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.
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) 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.
** G-fix adjustment
Adjust modes (Cool), Fix the G gain to 172 (default data)
and change the others (G/B Gain).
Adjust two modes(Medium / Warm), Fix the one of R/G/B
gain to 192 (default data) and decrease the others.
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,

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°)
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.
