<p>Hi All.</p>
<p>I bought a mamiya 645 yesterday. All was working fine. When I got it home, I couldn't get it to take a shot. It kept flashing no Fb. So i replaced the battery in the film back incase that was it. It wasn't. Also, when I took the back off, the shutter stayed in place, even after I pressed the small metal catch near the base.<br>
I then managed to not put the dark slide in properly when I put the film back on, and when I took it out, it won't go back in, as the camera wont fire. Have I just got a dudd here? Any ideas on what to try?<br>
Thanks,</p>
