5.3. White Balance Adjustment
(1) Overview
• W/B adj. Objective & How-it-works
- Objective: To reduce each Panel’s W/B deviation
- How-it-works: When R/G/B gain in the OSD is at 192, it
means the panel is at its Full Dynamic
Range. In order to prevent saturation of
Full Dynamic range and data, one of
R/G/B is fixed at 192, and the other two is
lowered to find the desired value.   
- Adj. condition : normal temperature
1) Surrounding Temperature: 25±5ºC
2) Warm-up time: About 5 Min
3) Surrounding Humidity: 20% ~ 80%
(2) Equipment
1) Color Analyzer: CA-210 (NCG: CH 9 / WCG: CH12)
2) Adj. Computer(During auto adj., RS-232C protocol is
needed)
3) Adjust Remocon
4) Video Signal Generator MSPG-925F 720p/216-Gray
(Model:217, Pattern:78)
-> Only when internal pattern is not available
• Color Analyzer Matrix should be calibrated using CS-1000
(3) Equipment connection MAP
(4) Adj. Command (Protocol)
1) RS-232C Command used during auto-adj.
Ex) wb 00 00   ->  Begin white balance auto-adj.
wb 00 10   ->  Gain adj.
ja 00 ff   ->  Adj. data
jb 00 c0
...
...
wb 00 1f   -> Gain adj. complete
*(wb 00 20(start), wb 00 2f(end)) -> Off-set adj.
wb 00 ff   -> End white balance auto adj.
2) Adjustment Map
Applied Model : LA02B Chassis ALL MODELS 
(5) Auto adj. method
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 
(6) Manual adj. method
1) Set TV in Adj. mode using POWER ON
2) Zero Calibrate the probe of Color Analyzer, then place
it on the center of LCD module within 10cm of the
surface..
3) Press ADJ key -> EZ adjust using adj. R/C > 6. White-
Balance then press the cursor to the right (KEY
G
).
(When KEY(
G
) 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: ON, OFF. Default is inner(ON). By
selecting OFF, you can adjust using RF signal in 216
Gray pattern.

* 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
- LCD: Color Analyzer (CA-210) probe should be
within 10cm and perpendicular of the module
surface (80°~ 100°)
3) Aging time
- After Aging Start, Keep the Power ON status during 5
Minutes.
- In case of LCD, Back-light on should be checked
using no signal or Full-white pattern.
(7) Reference (White Balance Adj. coordinate and color
temperature)
1) W/B Equipment condition
CA210 CCFL/EEFL -> CH9, Test signal, Inner
pattern(80IRE)
LED(AUO) -> CH14, Test signal, Inner pattern(80IRE)
2) Above 5 minutes H/run in the inner pattern. (“Powre on”
key of adjust remote control)
• Edge LED W/B Table in process of time(Only LGD
module)
CA210 : CH14, Test signal : Inner pattern(80IRE)
5.4. 
HDCP (High-Bandwidth Digital
Contents Protection) SETTING 
- HDCP setting is not necessary in This Chassis.  
5.5 MAC Address Download 
For downloading the MAC address which be allotted on
each LAN Card. 
5.5.1 Adjustment Method  
1)  Connecting the TV set and the PC which has MAC
Address Writing program through  The RS232C cable.  
2)  Editing the macaddress.txt 
(Inserting start MAC address at top low. )
(Inserting start MAC address at bottom low. )
Launch MAC Address Writing program and set just like
below picture.(1) 
3) Click the LOAD button for reading the MAC address.(2) 
(SAVE : Saving the current MAC Address      
CLEAR : Initializing the space which insert MAC
Address. )
4) Click  the  “ MAC Address” button to write current MAC
Address.(3) 
5)  In case of being downloaded normally, you can see the
(4) message with “ OK” in the window.  
6) In case of being downloaded normally, MAC address
increased one by one  automatically. So the next set,
just click the “ MAC Address‚  ” button after  connecting
the port. 
(Whenever be finished, the program saves the MAC
Address in “ macaddress.txt” file automatically.)
