7.3. Adjustment of White Balance for
Manual Adjustment
• Color analyzer(CA110, CA210) should be used in the calibrated
ch by CS-1000(LCD : CH9)
• Operate the zero-calibration of the CA-100+ or CA-210, then
stick sensor to the module when adjusting.
• For manual adjustment, it is also possible by the following
sequence.
1) Push the ADJ key two times (Entering White Blalance
mode)
2) Stick sensor to center of the screen and select each items
(Red/Green/Blue Gain and Offset) using
/
(CH + / -)
key on R/C.
3) Adjust R/G/B Gain using
/
(VOL + / -) key on R/C.
(Fix the one of R/G/B and change the others).
4) Adjust all modes(Cool, Mediun, Warm): Fix the one of
R/G/B gain and change the others.
5) When adjustment is completed, Exit adjustment mode
using EXIT key on R/C.
[CASE]
First adjust the coordinate much away from the target
value(x, y).
1. x, y > target
a) Decrease the R, G.
2. x, y < target
a) First decrease the B gain,
b) Decrease the one of the others.
- In case of decreasing the x, decreasing the R: fix G
- In case of decreasing the y , decreasing the G: fix R
3. x > target , y < target
a) First decrease B, so make y a little more than the
target.
b) Adjust x value by decreasing the R
4. x < target , y > target
a) First decrease B, so make x a little more than the
target.
b) Adjust x value by decreasing the G
** Caution **
Color Temperature: COOL, Medium, Warm
One of R Gain/G Gain/ B Gain should be kept on 0xC0, and
adjust other two lower than C0.
(when R/G/B Gain are all C0, it is the FULL Dynamic Range of
of Module)
* W/B condition
- Surrounding Temperature : 20 % ~ 80 %
- Surrounding Temperature : 25±5 °C
8. Function Check
8.1 Check display and sound
• Check Input and Signal items (cf. work instructions)
1) TV
2) AV (SCART1/ SCART2/ CVBS/ S-Video)
3) COMPONENT (1080i)
4) RGB ( PC: 1920 x 1080 @ 60Hz)
5) DVI ( PC: 1920 x 1080 @ 60Hz)
6) HDMI
7) PC Audio In
* Display and Sound check is executed by Remote controller
9. Preset CH write condition
1) AC on time on only one after assembled automatically
2) CH recover on SVC OSD manually
