6.1.5. Adjustment method
6.1.5.1 Auto adj. method
(1) Set TV in adj. mode using POWER ONLY (P-ONLY) 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 completed (OK Sing), check adj. status of pre
mode (Cool, Medium, Warm)
(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
6.1.5.2. Manual adj. 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 10cm of the surface..
(3) Press ADJ key -> EZ adjust using adj. R/C -> 6. White-
Balance then press the cursor to the right (KEY►).
(When KEY(►) is pressed 204 Gray(80IRE) 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) Adj. is performed in COOL, MEDIUM, WARM 3 modes of
color temperature.
▪ If internal pattern is not available, use RF input. In EZ Adj.
menu 6.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 204 Gray pattern.
▪ Adj. 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 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.
