Got slide projector out, put loaded carousel on and plugged into wall, turned on and adjusted focus. Everything seemed to be working fine, until I used the remote reverse button and something jammed up. I pressed the little gray button to eject the lowered slide, now can't get slides to advance or reverse, button doesn't work to eject slides, light doesn't come through front lens. I suspect some connector or springs have broken inside. Can I get replacement parts?
