Maybe you've worked on these cameras before, and if so my advice isn't very helpful. I view my first time going into any camera model as most likely a dissection and autopsy, not surgery where the patient lives.
Very true! I've gone so far as removing the base plate and trying to discern what parts have which function which is nearly impossible just by looking at it. Without looking too deeply, service manuals are extremely detailed requiring lots of decoding. It would be nice if there was a tutorial out there that illustrates basic procedures (with pictures!) to repairing these what seem to be common problems. However, there may be no easy solution to those problems, therefore we have to go to Eric!

Thanks, Allan
