Holger, look at Step 7. The 2nd flex cable from the left at the top of the camera—be sure that cable is seated well. I just had my camera apart and the screen was not lighting so I reset a couple of cables and that was the one that brought the screen back. I did a complete tear down following these instructions and put it back together. The lens came out and the lens message came back on. I’m wondering if this might have something to do with the motor. I was thinking that the wheel/gear that is attached to the motor drive should be secured on the spindle. Mine was not. It did manage to drive the lens out once. I’m not sure what kind of motor that is and how it works but I’m thinking the next time I take it apart I might just epoxy that gear onto the end of the spindle (unless someone here tells me not to because it is supposed to be that way). Thanks.
