Hello, my multi cd player was working a few weeks ago. It is no longer recognized when I hit the mode button.. it goes from radio to tape and no longer stops at the CD option!! I ejected the 6 CD magazine and inspected the CDS and then placed back in. The CDs get slid to the right one at a time.. so mechanically it appears to work. I just can't seem to get it recognized by the system. Any clues? Thanks.
