4.3. Adjustment of White Balance
(for Manual adjustment)
■  Color  analyzer(CA100+,  CA210)  should  be  used  in  the 
calibrated ch by CS-1000
■  Operate the zero-calibration of the CA100+ or CA-210, then 
stick sensor to the module when adjusting.
■  For manual adjustment, it is also possible by the following 
sequence.
1)  Select  white  pattern  of  heat-run  by  pressing  “POWER 
ON” key on remote control for adjustment then operate 
heat  run  longer  than  5  minutes.  (If  not  executed  this 
step, the condition for W/B may be different.)
2) Push “Exit” key.
3) Change to the AV mode by remote control.
4) Input external pattern (85% white pattern)
5)  Push  the ADJ  key  two  times  (entering  White  Balance 
mode) → Enter “0413” (Password)
6)  Stick the sensor to the center of the screen and select 
each  items  (Red/Green/Blue  Gain  and  Offset)  using 
▲/▼(CH +/-) key on R/C..
7) Adjust R/ G/ B Gain using ◄/►(VOL +/-) key on R/C.
8)  Adjust three modes all (Cool / Medium / Warm) : Fix the 
one of R/G/B gain and change the others
9)  When  adjustment  is  completed,  Exit  adjustment  mode 
using EXIT key on R/C.
* CASE
First adjust the coordinate far away from the target value(x, y).
1) x, y > target
i) Decrease the R, G. 
2) x, y < target
i) First decrease the B gain, 
ii) Decrease the one of the others.
3) x > target ,  y < target
i) First decrease B, so make y a little more than the target.
ii) Adjust x value by decreasing the R
4) x < target ,  y > target
i) First decrease B, so make x a little more than the target.
ii) Adjust x value by decreasing the G
■  Standard color coordinate and temperature when using the 
CA100+  or  CA210  equipment  (Small  size  inch’s  color 
coordinate is different from others, So use below table)
1)  All  Edge  LED(except  LGD),  lamp  over  26  and  None 
Edge LED(LGD Direct LED 42inch) and LGD Edge LED 
26inch Over
2) 22” TN Edge LED
(Small  size  inch’s  color  coordinate  is  different  from 
others, so use below table)
3) 22” Lamp (CMI & THTF)
(Small  size  inch’s  color  coordinate  is  different  from 
others, So use below table)
4)  W/B table in process of time which must be applied for 
LGD edge LED module
    (Target color coordinate is different by aging time)
CA210 : CH 14, Test signal : Inner pattern (85IRE)
To check the Coordinates of White Balance, you have to 
measure at the below conditions.
Picture Mode : Vivid(User)
Dynamic Contrast : Off , Dynamic Colour : Off
(If you miss the upper condition, the coordinates of W/B 
can be lower than the spec.)
