Yashica FX-3: Film Advance Lever Triggers Shutter – Repairable?

Hey everyone,

I have a Yashica FX-3 with a strange issue: when I push the film advance lever, the shutter fires immediately. This makes the camera unusable since I can’t properly advance the film or control when the shutter releases.

Has anyone encountered this problem before? Is this something that can be fixed at home, or would it require professional repair? Any advice would be greatly appreciated!

Thanks in advance!
