I have a aiwa cd changer, dual cassette deck, and tuner model cfd-9888 (or something). The CD changer doesn't work. The drawer works fine, and it seems like the cds load ok too, but when looking for the cd info, the changer will come up with nothing and go to the next disk. Then it happens again until through all three cds, and the screen says there are no cds. I tried cleaning the lens with a cleaner (the cd kind with brushes on it) and nothing. I read the owner's manual which said to reset it. I did, and it worked fine once, then stopped working again. I tried again, still can't get it to work again. How do I fix this thing?
