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
F
, VOL
G
key until the upper and lower CYAN color becomes same
color.
9. Deflection setting data adjustment
These adjustment will be done by automatic 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 “IN-START” key on factory remote control continuously
to enter to Deflection Adjustment mode.
3) Press the CH
D
,
E
key to select adjustment item.
4) Press the VOL
F
,
G
key to change the data.
9-2. Adjustment
1) Horizontal Position Adjustment
Select VP1(H-POS) and adjust so that the left and right
vertical line are symmetrical as possible.
2) Vertical Position Adjustment
Select VP2(V-POS) and adjust so that the horizontal center
line coincide with geometric horizontal center of the CPT.
3) Vertical Size Adjustment
Select VP3(V-SIZE) and so that the middle circle of the
Digital Pattern(480NC, 13CH) coincide with the effective
screen of CPT
4) H-SIZE
Adjustment of the H-size is not basically done but if the H-
size is inappropriate, the H-size is adjustable by adjusting
variable resistance(VR403) of the main assy.
-> Adjustment for the received pattern is done 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 %)
5) Trapezoidal
Adjust a trap by adjusting variable resistance(VR402) of the
main A’ssy.
-> Adjustment is done so that the upper horizontal width of
the received screen and the bottom horizontal width will
be same (when the screen is a trapezoid shape, adjust it
to make a right square)
6) PIN AMP.
Adjust the pin AMP by adjusting variable resistance(VR401)
of the main A’ssy.
-> Adjustment is done 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 ( or the remotest
grid of CPT)
