This is from memory as its a while since ive used one but there is a metal rocker switch or something under the shutter. Over time this bit of metal gets bent out of shape and the shutter gets soft and unresponsive. If you disassemble the shell (even a chimp like me has managed it) and bend that bit of metal back into shape the shutter button is back in the game and back to its hair trigger self.
Yes, this is very easy to do. I did it to an XA2 some weeks ago.
