My father has a Aiwa Z-M2600. (Bought in 1998).
Although the CD player can play CDs, it does not recognise every CD out of the 5 which can be held at any one time on the "Direct Disk Play/Rotary Changer System".
I intend to remove the outer casing and see if perhaps there is a sensor which is most probably coated in dust. If so I will clean it, if not I will have to come up with another plan.
Other suggestions appreciated.
