(1) Serial number D/L is using of scan equipment.

(2)  Setting  of  scan  equipment  operated  by  Manufacturing 

Technology Group.

(3)  Serial number D/L must be conformed when it is produced 

in production line, because serial number D/L is mandatory 

by D-book 4.0.

* Manual Download (Model Name and Serial Number)

If the TV set is downloaded by OTA or service man, sometimes 

model name or serial number is initialized.(Not always)

It  is  impossible  to  download  by  bar  code  scan,  so  It  need

deviation of the module color temperature.

Principle :  To adjust the white balance without the saturation, 

Fix  the  G  gain  to  172  (default  data)  and  change 

the others ( R/B Gain ).

Adjustment mode : mode - Cool

▪ Case : Medium / Warm Mode

Purpose :  Adjust  the  color  temperature  to  reduce  the 

deviation of the module color temperature.

Principle :  To adjust the white balance without the saturation,

and decrease the others.

Adjustment mode : Two modes - Medium/Warm

▪ Adj. condition : normal temperature

1) Surrounding Temperature: 25±5 °C

2) Warm-up time: About 5 Min

3) Surrounding Humidity: 20% ~ 80%

(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/204-Gray

(Model: 217, Pattern: 49)

-> Only when internal pattern is not available

▪ Color Analyzer Matrix should be calibrated using CS-100.

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

(1) 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 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 POWER ON 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 216 Gray internal pattern 

will be displayed)

4)  Adjust modes (Cool) Fix the G gain to 172 (default data) 

and change the others (R/B Gain).

Adjust  two  modes  (  Medium  /  Warm)  Fix  the  one  of 

R/G/B  gain  to  192  (default  data)  and  decrease  the 

others.

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 OFF, 

you can adjust using RF signal in 216 Gray pattern.

* CASE Cool

First adjust the coordinate far away from the target value(x, y).

1) x, y > target

2) x, y < target

3) x > target , y < target

4) x < target , y > target

-  Every 4 case have to fit y value by adjusting B Gain and 

then fit x value by adjusting R-Gain 

-  In this case, increasing/decreasing of B Gain and R Gain 

can be adjusted.

How to adjust

1. Fix G gain to 172

     Adjust  R  Gain  and  B  Gain(In  Case  of  Mostly  Blue  Gain 

Saturation)

2. When B Gain > 255, Release Fixed G Gain and Readjust

* CASE Medium / Warm

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)  The one value is bigger than the target then the other 

one should be not much more bigger than target.

iii) In case that we take x off, we also take R (G-gain fix)

In other case that we take y off, we also take G(R-gain fix)

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.

▪ Adjustment 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

:  Color Analyzer(CA-210) probe should be within 10 cm 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.

▪ Luminance : 216 Gray

▪  Standard  color  coordinate  and  temperature  using  CS-1000 

(over 26 inch)

▪ Standard color coordinate and temperature using CA-210(CH 14)

-  EDGE  LED  module  change  color  coordinate  because  of 

aging time.

-  Apply  under  the  color  coordinate  table,  for  compensated 

aging time.
