Ass'y
①Separate the cables from the Main Board and CRT Ass'y
①Separate the wires from the FBT of the Main Board and
the CRT Ass'y.
②To separate the thick red wires, pull the wires while pressing
the push-type clip at the connector.
③To separate the thin red wire, insert a pin in the small hold
next to the hole and pull the wire.
: Take care when separating the wires because pulling the
wires by force may damage the socket. In addition, separate the
wires on a flat and clean surface so as to prevent scratching of
the material and the PCB.
Pull the wires while
pressing on the fixing clip.

3. Alignment & Adjustment
3-1 Service Instruction
1. GeneralAdjustment :
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 KS7C chassis-applied models.
■NorthAmerica use 110V, South Central America use 220v 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 KS7C 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 :
Focus adjustment, screen voltage setting and W/B adjustment are all required.
3. When replacing the CRTAss'y : No adjustments required.
4. When replacing the SideAV : No adjustments required.
