12. Deflection Data Adjustment
12-1. Preliminary steps
(1) Deflection Data Adjustment should be performed with the
remote controller for handset.
(2) The TV Set receives signals as followings.

NOTE: If production line doesn’t have the production line
of LG TV, receive available deflection adjustment
pattern (Ex: Cross-hatch + Circle)
(3) Adjustment sequence is based on 3 Mode adjustments
and Initial adjustment is started from a standard adjustment
mode.
1) Sequence : PAL (100Hz)

2) After adjusting PAL (100Hz) press the ENTER key and
then Click “ Deflection”.
Click the MODE key of remote controller and adjust the
50p (50Hz Progressive).
(Remark : A lower column of OSD shows ‘100’ or ’50’ when
mode is ‘100Hz’ or ‘50Hz’ respectively.)
3) In the case of press the ENTER key in the PAL(100Hz),
the data of PAL (50p) and NTSC would be changed at the
same time.
(4) Adjustment Mode entry and remote controller control
method.
1) Enter adjustment mode: Click the “ADJ” Key

12-2. Adjustment
(1) VL (Vertical Linearity)
In line adjustment, not to change default value is basic
Adjust the top & bottom size of inner circle to be equal.
(2) VA (Vertical Amplitude)
Adjust upper and lower part of circle from the effective
screen of the CPT .to be distance of 6~7mm
(3) SC (Vertical S correction)
In line adjustment, not to change default value is basic
Adjust the lattice width of the Top/Center/Bottom to be the
same.
As being decided by DY value of the using CPT, set as
default of using CPT.
(4) VS (Vertical Shift)
Adjust so that the horizontal center line of a digital circle
pattern is in accord with geometric horizontal center of the
CPT.
(5) HS (Horizontal Shift)
Adjust the vertical center line of a digital circle pattern is in
accord with geometric vertical center of the CPT.
(6) EW (East-West Width)
Adjust outer line of the left/right outer lattice to be united
with effective boundary surface of CPT.
- Adjust (1) of [Fig 4] that it is with 1/3 points on external
lattice from PAL adjustment.
- Adjust (2) of [Fig 4] not to be visible for 3 units from NTSC
adjustment.
(7) ET (East-West Trapezium)
Adjust so that vertical line be parallel to vertical boundary
surface of CPT.
(8) EP (East-West Parabola)
Adjust so that middle portion of the outermost left and
right vertical line looks like parallel with vertical lines of
the CPT.
(9) CRNU (Upper Corner Correction).
Adjust so that corner vertical line of upper-left and upper-
right to be straight line after finishing EP adjustment.
(10) CRNL (Lower Corner Correction)
Adjust so that corner vertical line of lower-left and lower-
right to be straight line after finishing EP adjustment
(11) BOW
In line adjustment, not to change default value is basic
(12) ANGLE
In line adjustment, not to change default value is basic
In angle adjustment, adjust until inclination of center
vertical line should be vertical precisely.
