It is a known problem on some related cameras: Yashica FX-D Yashica FX-70 Yashica FX-3 Contax 139 The mirrors are glued in place with a thermoelastic glue. The problem is usually caused by the camera being left in an automobile in a hot climate. The glue becomes plastic and the mirror slides out of place. The glue seems to have a memory so it needs to be re-melted. One solution I have used, and have recommended here before, is to use a hair dryer or other heating tool to re-melt the glue and move the mirror back into place. You need to get it back to the temperature it encountered in the automobile; likely 140-150 degrees F. This is a bit risky and anyone trying this accepts full responsibility for the results, but patience seems to work, and I have not heard about any failures yet.
