- Adjust by commanding AUTO_COLOR_ADJUST.
2) 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 Remote control.
After enter Service Mode by pushing "ADJ" key,
execute "ADC Adjust" by pushing "
CALIBRATION : COMPONENT".
