9. Adjustment of White Balance
9-1. Purpose and Principle for Adjustment
of the Color Temperature
(1) Purpose: Adjust the color temperature to reduce the
deviation of the module color temperature.
(2) Principle : To adjust the white balance without the
saturation, Fix the one of R/G/B gain to C0 and decrease
the others.
the others.
(3) Adjustment mode: Two modes of Cool and Warm
(Cool data is automatically calibrated by the Medium data)
9-2. Required Equipment
(1) Remote controller for adjustment
(2) Color Analyzer : CA-100+ or CA-210 or same product
(2) Color Analyzer : CA-100+ or CA-210 or same product
- PLASMA TV(ch : 10)
(3) Auto W/B adjustment instrument(only for Auto adjustment)
- Do the white balance adjustment under the 10LUX
[
Notice: When using the Color Analyzer with PDP,
recommend the CA-100 more than CA-210.
If CA-100 can not available, it is also good to use the CA-210.
If CA-100 can not available, it is also good to use the CA-210.
(4) PC (for communication through RGB)
(5) Pattern Generator (MSPG-925FA etc.)
(5) Pattern Generator (MSPG-925FA etc.)
-Before white balance, press the ADJ key 2times and do
the reset like Fig. 4
-To enter White-balance mode, press the ADJ key 2times.
[
Caution: System control Host should be “DDC” for adjustment.

Measuring
(For Automatic Adjustment)
(1) Enter the adjustment mode of the white balance
- Enter the white balance adjustment mode at the same time
heat-run mode when pushing the power on by power only
key
key
- Maintain the white balance adjustment mode with same
condition of Heat-run
- Maintain after AC off/on in status of Heat-run pattern display
(2) Release the white balance adjustment mode
- Release the adjust mode after AC off/on or std-by off/on in
status of finishing the Hear-run mode
- Release the Adjust mode when receiving the aging off
command(F3 00 00) from adjustment equipment)
(3) Enter the adjust mode of white balance
- Enter the white balance adjustment mode with aging
command(F3, 00, FF)
O
Color Temperature & Color Coordinates Setting
- When adjusting the Color Temperature, Color Analyzer CA-
210(Matrix should be corrected through CH10 of CS-1000)
should be used. When CA-210 have used, it don’t need to fit
the CH10.
should be used. When CA-210 have used, it don’t need to fit
the CH10.
- Adjust the Color Temperature based below adjustment color
coordinates.

Manual Adjustment
Adjustment mode: Two modes of Medium(Vivid) and Warm
(Cool data is automatically calibrated by the Medium data)
(Cool data is automatically calibrated by the Medium data)
- Equipment : 1) Color analyzer(CA100+, CA210) should be
used in the calibrated ch by CS-1000(.(LCD :

2) Adjustment remocon
- For manual adjustment, it is also possible by the following
sequence.
Operate the zero-calibration of the CA-100+ or CA-210, then
stick sensor to the module when adjusting.
Operate the zero-calibration of the CA-100+ or CA-210, then
stick sensor to the module when adjusting.
(1) Select white pattern of heat-run by pressing “POWER ON”
key on remote control for adjustment then operate heat run
longer than 15 minutes. (recommend)
(If not executed this step, the condition for W/B will be
different)
longer than 15 minutes. (recommend)
(If not executed this step, the condition for W/B will be
different)
(2) Changing to the AV mode by remote control.(Push front-
AV)
(3) Input external pattern(85% white pattern).
(4) Stick sensor to center of the screen and select each items

(6) Adjust two modes of Medium(Vivid) and Warm as below
figure.
(Fix the one of R/G/B and change the others)
1) Default : Medium(Vivid)
2) Push the “VOL +” key twice : Warm
(Fix the one of R/G/B and change the others)
1) Default : Medium(Vivid)
2) Push the “VOL +” key twice : Warm
[
Refer to the below case to know what value is fixed.
[CASE]
First adjust the coordinate much away from the target value(x, y).
First adjust the coordinate much away from the target value(x, y).
1. x, y > target
1) Decrease the R, G.
2. x, y < target
1) First decrease the B gain,
2) Decrease the one of the others.
2) 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
- In case of decreasing the y , decreasing the G : fix R
3. x > target , y < target
1) First decrease B, so make y a little more than the target.
2) Adjust x value by decreasing the R
2) Adjust x value by decreasing the R
4. x < target , y > target
1) First decrease B, so make x a little more than the target.
2) Adjust x value by decreasing the G
2) Adjust x value by decreasing the G
(7) When adjustment is completed, Exit adjustment mode
using EXIT key on R/C.
