Subject: Faint Vertical Bars on Screen. Date: June 6, 2000
Symptom:
(1343) Faint vertical bars may be seen on the screen (see illustration below). Typically, the
bars are found about 5" from the left side and/or about 14" from the right side.
Applicable serial numbers: 9000001 ~ 9000753
Solution: If the customer complains of this symptom, make component changes to the CG-
board and the D-board. Also, add a ground wire between ground lug CN5015 on the
D-board and a spare ground lug on the CRT chassis, and add 2 solder bridges as
shown on the following pages.
NOTE: On sets with serial numbers up to and including 9000150 the D-board
must be replaced with a later version. The new D-board still requires the
following procedure to be performed.
