I just acquired a Pentax Auto 110 SLR with 2 lenses, auto-wonder, case, and a couple of rolls of film. When I got it, I could not see through the viewfinder, the film advance lever would move about halfway, and it seemed like the shutter was stuck. I just bought a pair of brand new Energizer 357/303 1.55v batteries and put an old roll of half-used 110 film that was in the camera. A solid yellow light shows up in the viewfinder, but nothing happens when I press the shutter button, also, nothing happens when I try to cock the film advance lever. I still cannot see through the viewfinder. Is this a known problem? How can I fix this really neat camera?
