5. SET assembly adjustment method 
5.1. Input Area-Option  
5.1.1.  Profile : Must be changed the Area option value
because being different of each Country’s
Language  and signal Condition.  
5.1.2.  Equipment : adjustment remote control. 
5.1.3.  Adjustment method 
- The input methods are same as other chassis.(Use IN-
START Key on the Adjust Remocon.) 
Refer to Job Expression of each main chassis ass’y
(EBTxxxxxxxx) for Option value.   
5.2. Adjustment of White Balance  
•  In case of keeping module is in the circumstance of 0°C, it
should be placed in the circumstance of above 15°C for 2
hours  
•  In case of keeping module is in the circumstance of below -
20°C, it should be placed in the circumstance of above 15°C
for 3 hours. 
- 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
- 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 (85% 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
D
E
(CH +/-) key on R/C.. 
9) Adjust R/ G/ B Gain using 
F
/
G
(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 case of Edge LED module, the color coordinates is
changing by aging, so you have to use the below table.

The Time Table of color coordinates by SET Aging Time   
1) Edge LED Models : LV3700 / LV5500 / LW5700 
2) ALEF & IOP model : LW9500 / LW7700/LZ9700 
• In the SET applied LED module
(LV55/LW57/LW77/LW95/LZ97 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.
