4.2.5. Adj. method
(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.
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.
▪ 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.

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.
4.2.6. Reference (White balance Adj. coordinate and
color temperature)
▪ Luminance : 216 Gray
▪ Standard color coordinate and temperature using CS-1000
(over 26 inch)
▪ Standard color coordinate and temperature using CA-210(CH 18)
4.2.7. ALELF & EDGE LED White balance table
- EDGE LED module change color coordinate because of
aging time.
- Apply under the color coordinate table, for compensated
aging time.
