Replying to Yashica Rangefinder Repair...

Anybody have any experience repairing rangefinders?

I have a Yashica Electro 35CC and overall it is in great shape, however I can't focus via the rangefinder (there's no overlapped image/frame). My guess is that either a reflective coating has been damaged (perhaps due to improper cleaning by a previous owner) or a mirror within the rangefinder isn't moving as it should be (more likely).

Before I take it apart, I'm just curious if anyone has any history with a similar repair.

I've found the repair manual for the camera and am prepared to take it apart...but figured I would see if any of the film nerds on here had any other ideas.

Thanks!
