Sounds like Paul ron is probably right. It seems to make no difference if the pin is pushed in or not. I paid 60 for it, not terrible, but it was described as fully functioning, and I know I could still take pictures, but I do not want to have to guess when I'm at the next frame. I am not that handy Paul but my brother is a mechanical engineer and this stuff comes very natural to him, so I would be interested in seeing those pictures, I am 90% sure that the internal mechanism must be the problem and I sure would like to get this thing fixed up!
