prompt "success" for adjustment completion is displayed;
e) Input Component signal (VG-848 Timing:972(1080i)，Pattern:918 100% color bar), move
cursor to item "MODE"，press keys "▲" and "▼" to select item "YPbPr（HD）", then move
cursor to item "AUTO ADC" and press key "OK" to begin adjustment automatically until a
prompt "success" for adjustment completion is displayed.
3.1.4
ADC correction of RGB channel
a) Switch to RGB channel (D-SUB channel);
b) Press key "SOURCE", then press number keys "2、5、8、0" to enter into initial factory menu;
c) Move cursor to item "ADC Calibrate" and press key "OK" to enter into interior factory menu;
d) Input RGB signal (VG-848 Timing:856(1024×768/60 Hz)，Pattern:920 8 step Gray), move
cursor to item "MODE"，press keys "▲" and "▼" to select item "RGB", then move cursor to
item "AUTO ADC" and press key "OK" to begin adjustment automatically until a prompt
"success" for adjustment completion is displayed.
3.2 White balance adjustment
Unless specified by customer, default COOL color temperature is 12000K, chromaticity
coordinates is (272、 278); default Standard color temperature is 9300K, chromaticity coordinates
is(285、 293); default Warm color temperature is 6500K, chromaticity coordinates is (313、 329).
3.3 White balance adjustment processes
The set should be working above 30 minutes before white balance adjustment for it would be in a
stabler state. Use white balance apparatus CA-210 and switch to its BBY channel.(19" for
example)
a)
Switch to HDMI channel；
b)
Press key "SOURCE", then press number keys "2、5、8、0" in turn to enter into initial factory
menu;
c)
Move to item "W/B ADJUST" and press key "OK" to enter into interior factory menu;
d)
Input HDMI signal (VG-848 Timing: 856(1024×768/60 Hz)，Pattern:921 16 step Gray),
move cursor to item "MODE", press keys "▲" and "▼" to select item "HDMI", then move
cursor to item "TEMPERTURE", press keys "▲" and "▼" to select item "COOL"；
e)
Fix item "G GAIN", adjust item "R GAIN、B GAIN" to set chromaticity coordinates of the 13
step is (272、278)；
f)
Fix item "G OFFSET", adjust item "R OFFSET、 B OFFSET" to set chromaticity coordinates of
th
the 4
step is (272、278)；
g)
During adjustment , make sure that color temperature of bright step is (X=272±5,Y=278±15)
and color temperature of dark step is (X=272±8,Y=278±30);
h)
Then move cursor to item "COPY ALL" to copy white balance data to the other channels;
i)
Check if color temperature of STANDARD and WARM meet requirements as below:
STANDARD: allowable error of bright step is (X±10, Y±15), allowable error of dark step is
(X±10,Y±25); WARM: allowable error of bright and dark step are both (X±10,Y±10);
otherwise adjust items "R_GAIN /B_GAIN/R_OFFSET/B_OFFSET" to meet requirements and
then save data;
j)
Check if the white balance of the other channels meet the requirements, if not, adjust the data
and save separately.
k)
Check if the picture of every channel is normal after adjustment;
