Date: October 26, 1995 Symptom: (57) The audio skips when the outer tracks of the disc are being played. This symptom may be caused by grease and/or oil being deposited on the disc surface from the CD mechanism. The problem may be found in a small percentage of the above mentioned models. If it is determined that the customer’s complaint is caused by the grease and/or oil problem mentioned above, the customer’s XA-10B magazine will be exchanged as detailed below, and therefore the customer must provide his/her original XA-10B magazine before the the repaired changer can be returned to him/her. Solution: 1- Thoroughly clean the grease and/or oil from the lock assy. exactly as shown in the drawing. First, remove any excess grease or oil by wiping the lock assy. with a dry cotton swab. Then, perform a final cleaning by wiping with a cotton swab moistened with alcohol. 2- Clean the rubber roller thoroughly with a cotton swab moistened with alcohol. 3- Move one side of the white plastic roller away from the metal plate, then thoroughly clean the roller (including the outer edge of the roller) with a cotton swab. Next, slip a piece of kraft paper (the paper that grocery bags are made of) between the ends of the roller and the chassis and rotating the roller by hand. Perform a final cleaning by wiping the roller with a cotton swab moistened with alcohol. Repeat this procedure for the opposite side of the roller. 4- Clean the white portions of the ARM(R) ASSY. 5- Remove the washer from the WORM WHEEL (C), then add a COVER (GEAR) and secure it with a +P 2x4 screw.

However, small amounts of mechanism lubricating oil may have previously been transferred to your magazines and some of your discs. It is especially important that you examine your discs, and clean them where necessary, prior to loading them into the new magazine being provided to you along with your CD changer. Failure to clean the discs may result in oil being transferred from the discs to the magazine and CD changer, which might cause skipping problems. If you have additional XA-10B disc magazines which had been loaded into this CD changer prior to it being serviced they may also contain small amounts of oil. We recommend that you send any such XA-10B magazines to Sony at the address shown below for examination. Sony will return your XA-10B disc magazines to you in usable condition, or at our option replace them with new magazines, free of charge. A copy of your CD changer in-warranty repair invoice must be included with the XA­10B disc magazine(s) for free examination and cleaning/ replacement.

Date: May 11, 1995 Symptom: (65) The display on the controller shows “RESET”. When the magazine is ejected, disc # 10 remains loaded in the mechanism. This problem may be caused by disc # 10 hitting the front edge of the magazine top cover as it is being returned to the magazine. This problem is more likely to occur when the changer is installed vertically rather than horizontally. When this problem occurs, models prior to the CDX-45/65 will have disc # 10 loaded and chucked. CDX-45/65 and later models will have disc # 10 loaded but it will not be chucked. If the disc is chucked in the CDX-45/65 and later models, the problem is caused by something other than the magazine (for example, mis-operation of the magazine detect switch). Solution: Replace the customer’s magazine with a new one which has a beveled front edge as shown below.

Date: March 25, 1996 Symptom: (51) There is no audio when the CDX-91 is connected to the MDX-U1 or XDP-U50D via the analog connection (the audio is normal when the digital connection is used). Solution: This problem may occur if IC31 on the CDX-91 SERVO board is the newest type (CXP84332-014Q). If the above mentioned symptom occurs, and if IC31 is the newest type, replace it with the former type (CXP84332-008Q). Also, if the suffix of the silkscreened part number on the MD board is “-13” a trace on the MD board must be cut as shown in the illustration. Finally, if the XDP-U50D is being used, make sure that the procedure described in Car Stereo Service Bulletin # 377 has also been performed.
