This guide should be for beginners, Mr. Symeon Leriou, and you will not only write "Mobo", but also motherboard or Mainboard or Hauptplatine (deutsch)

But I agree with you that it is not complete.

The motherboard is soldered to the on / off board (power supply for the batteries).

Soldering again is almost impossible ...

I haven't seen you unplug the ribbon cable and replace the slide play, you stopped in the middle of the repair, what's the point?

And how can you calibrate, adjust?

But the ribbon cable goes into the camera ... that's only half the repair ... what's the point?
