I dont know if this is a commen problem but my father has a Sony CD changer hooked up to his factory Blupunkt tape player with the seperate CD changer controls. It used to work fine and now all that happens is that the cd changer turns on and you can switch disks but it does not recognize when there is a cd in the slot, and won't play. I was wondering if anyone had any idea of what this might be, weather its the changer, head unit, or the changer control.
