                                    Sony Service Company - Technical Services
                                    A Division of Sony Electronics Inc.
                                    Sony Drive, Park Ridge, New Jersey 07656


Model:      MDS-501                                                         No.    417
Subject: Track name does not appear                                         Date: November 30, 1994
            Applicable Serial no. 504,899 and lower


Symptom:
  (**)          When selecting the last track by quickly rotating the Jog dial, the name of the last
                track does not appear and "No Name" is shown in the display.



Solution:       Replace the System controller (on the display board), IC301, M38197MA-071-FP with
                the improved version M38197MA-076-FP. In addition you must remove the small
                board located between the Digital board and the Mechanism. Remove both the board
                and its lead wires. If attached, remove the jumper wires from the Display board and
                restore the PCB patterns that have been cut (See diagram). Failure to restore the
                patterns will result in faulty clock and date operation. Note that on some sets there
                are no patterns cut, instead two jumper wires are missing on the Display board (one
                jumper is located near S321 and the other near R314). In this case attach the missing
                jumper wires.
