Total Assembly Line Process; Function Check; Confirm Color Coordinate Of Rgb/Av2/Component; Confirm Auto Adjustment Operation - LG FLATRON M198WA Service Manual

<Adjustment pattern (COMPONENT)>
- Adjust by commanding AUTO_COLOR_ADJUST
(0xF1) 0x00 0x02 instruction.
2) Confirmation
- We confirm whether "0x8D,0x8E" address of
EEPROM "0xB4" is "0xAA" or not.
- If "0x8D,0x8E" address of EEPROM "0xB4" isn't
"0xAA", we adjust once more.
- We can confirm the ADC values from "0x00~0x05"
addresses in a page "0xB4".

3.3. Function Check

(1) Check display and sound
- Check Input and Signal items. ( cf. work instructions)
