CONFIDENTIAL CSV-1 Sony Service Company National Technical Services Service Bulletin A Division of Sony Electronics Inc. Park Ridge, New Jersey 07656 TV Products Model: KW-34HD1 No. 450 Subject: A-board And B-board Production Changes: Date: January 5, 2000 Old And New Versions Are Not Compatible. Symptom: (****) The design of the A-board and B-board was changed in early December 1999 to add V-Chip capability for analog and digital programs, and Closed Captioning for digital programs. The model number of the set was not changed. All other boards used in the new version of the set are the same as the boards used in the former version of the set. The digital receiver box (set-back box or "SBB") supplied with the new version set has firmware version 2.20 or higher. The version number can be read out from the service mode in category "DTV", adjustment item "AGCL", data "1". It is O.K. to use a new version SBB with a former version set. The only difference is that now the customer will have Closed Captioning for digital programs which was not available with the former version SBB. All SBB's being supplied from the World Repair Parts Center have version 2.20 firmware or higher.
