- 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.
