As far as the shutter not firing it will fire successfully with the film back removed and it also fired successfully before I dropped the back so I assumed that was the issue. I shot about 4 rolls on it last week and even got some developed. Can cracks in the film back prevent it from working properly? It seems like this camera has numerous ways to prevent the shutter from firing.

Hello, I just recently acquired a Mamiya 645 Super from a buyer on eBay. This is my first medium format camera so being as excited as I was I shot endlessly this past week. Everything was working fine with a few exceptions — shutter not firing every so often, power drive not functioning occasionally. On the last day of shooting I dropped the film back while trying to change the film and chipped the dark slide holder. The next day I tried to shoot a new roll of film and the shutter was completely unresponsive. I removed the film back and the shutter would work fine but I couldn't get the shutter to fire while the film back was on. On top of that now I have more problems: — broken mirror stop — AE Prism (worked at first) flashes OVER constantly and won't give exposure readings. What could cause these problems? I've tried everything and I'd rather not invest in another body for this camera considering I just bought this kit. I just want to fix these issues so I can get back to shooting. Help!
