How to fix or replace mode dial.
The mode dial on my GH1 no longer works. I’m stuck in film mode. I disassembled it but stopped as I was getting too deep. I must admit that I used the dial a lot. I use manual lenses and I used the film setting to adjust before I switch to photo mode. This way I don’t over or under expose. The mode switch used to click, now it turns freely but doesn’t change the settings. I suspect it is either broken or came loose. I may try to source another switch but I need to know how to get at it. Any help would be appreciated.
