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.

(1) Color Analyzer : CA-210 (NCG: CH 9 / WCG: CH12 /LED

Module:CH14)

(2) Adj. Computer (During auto adj., RS-232C protocol is

needed)

(3) Adj. R/C
(4) Video Signal Generator MSPG-925F 720p/216Gray

(Model:217, Pattern:78)
--> Only when internal pattern is not available

[ 

Color Analyzer Matrix should be calibrated using CS-1000

(2) 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.

(3) Adj. Map

- Applied model: [32LG70-UA] /[42LG70-UA] / [47LG70-

UA] / [52LG70-UA]/ [47LG90-UA] 

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 Sign), check adj. status per

mode (Warm, Medium, Cool)

6) Remove probe and RS-232C cable to complete adj.

O

Adj. must begin w/ command “wb 00 00”, and end w/ ”wb

00 ff” and adj. offset if needed.

Dynamic contrast : off
Dynamic color : off
OPC : Off
Energy saving mode : Off

1) Set TV Picture Mode to Standard and in Advanced

Control, set Dynamic Contrast and Color ‘Off’.

2) Set TV in adj. mode using POWER On Key
3) Press ADJ key —> EZ adjust using adj. R/C
4) Using CH + / - KEY, select 10.TEST PATTERN then

press Enter to place in HEAT RUN mode and wait for
30 minutes.

4) Zero calibrate the probe of Color Analyzer, then place it

on the center of LCD module within 10 cm of the
surface.

5) Press ADJ key —> 7. White-Balance then press the

cursor to the right (KEY 

G

)

(When 

G

is pressed Full White internal pattern will be

displayed)

6) One of R Gain / G Gain / B Gain should be fixed at 192,

and the rest will be lowered to meet the desired value.

7) Adj. is performed in COOL, MEDIUM, WARM 3 modes

of color temperature

O

If internal pattern is not available, use HDMI input.  In EZ

Adj. menu 7.White Balance, you can select one of 3
options: None, Inner, HDMI.  Default is inner.  By
selecting HDMI, you can adjust using HDMI signal.

O

Adj. condition and cautionary items

1) Lighting condition in surrounding area Surrounding

lighting should be lower than 10 lux.  Try to isolate
adj. area into dark surrounding.

2) Probe location

- PDP: Color Analyzer (CA-100, CA-100+, CA210)

probe should be firmly attached to the Module

- LCD: Color Analyzer (CA-210) probe should be

within 10cm and perpendicular of the module
surface (80°~ 100°)

- In case of LCD, B/L on should be checked using no

signal or Full white Pattern
