(4)Maintain as angle of (3) and rotate the tab to accord with vertical line of Red and Blue color in the middle of screen.
(5)Open angle of the two tab of 6 pole magnet by isogonic angle and accord with vertical line of Red/Blue and Green.
(6)Maintain as angle of (5) and rotate the tab to accord with horizontal line. In case of twisted horizontal line,repeat adjustment of (3) ~ (5) remembering the movement of Red/Green/Blue color.
(7)Move the DY to best condition of convergence and attach the CPT to a
5.Screen voltage adjustment
(1)Receive the PAL or SECAM(NTSC) signal into RF mode regardless of channel.
(2)If you press the ÒADJÓbutton in LINE SVC
(3)Adjust the screen volume of FBT jack,When width line is seen turn the FBT screen volume at the position of disappearance it.
(4)Press the TV/AV button to exit SVC mode.
6.White balance adjustment
NOTE : When adjusting white balance automatically,connect the adjustment JIG in SVC mode.(When pressing ,MUTE button on remote control, it changes to CPU OFF MODE and screen displays ÒAUTOÓ.)
(1)Receive 100% white pattern.
(2)Adjust LOW Light status(4.5FL) of CUT R,CUT B at CG:60.
(3)Adjust HIGH LIght status(35FL) of WDR R,WDR B at WDR G:450.
(4)Repeat above step (2) and (3) for the best condition each status of High Light and Low Light.

7.Deflection setting Data Adjustment
7.1Adjustment preparation
(1)Tune the TV set to receive an Digital pattern(EU05CH).
(2)Deflection setting data adjustment is operate by SVC communicator.
(3)Enter the deflection adjustment mode by selection SERVICE1 on SERVICE MENU after pressing LINE SVC
(4)Use the CH D ,E key to select adjustment item.
(5)Use the VOL F ,G key to increase/decrease data.
<Note>
(1)When adjusting a deflection, adjust N50Hz of PAL signal first and adjust a deflection at Normal 60Hz(NTSC).
(2)Adjust a deflection as shown below.
PAL 4:3
(3)After finishing deflection adjustment, press the ENTER key to exit in adjustment mode.
* Before adjusting the PIP P(PIP Position), store the deflection data in the EEPROM by using the ÒENTERÓ key.
7.2Adjustment
(1)VL(Vertical Linearity) adjustment:
Adjust the top & bottom size of inner circle to be equal.
(2) VA (Vertical Amplitude) adjustment:
Adjust so that the circle of a digital circle pattern should be located interval of 6~7mm from the effective screen of the CPT.
(3) SC (S correction) adjustment:
Adjust so that all distance between each lattice width of top/center/bottom are to be the same.
*Setting the CPT Default(Initial data) value like that, because it is decide by CPT DY value
