just recently purchased a Mamiya 7 with 43mm lens. I had it CLA'D and calibrated. The circuit board was replaced. I received it back and installed a fresh battery and a roll of film and the shutter won't fire. I removed the film and tried it again, same thing happened. The shutter curtain is open, I went over everything and read the manual. The battery reads 6.25v on my meter. I tried dry firing with the back door open and it works perfect. Is there something I am doing wrong.
