Hi guys! I've got a small problem with my Rollei 35S (Singapore), perhaps you can help me with it. Everything else seems to be in perfect working order but the frame counter won't move. I just can't get it to frame number one on the counter. I have examined the mechanism and looks alright (nothing broken) but it doesn't "catch". Has anyone here had the same problem? Is it easily solved or does it require professional repair?. Thanks a lot.
