5.1.2 Adjust method
5.1.3.1 ADC 480i/1080p Comp1, RGB
(1) Check connected condition of Comp1/RGB cable to the equipment
(2) Give a 480i Mode, Horizontal 100% Color Bar Pattern to Comp1. (MSPG-925FA ->Model: 209, Pattern: 65)
(3) Change input mode as Component1 and picture mode as “Standard”
(4) Press the In-start Key on the ADJ remote after at least 1 min of signal reception. Then, select 7.External ADC.
And Press OK or Right Button for going to sub menu.
(5) Press OK in Comp 480i menu
(6) Give a 1080p Mode, Horizontal 100% Color Bar Pattern to Comp1. (MSPG-925FA Model: 225, Pattern: 65)
(7) Press OK in Comp 1080p menu
(8) Perform (6) and (7) in RGB-PC
(9) If ADC Comp is successful, “ADC Component Success” is displayed.
If ADC calibration is failure, “ADC Component Fail” is displayed.
(10) If ADC calibration is failure, after rechecking ADC pattern or condition, retry calibration
(11) If ADC RGB calibration is successful, “ADC RGB Success” is displayed.
If ADC calibration is failure, “ADC RGB Fail” is displayed.
(12) If ADC calibration is failure, after recheck ADC pattern or condition, retry calibration
5.2. Manual White balance Adjustment
5.2.1. 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 (80°~ 100°)
(3) Aging time
1) After Aging Start, Keep the Power ON status during 5 Minutes.
2) In case of LCD, Back-light on should be checked using no signal or Full-white pattern.
5.2.2. 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)
5.2.3. 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
G
).
When KEY(
G
) 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.
