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 K16A chassis-applied models.
Only use 230V 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 K16A chassis-applied remote control
model. Some of the contents may be changed subject to the sales location and the product specifications.
