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
- PDP TV : CH-10
- White LED TV : CH-14
- ALEF : CH-18
- 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)
5.2.2.1. Adj. condition and cautionary items
(1) Lighting condition in surrounding area surrounding lighting
should be lower 10 lux. Try to isolate adj. area into dark
surrounding.
(2) Probe location: Color Analyzer (CA-210) probe should be
within 10cm and perpendicular of the module surface (80°~
100°)
(3) Aging time
1) After Aging Start, Keep the Power ON status during 5
Minutes.
2) In case of LCD, Back-light on should be checked using no
signal or Full-white pattern.
5.2.2.2. Equipment

Balance then press the cursor to the right (KEY►). When
KEY(►) is pressed 216 Gray internal pattern will be
displayed.
(4) One of R Gain / G Gain / B Gain should be fixed at 192,
and the rest will be lowered to meet the desired value.
(5) Adj. is performed in COOL, MEDIUM, WARM 3 modes of
color temperature.
▪ If internal pattern is not available, use RF input. In EZ Adj.
menu 6.White Balance, you can select one
of 2 Test-pattern:

than 0 , R gain can adjust more than 210 )
and change the others ( G/B Gain ).
Adjust two modes(Medium / Warm), Fix the one of R/G/B gain
to 192 (default data) and decrease the
others.
▪ If internal pattern is not available, use RF input. In EZ Adj.
menu 7.White Balance, you can select one of
2 Test-pattern: ON, OFF. Default is inner(ON). By selecting
OFF, you can adjust using RF signal in 216
Gray pattern.
5.2.3.2. Medium / Warm Mode

■ In the SET applied LED module (LM9600), 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.
