(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 rubber-chock for fixed DY.
5. Screen voltage adjustment
(1) Receive the PAL or SECAM(NTSC) signal into RF mode
regardless of channel.
(2) If you press the “ADJ”button in LINE SVC mode(IN-START
button),the LINE SVC mode changes to screen adjustment
mode.
(3) Turn the Screen Volume of FBT to change luminance of
White signal center as shown below.
(4) Press the EXIT 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 IN-
START,MUTE button on remote control for adjustment
orderly,it changes to SVC mode and screen displays
“CUT OFF”.)
(1) Receive 100% white pattern.
(2) Adjust LOW LIght status(4.5FL) of CUT R,CUT B at
CG:70.
(3) Adjust HIGH LIght status(35FL) of WDR R,WDR B at
WDR G:380.
(4) Repeat above step (2) and (3) for the best condition each
status of High Light and Low Light.
<CAUTION> W/B Program “Twbeng_v2.0”
- W/B adjustment after Cutoff
: Instart -> adj. -> mute(cutoff)-> tv/av(wb)
Release key is EXIT key
- W/B adjustment
: Instart -> mute(cpuoff) ->
Release key is TV/AV key
7.Deflection setting Data Adjustment
7.1 Adjustment 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 mode by selection SERVICE1 key on
SERVICE MENU after enter the adjustment mode by
pressing LINE SVC MODE(IN-START KEY).
(4) Enter the deflection mode by pressing ADJUST key.
(5) Use the CH
D
,
E
key to select adjustment item.
(6) 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 -> NTSC 4:3
(3) After finishing deflection adjustment,press the EXIT key to
exit in adjustment mode.
(4) Wide Models
After adjusting 16:9(50Hz), Readjust 14:9(50Hz) ->
ZOOM(50Hz) -> 4:3(50Hz) -> 16:9(60Hz) -> 14:9(60Hz) ->
ZOOM(60Hz) -> 4:3(60Hz).
7.2 Adjustment
(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 (Vertical S correction) adjustment:
Adjust so that all distance between each lattice width of
top/center/bottom are to be the same.
