4.2. White Balance Adjustment
4.2.1. Overview
▪ W/B adj. Objective & How-it-works
(1) Objective: To reduce each Panel's W/B deviation
(2)  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. 
(3) Adjustment condition : normal temperature
1) Surrounding Temperature : 25 °C ± 5 °C
2) Surrounding Humidity : 20 % ~ 80 %
4.2.2. Equipment
(1) Color Analyzer: CA-210 (LED Module : CH 14)
(2)  Adjustment Computer(During auto adj., RS-232C protocol 
is needed)
(3) Adjustment Remote control
(4)  Video Signal Generator MSPG-925F 720p/216-Gray
(Model: 217, Pattern: 49)
→ Only when internal pattern is not available
▪ Color Analyzer Matrix should be calibrated using CS-100.
4.2.3. Equipment connection MAP
4.2.4. Adj. Command (Protocol)
<Command Format>
- LEN: Number of Data Byte to be sent
- CMD: Command
- VAL: FOS Data value
- CS: Checksum of sent data
- A: Acknowledge
Ex) [Send: JA_00_DD] / [Ack: A_00_okDDX]
▪ RS-232C Command used during auto-adjustment.
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. completed
    *(wb 00 20(Start), wb 00 2f(end)) → Off-set adj.
 
wb 00 ff   → End white balance auto-adj.
▪ Adj. Map
4.2.5. Adj. method
(1) Auto adj. method
1)  Set TV in adj. mode using P-ONLY key(or POWER ON 
key).
2)  Zero  calibrate  probe  then  place  it  on  the  center  of  the 
Display.
3) Connect Cable.(RS-232C to USB)
4) Select mode in adj. Program and begin adj.
5)  When adj. is complete (OK Sign), 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.
(2) Manual adjustment. method
1) Set TV in Adj. mode using P-Only key.
2)  Zero Calibrate the probe of Color Analyzer, then place it 
on the center of LCD module within 10 cm of the surface.
3)  Press ADJ key → EZ adjust using adj. R/C → 7. White-
Balance then press the cursor to the right(key ►).
(When right key(►) is pressed 204 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)  Adjustment  is  performed  in  COOL,  MEDIUM,  WARM  3 
modes of color temperature.
-   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
