Had the same problem. My Volvo dealer checked the fuse . New replacement fuse blow out which told me the problem was within the disc player itself. I had to make the decision - have the old unit repaired or purchase a new unit from Volvo . I went to a nationally known home/car audio store and they sell trunk mounted ALPINE/6 disc replacement units for Volvos. I had to purchase an electrical adopter unit which plugs into the rear of the radio unit so the replacement unit works off the radio unit the same as the factory installed CD changer. Most satisfied with the results.
