3.1.2.3 Component Gain/Offset Adjustment
· Convert to Component in Input-source
· Signal equipment displays
Impress Resolution 1080i
MODEL: 223 in Pattern Generator(1080i Mode)
PATTERN: 65 in Pattern Generator(MSPG-925 SERISE)
Adjustment pattern (COMPONENT )
· Press the ADJ KEY and then select “2.ADC CALIBRATION
External” by using / (CH +/-) and press ENTER( ).
3.2.1.4 Confirmation
· We confirm whether “0xB3 (480i)/0xBC (1080i)” address of
EEPROM “0xA2” is “0xAA” or not.
· If “0xB3 (480i)/0xBC(1080i)” address of EEPROM “0xA2” isn’t
“0xAA”, we adjust once more
· We can confirm the ADC values from “0xAD~0XB2
(480i)/0XB6~BB (1080i)” addresses in a page “0xA2”
* Manual ADC process using Service Remocon. After enter
Service Mode by pushing “ADJ” key, execute “ADC Adjust” by
pushing “ ” key at “ADC CALIBRATION :COMPONENT”.

3.2 Function Check
3.2.1 Check display and sound
· Check Input and Signal items. (cf. work instructions)
1. TV
2. AV (SCART1/SCART2/CVBS/S-Video)
3. COMPONENT (1080i)
4. RGB (PC : 1920 x 1080 @ 60hz)
5. DVI (PC : 1920 x 1080 @ 60hz)
6. HDMI
7. PC Audio In
* Display and Sound check is executed by Remote controller.
4. Total Assembly line process
4.1 Adjustment Preparation
· W/B Equipment condition
CA210: CH 13, Test signal: Inner pattern (85IRE)
· Above 5 minutes H/run in the inner pattern. ("power on" key of
adjust remote control)
· 15 Pin D-Sub Jack is connected to the AUTO W/B
EQUIPMENT.
· Adjust Process will start by execute I2C Command (Inner
pattern (0xF3, 0xFF).
· Adjust Process will finish by execute I2C Command (Inner
pattern (Inner pattern (0xF3,0x00)).
** Caution **
Color Temperature: COOL, Medium, Warm
One of R Gain/G Gain/ B Gain should be kept on 0xC0, and
adjust other two lower than C0.
(when R/G/B Gain are all C0, it is the FULL Dynamic Range of
Module)
* W/B condition
- Surrounding Temperature : 20 % ~ 80 %
- Surrounding Temperature : 25±5 °C
- warm-up Time : Under 5 Min
* Manual W/B process using adjusts Remote control.
- After enter Service Mode by pushing "ADJ" key,
- Enter White Pattern off of service mode, and change off -> on.
- Enter "W/B ADJUST" by pushing " " key at "3. W/B ADJUST".
