Hi all,

I picked up a used Mamiya 645 Super with the AE Prism N Light Meter. I shot a roll of film with it and the whole thing came out blank, except for one shot that had the faintest ghost of an image on it. I went back to the camera and found that the light meter doesn't seem to be working right, it keeps blinking "over" and giving me bad readings when double checked against my Sekonic light meter. I did replace the battery when I first got it with an alkaline battery and thought maybe that was the problem, but I just got some silver-oxide batteries (which are what's recommended) and I'm still having the same problem. I've cleaned all of the contacts, double checked to make sure the shutter was firing properly, and that the shutter wouldn't fire with the dark slide in place... nothing.

Any suggestions?
