Function E: WB PARMS SETUP
The function of "WB PARMS SETUP" is to preset a group of data which for the
Function A "WB AUTO ADJUST" Chromatic and Luminance Standard and Tolerance.
First the computer ask for select WB configuration file, then the user can set the WB data:
a) x = x coordinate of colour
b) y = y coordinate of colour
c) Y = luminance
d) X = Acceptable tolerance of x
e) Y = Acceptable tolerance of y
f) Y = Acceptable tolerance of Y
g) Max time = Max time for adjustment
h) Luminance level offer adjust = low Bright luminance
i) Color = Color of NN5198K/NN5199K
J) Tint = Tint of NN5198K/NN5199K
k) S-Bright = S-Bright
l) U-Bright = U-Bright
m) Contrast = Contrast
n) Cut off R =Cut off R
o) Cut off G =Cut off G
p) Cut off B =Cut off B
q) Drive R = Drive R
r) Drive B = Drive B
of NN5198K/NN5199K
Model : UBM
Maximum time = 30 Sec
Luminance level after adjustment: 14
After finishing setup, press «Esc» and confirm to save setup or leave the menu.
Function F: EXIT TO DOS
Just exit the adjustment program and back to dos environment.
B. Colour Purity, Convergence Adjustment and +B Voltage Check
i. Colour Purity Adjustment (See FIG.4)
BEFORE ANY ADJUSTMENTS DESCRIBED BELOW ARE ATTEMPTED, V-HIGH, B+ VOLTAGE AND FOCUSING
ADJUSTMENT MUST BE COMPLETED.
a. Place the TV receiver facing NORTH or SOUTH.
b. Plug in TV receiver and turn it on.
c. Operate the TV receiver over 30 minutes.
d. Fully degauss the TV receiver by using an external degaussing coil.
e. Receive a crosshatch pattern and adjust the static convergence control roughly.
f. Loosen the clamp screw of the deflection yoke and pull the deflection yoke towards you.
g. Enter into ADJUST MENU. Set the values of C-R, C-G, C-B to "00".
h. Adjust the purity magnets until green field is obtained at the center of the screen.
i. Slowly push the deflection yoke toward cone of CRT and set it where a uniform green field is obtained.
j. Tighten the clamp screw of the deflection yoke.
k. After COLOUR PURITY ADJUSTMENT, you must adjust the WHITE BALANCE again.
