9-4. Adjustment of White Balance for
Manual Adjustment
Adjustment mode: Two modes of Medium(Vivid) and Warm
(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 :
CH9, 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.
(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)
(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
(Red/Green/Blue Gain and Offset) using
on R/C..
(5) Adjust R/ G/B Gain using
(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

[ Refer to the below case to know what value is fixed.
[CASE]
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.
- 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
1) First decrease B, so make y a little more than the target.
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
(7) When adjustment is completed, Exit adjustment mode
using EXIT key on R/C.
