* 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

(4) Standard color coordinate and temperature when using the

CA100+ or CA210 equipment

To check the Coordinates of White Balance, you have to
measure at the below conditions.
Picture Mode : User 1
Dynamic Contrast : Off
Dynamic Colour : Off
(If you miss the upper condition, the coordinates of W/B
can be lower than the spec.)

Step 1. Turn on the TV set.
Step 2. Press “EYE” button on the Adjustment remote control.

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.

(1) Test Condition.

Must located another set in a state of DC ON (without
checking set) in closer distance(5M).
-On total assembly step, S/W deal with connection 
(between Set and another Set, other device that be
compatible with Bluetooth)

(2) Need device : same set in closer distance, adjustment

remote control

(3) Method

1) Push  “Power on key” on adjustment remote control.
change  “Bluetooth On” mode
2) Push “EXIT” key
3) Push ”B-TOOTH”(NEW) or “PIP”(OLD) key
4) Check “Searching OK” message
5) Push “Exit” key, finish check.
