3. Alignment & Adjustment3-1 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 K63A chassis-applied models.■ Only 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 K63A 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 System Board :Since the software is loaded to the flash memory of the system board, check the version of the software after replacing the board.To check the version of the software, select Menu-Settings-Function Help-Settings and press the "Information Display" key on the remote control. The software information will then be displayed below the OSD menu.The notation of the software information : For example, T_NATRNUS0_1004 refers to

"NATURAL MODEL USA. ver1004".Since the settings including the Channel information, Deflection, etc. are saved to the nvRAM, reconfigure these settings when replacing the System Board.

3. When replacing the Deflection Board :Tilt adjustment, focus adjustment, screen voltage setting and W/B adjustment are all required.

4. When replacing the Power Board : No adjustments required.

5. When replacing the CRT Ass'y : No adjustments required.

6. When replacing the front panel master power switch : No adjustments required.
