3-1 Service Instruction

1. General Adjustment :
In general, a color TV can provide ideal visual quality by adjusting the basic settings such as the vertical size, horizontal size,
focus, etc.
Display a black and white picture on the screen to check if the picture is clearly displayed.
If there are some 'spotted' points on the screen when displaying a black and white picture, degauss the screen using the
degauss coil. If the spotted points remain, re-adjust the purity and the convergence. This completes the basic performance
examination.
Notice.
■ These adjustments and the check list are only applied to KS9C chassis-applied models.
■ use 110v for the measurement set. It is recommended using an
insulation transformer when supplying power to the set so as to prevent shock to the set or to yourself.
■ These adjustment specifications have been created on the basis of the domestic KS9C chassis-applied remote
control model. Some of the contents may be changed subject to the sales location and the product specifications.
2. When replacing the Main Board :
