Introduction
By following these ten steps one can effectively replace the Nikon COOLPIX P7700 camera's internal reflective mirror.
What you need
-
-
Turn camera to the left side and remove the two 4.3 mm black side screws using the Phillips #00 screwdriver.
-
Remove the side panel.
-
-
-
Open the touch screen, and remove the three 4.3 mm black screws inside using the Phillips #00 screwdriver.
If you fix the p7800, the right down screw is different, its not a countersink, its flush.

-
Begin separating the camera into two parts.
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.
Step 4: I had to remove the blank screw as well..

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.
And how can you calibrate, adjust?
