. This will be easily put back into place when re-assembling." Easily put back? Yeah, right (not!). It is actually anything but easy. I managed doing it after several attempts, but it was more by luck than skill. The ribbon is tiny, the contacts even more so and the slot into which the ribbon must be reinserted - I cannot even see it properly. A pair of small tweezers is a must for this step.

  • Remove the back casing.

It would be better to lift the little white adhesive tape so that the backcover could be worked on.

There is a further screw hidden under the black cover on the left hand side of the camera (visible in step 1).

Without removing this silver screw, it is not possible to take the camera apart.

There should be an explanation about how to properly remove the ribbon cable. One has to flick up a dark part attached to the ribbon cable socket (opposite to where the ribbon cable enters). Putting the cable back is not “easy”, it is rather fiddly. One needs to put down the dark part again, after inserting the cable.

The three screws for the silver backplate that presses the sensor against the spacers and lens need to be tighten just the right amount. One cannot just fully tighten them. These three screws determine the distance of the sensor to the lens and also its alignment to the lens. One essentially needs to perform a sensor calibration when putting the camera together again.

Finally, the part replaced in this guide is not a “reflective mirror”. It is probably a low pass filter, potentially an IR filter or both.
