Introduction
The Panasonic DMC-FZ200 camera rear wheel switch has seen multiple reported failures. Most reports have the push action fail to register the requested settings changes while a fewer number of switches have seen the rotating dial fail to register. Either condition can be repaired by replacing the faulty rear wheel switch with a new unit.
I suggest downloading a copy of the DMC-FZ200 Service Manual as a reference. I also recommend printing the pertinent pages and placing any removed screws or parts on the pages where they're identified to help ensure the right parts go back where they came from.
I also suggest reviewing the following document to familiarize yourself with the Zero Insertion Force (ZIF) connectors used for connecting flex ribbon cables to the system components:
