5.5.5.2. 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 -> 7. White-
Balance then press the cursor to the right (KEY►).
(When 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) Adj. is performed in COOL, MEDIUM, WARM 3 modes of
color temperature.
** R-fix adjustment
Adjust modes (Cool), Fix the R gain to 210 (default data) and
change the others (G/B Gain ).
- Adjust the R gain more than 210 ( If G gain or B gain is less
than 0 , R gain can adjust more than 210 ) 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, you can
adjust using RF signal in 216 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
- 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.
