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, Warm and Medium
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 and select third
row like (Fig. 5)
-To enter White-balance mode, Enter Password Number “0
0 0 0” and select third row.
* Caution: System control Host should be “DDC” for adjustment.
(6) Adjust W/B DATA, for all CSM, choose ‘COPY ALL’

- Equipment
1) Color analyzer(CA100+, CA210) should be used in the
calibrated ch by CS-1000(PDP : CH10)
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

(VOL +/-) key on R/C.
(6) Adjust three modes of Cool, Medium(Vivid) and Warm as
below figure.
(Fix the one of R/G/B and change the others)
- Push the “VOL + “ key : Cool, Medium, Warm
(Fix the one of R/G/B and change the others)
- Push the “VOL + “ key : Cool, Medium, 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.
