I have had this unit since 2003 with absolutely no trouble at all. Over the last two days I went to play a CD and it refuses to play! First it says "No Disc." It also comes up "CO2 and NO PLAY" I have no children, the sterio is kept in a locked cabinet in a safe and dry condition, where it has been since 2003. It is hardly ever used! I've tried it since with different CD but the same thing happens every time. Does anybody know how to fix this/where and cost, please? Would be grateful for any help...Much thanks
