▪ Purpose :  Adjust the color temperature to reduce the deviation 
of the module color temperature.
▪ Principle :  To adjust the white balance without the saturation, 
Fix the one of R/G/B gain to 192 (default data) and 
decrease the others.
▪ Adjustment mode : Three modes – Cool / Medium / Warm
 Required Equipment
▪ Remote controller for adjustment 
▪  Color Analyzer : CA100+ or CA-210 or same product (should 
be used in the calibrated ch by CS-1000)
- LCD TV : CH-9
- PDP TV : CH-10
- White LED TV : CH-14
- RGB LED(MNT) : CH-16
- Auto W/B adjustment instrument(only for Auto adjustment)
5.2.1. Adjustment of White Balance : 
          (For Automatic Adjustment)
Connecting  diagram  of  equipment  for  measuring  (For 
Automatic Adjustment)
1) Set TV in adj. mode using POWER ON key
2)  Zero  calibrate  probe  then  place  it  on  the  center  of  the 
Display
3) Connect Cable(RS-232C)
4) Select mode in adj. Program and begin adj.
5)  When  adj.  is  complete  (OK  Sing),  check  adj.  status  pre 
mode(Warm, Medium, Cool)
6) Remove probe and RS-232C cable to complete adj.
▪  W/B Adj.  must  begin  as  start  command  “wb  00  00”  ,  and 
finish as end command “wb 00 ff”, and Adj. offset if need
  Luminance  min  value  is  150cd  in  the  Cool/Medium/Warm 
mode( For LCD)
5.2.2. 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 15 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 (80% white pattern)
5)  Push the ADJ key => Enter “0000” (Password)
6)  Select “3. W/B ADJUST”
7)  Enter the W/B ADJUST Mode
8)   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..
9)  Adjust R/ G/ B Gain using ◄/►(VOL +/-) key on R/C.
10)  Adjust  three  modes  all  (Cool  /  Medium  /  Warm)  :  Fix  the 
one of R/G/B gain and change the others
11) When adjustment is completed,  Enter “COPY ALL” 
12) 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
Change reason :  When  vivid  mode,  more  detail  than  other 
company set.

■  In the SET applied LED module (LS5700/LM6200/LM6600/
LM7600  Series),  cause  of  the  physical  characteristics  of 
LED  Module,  sets  are  taken  a  120  minutes  by  aging  time 
to  stabilize  a  color  coordinates.  So  White  Balance  Control 
equipments have to get the SET Aging Time from the SET 
and then going to control the W/B by revise color coordinates 
at each time
-  To  check  the  Coordinates  of  White  Balance,  you  have  to 
measure at the below conditions.
  Picture Mode : select Vivid and change  
  Dynamic Contrast : Off , 
  Dynamic Colour : Off, 
  Clear White : Off
   ->Picture Mode change : Vidid -> Vivid(User)
(If you miss the upper condition, the coordinates of W/B can be 
lower than the spec.)
5.3. Intelligent Sensor Inspection Guide 
Step 1. Turn on the TV set.
Step 2. Press “EYE” button on the Adjustment remote controller.
Step  3.  Block  the  Intelligent  Sensor  module  on  the  front  C/A 
about 6 seconds.
When  the  “Sensor  Data”  is  lower  than  20,  you  can  see  the 
“OK” message  -> If it doesn’t show “OK” message, the Sensor 
Module is defected one.
You have to replace that with a good one.
Step 4. After check the “OK” message come out, take out your 
hand from the Sensor module.
-> Check “Sensor Data” value change from “0” to “300” or not. 
      If it doesn’t change the value, the sensor is also defected 
one. You have to replace it.
5.4. LAN Inspection
1) LAN Port connection with PCB
2) Network setting at MENU Mode of TV
3) Setting automatic IP
4) Setting state confirmation
5)  If  automatic  setting  is  finished,  you  confirm  IP  and  MAC 
Address

5.6.2. Method : Auto
1)  Press “Power on” key of service remocon.(Baud rate : 115200 
bps)
2) Connect RS232 Signal Cable to RS-232 Jack
3) Write Serial number by use RS-232.
4) Must check the serial number at Instart menu
5.6.3. Method : Manual
* If the TV set is downloaded By OTA or Service man, Sometimes 
model name or serial number is initialized.
( Not always) It is impossible to download by bar code scan, so 
It need Manual download.
1) Press the ‘instart’ key of ADJ remote controller.
2) Go to the menu ‘6.Model Number D/L’ like below photo.
3) Input the Factory model name or Serial number like photo.
