5.1. Adjustment Preparation
▪ W/B Equipment condition
CA210: CH14, Test signal: Inner pattern(80IRE)-LED Module
▪  Above 5 minutes H/run in the inner pattern. ("power on" key 
of Adjustment remote control)
* The spec of color temperature and coordinate.
▪  ROW  LED  W/B Table  in  process  of  aging  time  (Only  LGD 
ROW module)
*  Connecting picture of the measuring instrument
(On Automatic control)
Inside  Pattern  is  used  when  W/B  is  controlled.  Connect  to 
auto controller or push Adjustment Remote control POWER 
ON  →  Enter  the  mode  of  White-Balance,  the  pattern  will 
come out.
* Auto-control interface and directions
(1)  Adjust in the place where the influx of light like floodlight 
around is blocked. (Illumination is less than 10 lux).
(2)  Adhere closely the Color analyzer(CA210) to the module 
less than 10 cm distance, keep it with the surface of the 
Module and Color analyzer's prove vertically.(80° ~ 100°).
(3) Aging time
-  After aging start, keep the power on (no suspension of 
power supply) and heat-run over 5 minutes.
-  Using 'no signal' or 'POWER ONLY' or the others, check 
the back light on.

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 Module)
* Manual W/B process using adjust Remote control.
■  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.
■ After enter Service Mode by pushing “ADJ” key,
■  Enter  White  Balance  by  pushing  “►”  key  at  “9.  White 
Balance”.
■  For manual adjustment, it is also possible by the following 
sequence.
(1)  Set  TV  in Adj.  mode  using  “P-ONLY”  key  on  remote 
controller  and  then  operate  heat  run  longer  than  15 
minutes.(If not executed this step, the condition for W/B 
may be different.)
(2) Push “Exit” key.
(3)  Enter White Balance mode by pushing the ADJ key and 
select  “9.  White  Balance”.  When  KEY  (►)  is  pressed, 
206 Gray internal pattern will be displayed. 
(4)  Zero Calibrate the probe of Color Analyzer, then place it 
on the center of LCD module within 10cm of the surface
(5)  Select  each  items  (Red/Green/Blue  Gain)  using 
▲/▼(CH +/-) key on Remote control.
(6) Adjust R/ G/ B Gain using ◄/►(VOL +/-) key on R/C.
