My 6 CD Autochanger (S3 Bose/Concert system) won't read any CDs. it was working fine and seemed to just stop reading CDs at all one day (there probably was a period where it had the problem intermittently as well. I've tried a few original un-scratched CDs in all the slots and it just says 'ERR1' on the display every time and then moves on to the next disc with the same result. Assuming its just a dirty lens, can I use a normal CD lens cleaner in the autochanger (any recommendations?) or is it time for a new autochanger?
