(1) Purpose: to reduce the difference in color temperature

among modules

(2) Principal: A module is in full dynamic range when RGB

Gain on OSD is 192. To adjust the white balance without
causing full dynamic range and full data, fix one of RGB
Gains at 192 and control the other two by reducing them
from 192.

(1) Color Analyzer : CA-210 (NCG : CH 9 / WCG : CH12)
(2) Automatic Computer (with automatic adjustment necessity

and the RS-232C communication being possible)

(3) Remote control for adjustment
(4) Video Signal Generator MSPG-925F 720p, 216Gray

(Model : 217, Pattern 78)=> Applied only when the inner
pattern cannot be used

*Use the Color Analyzer with the matrix calibrated by the CS-

1000

(3) Adjustment Map

(Automatic Adjustment)

1) The adjustment condition should be set by the Power On

key.

2) Perform the zero calibration of the Color Analyzer and

place the probe close to the display center.

3) Connect the communication cable (RS-232C).
4) Select the desired model of the adjustment program and

perform the adjustment.

5) After the adjustment is ended (check the OK sign), check

the adjustment condition for each mode of the set.
(Warm, Medium, Cool)

6) Disconnect the probe and the communication cable to end

the adjustment.

* The adjustment should be started with "wb 00 00" and

ended with "wb 00 ff", and the offset should be adjusted
when necessary.

1) The adjustment condition should be set by the Power On

key.

2) Press the ADJ of the R/C to enter into 'EZ-ADJUST'.
3) Select '10.TEST PATTERN' with the CH +/- key and press

the Enter key for 30 minutes or longer to perform the heat
run.

4) Perform the zero calibration of the Color Analyzer and fix

the sensor with the 10cm or less distance at the center of
the LCD module surface when adjusting.

5) Press the ADJ of the R/C to select '7.White-Balance' of the

Ez-Adjust and press the right arrow key(

G

) to enter into the

adjustment mode. (As soon as you press '

G

', the screen is

entered into the full white inner pattern.)

6) Fix one of the R/G/B gains to 192 and decrease the

remaining two gains to adjust not to exceed 192.

7) The adjustment is done at three white balances of Cool,

Medium and Warm.

(1) Brightness: Full white 216 Gray 
(2) Standard color coordinate and white balance when using

the CS-1000

(3) Standard color coordinate and white balance when using

the CA-210 (CH 9)

• Set write size to 64 bytes 
• Set delay time to 250ms 
• Connect D-sub Signal Cable to D-Sub Jack
• Input HDCP key with HDCP-key- in-program
• HDCP Key value is stored on EEPROM(AT24C512) which is

80~A1 addresses o 0xA0~0xA2 page 

• AC off/ on and on HDCP button of MSPG925 and confirm

whether picture is displayed or not of using MSPG925 

• HDCP Key value is different among the sets.

model only, which selects the rating related country.

2) Applied models: LA84D Chassis applied None USA

Model(Canada, Mexico)

1) Press the In-Start key of the R/C and press the red oval

OP1(PIP CH-) key to enter into the Factory Option menu.

2) Select 1.USA, 2.CANADA or 3.MEXICO from the country

select according to the destination. At this time, use the
volume +/- key to adjust 

- After completing the final test, in order to set the set to the

shipping condition, press the In-Stop key of the R/C to make
sure that the set is turned off.

(1) Preparing for the automatic test on the GND & resisting

pressure 

- Make sure that the power cord is completely inserted into

the set. (When it is disconnected or loosened, test after
inserting it)

(2) Perform the automatic test on the GND & resisting pressure

1) The set with power cord, the cord and the A/V

completely inserted into the tuner is loaded on the pallet
and entered into the automatic test process.

2) Connect the D-terminal AV JACK tester
3) Turn on the automatic (GWS103-4)
4) Perform the GND TEST
5) If it is not good, the buzzer is operated to notify the test

result to the operator.

6) If it is OK, it is automatically switched to the resisting

pressure test. (Disconnect the cord and the A/V from the
AV JACK BOX)

6) Perform the resisting pressure test
7) If it is not good, the buzzer is operated to notify the test

result to the operator.

8) If it is OK, the GOOD LAMP is turned and the stopper is

moves down, and it moves to the next process.

(1) TEST voltage

- GND:1.5KV/min at 100mA
- SIGNAL:3KV/min at 100mA

(2) TEST time:1 second
(3) TEST POINT

- GND test = between Power cord GND and Signal cable

metal GND

- Resisting pressure test = between Power cord GND and

Live & Neutral

(4) LEAKAGE CURRENT: Set to 0.5mArms 

The USB download is for the quick service response via the
S/W upgrade and for applying the S/W upgrade necessary for
the board adjustment

1) After turning on the set, make sure that the display screen

is turned on.

2) When the USB Memory Stick with the upgrade file applied

is inserted into the USB jack on the main board, the
following screen (example) is displayed after several
