(3) Press the “ADJ” key of the factory remote control three
times to enter to “SUB-TINT” adjustment mode.
(4). Change the Sub-Tint data by pressing the VOL¢∏,VOL¢∫
Key until the upper and lower CYAN color becomes same
color.
9. Deflection setting data adjustment
These adjustment will be done by Auto Adjustment
Equipment.
For manual adjustment, it is also possible by the following
procedure.
9-1. Adjustment Preparation
(1) Deflection setting data adjustment can be done only with
remote control.
(2) Press the “INSTART” Key on the factory remote control
continuously to enter to Deflection Adjustment mode.
(3) Press the CHD, EKey to select adjustment item.
(4) Press the VOLF, G Key to change the data.
9-3. Adjustment (21” Super Slim, Ultra S/S Model)
(1) Vertical Position Adjustment
Select SVC02(V-POS) and adjust so that the horizontal
center line coincide with geometric horizontal center of the
CPT.
(2) Vertical Linearity Adjustment.
Select SVC02(V-LIN) and adjust so that the size of the
upper circle is alike with the one of the lower circle at LG
standard pattern signal (PAL : EU05CH, NTSC : 13CH).
(3) Vertical Size Adjustment.
1) NTSC :Select SVC02(VA) and adjust so that the middle
circle of the Digital Pattern (480NC, 13CH) coincide with
the effective screen of CPT.
2) PAL : Select SVC02(VA) and adjust so that the middle
circle of the Digital Pattern (PAL B/G 5CH) has 6~7mm
gaps from the effective screen of CPT.
(4) Horizontal Position Adjustment
Select SVC02(H-POS) and adjust so that the left and right
vertical line are symmetrical as possible.
(5) Horizontal Size Adjustment
Select SVC02(EW WIDTH) and adjust so that the outer line
of the left, right and the remotest grid will correspond to the
effective boundary surface.(The remotest grid, NTSC:
within 2.5 ~ 3.0 column, PAL: within 0 ~ 25%)
(6) Parabola Adjustment
Select SVC02 (EW PARAB) and adjust so that the vertical
line of the remotest grid at the left or right side of the screen
will be parallel to the vertical line of the center of screen
(7) Trapezoidal Adjustment
Select SVC02(EW TRAPE) and adjust so that the width of
the upper part of screen is alike with the one of the lower
part of screen.
(8) EW UPCOR/ LOCOR Adjustment
Select SVC02(EW UPCOR, EW LOCOR) and adjust so

that the vertical line in the four corners become straight
line.
(9) BOW Adjustment
Select SVC02(HP BOW) and adjust so that the vertical line
in the four corners become straight line.
9-2. Adjustment
(1) Horizontal Position Adjustment
Select SVC02 (H-POS) and adjust so that the left and right
vertical line are symmetrical as possible.
(2) Vertical Position Adjustment
Select SVC02 (V-POS) and adjust so that the horizontal
center line coincide with geometric horizontal center of the
CPT.
(3) Vertical Size Adjustment
Select SVC02 (VA) and adjust so that the middle circle of
the Digital Pattern (480NC, 13CH) coincide with the
