a) Product ID

b) Serial No:  Controlled on production line.
c) Month, Year: Controlled on production line:

ex) Monthly : ‘03’ -> ‘03’ 

Year      : ‘2005’ -> ‘0F’

d) Model Name(Hex): 

e, f) Checksum: Changeable by total EDID data.

Caution : Before White-balance, the AV ADC should be done.

<Notice> 
- Do the white balance adjustment under the 10LUX
- Before white balance, press the ADJ key 2times and do the

reset like Fig.2

- Use the Torino inner pattern (216 gray pattern)  
-To enter White-balance mode, press the ADJ key 2times. 

Caution - System control RS-232 Host should be “PC” for

adjustment.

[Test Equipment]
- Color Analyzer (CA-110)
- CA-210

PC (for communication through RS-232C) -> UART Baud rate
: 115200
Pattern Generator (MSPG-925FA etc. )

[Color Temperature & Color Coordinates Setting]
When adjusting the Color Temperature of LCD, Color
AnalyzerCA-210(Matrix should be corrected through CH9 of
CS-1000) should be used.
Adjust the Color Temperature based below adjustment color
coordinates.
Even if CH9 of CA-210 is corrected with Matrix, there may be
many character of Module and Filter.
Therefore Refer to the below Color Coordinates Target.
But, in case of WCG module, use the CH12 of CA-210. 

* Target Value CA-210 (CH 9)

(R/G/B gain and R/G/B offset Default values are different in

For White Balance, Adjust twice, Cool and Warm

1) Execute CA-210(9CH, 10CH and 12CH) or CA-100 Zero

Calibration. (In case of WCG module,CH12 and PDP,
CH10)

2) Execute the SET Heat Run for 30minutes
3) Use torino inner pattern as below Fig. 3, Supply 216Level

(85 IRE) full screen pattern 

4) Enter the White Balance adjustment mode by pressing the

ADJ key twice(White Balance) on R/C.

5) Stick sensor to center of the screen and select each items

on R/C..

6) Adjust with R/G/B Gain using

7) Adjust it until color coordination becomes as below. 

After All adjustment is completed, Please push “In-stop” key.

* Color Temperature : Cool, Medium, Warm
One of R/G.B Gain should be fixed at 80 and adjust two Gain
Value with decreasing the Default values from 80.
- When R Gain is Fixed at Default value(80)

Adjust G gain and B gain with decreasing Default values
from 80

- When B Gain is Fixed at Default value(80)

Adjust R gain and G gain with decreasing Default values
from 80

- When G Gain is Fixed at Default value(80)

Adjust R gain and B gain with decreasing Default values
from 80

R/G/B Gain and R/G/B Offset Default Value
Red Gain : 80,  Green Gain :  80,  Blue Gain : 80
Red Offset : 80,  Green Offset :  80,  Blue Offset : 7D
