(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  ‘full  white  pattern’  or  the  others, 
check the back light on.

* 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.
(7) Adjust three modes all (Cool / Medium / Warm) 
- For All model w/o LS345
Fix the one of R/G/B gain and change the others
- For G-FIX model
Cool Mode
1)  Fix the one of R/G/B gain to 192 (default data) and 
decrease the others. (If G gain is adjusted over 172 
and R and B gain less than 192 , Adjust is O.K.) 
2)  If G gain is less than 172, Increase G gain by up to 
172,  and  then  increase  R  gain  and  G  gain  same 
amount of increasing G gain. 
3)  If R gain or B gain is over 255, readjust G gain less 
than 172, Conform to R gain is 255 or B gain is 255
Medium / Warm Mode - Fix the one of R/G/B gain to 
192 (default data) and decrease the others.
(8)  When  adjustment  is  completed,  exit  adjustment  mode 
using EXIT key on Remote control.
* CASE Cool 
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.
*  After You  finish  all  adjustments,  Press  “In-start”  button 
and compare Tool option and Area option value with its 
BOM, if it is correctly same then unplug the AC cable.
If  it  is  not  same,  then  correct  it  same  with  BOM  and 
unplug AC cable.
For  correct  it  to  the  model’s  module  from  factory  JIG 
model.
*  Push  the  “IN  STOP"  key  after  completing  the  function 
inspection.
5.2. DDC EDID Write (HDMI 256Byte)
■ Connect HDMI Signal Cable to HDMI Jack.
■  Write  EDID  DATA  to  EEPROM(24C02)  by  using  DDC2B 
protocol.
■ Check whether written EDID data is correct or not.
*  For Service main Assembly, EDID have to be downloaded.
5.3. EDID DATA
1) All Data : HEXA Value
2) Changeable Data :
    *: Serial No : Controlled / Data:01
    **: Month : Controlled / Data:00
    ***: Year : Controlled
    ****: Check sum

■ After enter Service Mode by pushing “ADJ” key,
■ Enter EDID D/L mode.
■ Enter “START” by pushing “OK” key.
