Minolta XG-A The function switch on my xg-a (Self-timer, off, on, b.c.) seems stripped and will not work. Is there an easy way to repair this myself, or do I need to get it to a shop?

If the function switch/selector is very loose on the camera body, it may need to go in for repair. There is a plastic collar that the rewind shaft passes through that holds the function switch in place. It will break from age. Otherwise, you may be able to make repairs yourself. You can remove the rewind knob by holding the fork of the rewind shaft with small pliers, (hold it so the flat sides of the fork meet the pliers jaws) and turning the rewind knob counter-clockwise. The function switch is held to the previously mentioned rewind collar by a small plate. There will be two loose pieces, a spring and detent ball). There is another switch plate under the top cover that the function switch mates to. A pin from the function switch fits into a small hole in the underside plate. That plate will go beyond the working range making the hole impossible to see. You might have to relocate it so the hole is seen in the slot before you put the function plate back on.
