Model:          KWP-65HD1                                                           No.       474
Subject: No Audio On Certain DTV Programs.                                          Date: February 24, 2000


Symptom:
 (C510)                There is no audio heard from certain DTV programs that use audio data rates greater
                       than 384 Kbits/second. All NTSC (analog) program audio is O.K.



Solution:              If the customer complains of this symptom, send the digital receiver/decoder box to
                       the following address so that it can be reprogrammed with new firmware:

                               Sony Service Center
                               128 Westwood Industrial Center
                               390 University Ave.
                               Westwood, Massachusetts 02090

                       Be sure to include a note indicating that the digital receiver/decoder is being sent in
                       for reprogramming according to this service bulletin.

                       Firmware version 2.02 or higher corrects the symptom.

                       Digital receiver/decoder boxes with serial numbers higher than S010700745X
                       already have the firmware that prevents the symptom from occurring. Do not
                       confuse the digital receiver/decoder box serial number with the TV's serial number.
                       The digital receiver/decoder box serial number is printed in small-size characters on
                       the label on its rear panel.
