TV Products CSV-1 Service Bulletin Sony Service Company - Technical Services A Division of Sony Electronics Inc. Sony Drive, Park Ridge, New Jersey 07656 Model: KV-20TS32/20V50 No. 230 Subject: Afterglow On BA-1 Chassis Date: October 13, 1994 Symptom: (12) After the unit is turned off or unplugged, a small un-focused spot, on the screen, may remain lit. Solution: This phenomena known as Afterglow is normal. It is mostly noticeable when the room lighting is low. Due to the ability of the tube to hold a charge an Afterglow can be seen. This Afterglow duration depends on how fast the tube discharges. This phenomena will not harm the circuits, CRT, or shorten the life of the set. Caution: It is necessary to discharge this tube before handling. Please consult the Service Manual, under the heading Picture Tube Removal, for details on how to discharge this tube. Circuit Upgrade: If a customer can not accept the Afterglow it can be reduced by replacing IC-101 and resetting the ID codes as listed below: Models Applicable Serial Numbers Applicable Serial Numbers Applicable Serial Numbers Afterglow might be Spot Killer circuit added New Micro used to reduce Observed Afterglow KV-20TS32 8,100,001-8,113,000 8,113,001-8,132,000 8,132,001-And beyond KV-20V50 8,100,001-8,107,000 8,107,001-8,109,361 8,109,362-And beyond Note: The spot killer circuit was discontinued, since the new micro circuit does the job that the Spot Killer circuit performed.
