If production line doesn't the production line of LG
TV,receive available deflection adjustment pattern.
10-2. Adjustment
VL (Vertical Linearity)
Adjust the top & bottom size of inner circle to be equal.
Adjust Linearity of the upper/ lower part at the U-VL or L-VL.
VA (Vertical Amplitude)
Adjust upper and lower part of circle from the effective screen of
the CPT.to be distance of 6~7mm.
SC (Vertical S Correction)
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 the using CPT.
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.
HS (Horizontal Shift)
Adjust so that the vertical center line of a digital circle pattern is in
accord with geometric vertical center of the CPT.
EW (East-West Horizontal Width)
Adjust outer line of the left/ right outer lattice to be united with
effective boundary surface of CPT.
* Receive Cross-hatch pattern to adjust horizontal Pin-Cushion.
A-BOW(AFC Bow)
In line adjustment, not to change default value is basic.
A-ANG(AFC Angle)
In angle adjustment, adjust until inclination of left and right screen
should be precise.
EPP(East-West Pin Phase)
Adjust so that horizontal width of the uppermost part and horizontal
width of the lowermost part of received screen are to be the same.
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.
UC(Upper Corner Correction)
Adjust so that corner vertical line of upper-left and upper-right to be
straight line after finishing EP adjustment.
Actual screen size
50Hz
LC(Lower Corner Correction)
Adjust so that corner vertical line of lower-left and lower-right to be
straight line after finishing EP adjustment.
V-SCR(V-Scroll)
Only adjust when V SHIFT is impossible.
* After adjusting as above, finish the Pin Cushion by re-
adjustment of EW, EPP, A-ANG, A-BOW, UC, LC.
* After adjusting, move to "Store This Mode". And then change to
"Store All Mode" and save by using press "OK" key.
