5.2.2.1. 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 (90+/-
2.5°)
3) Aging time
A. After Aging Start, Keep the Power ON status during 5
Minutes.
B. In case of LCD, Back-light on should be checked using
no signal or Full-white pattern.
5.2.2.2. Equipment
1) Color Analyzer: CA-210 (NCG: CH 9 / WCG: CH12 / LED:
CH14)
2) Adj. Computer (During auto adj., RS-232C protocol is
needed)
3) Adjust Remocon
4) Video Signal Generator MSPG-925F 720p/216-Gray
(Model: 217, Pattern: 78)
5.2.2.3. Adjustment
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 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.
▪ 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 216 Gray pattern.
** 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.
