4. Adjustment
4.1. Overview
- Use factory automation equipment and adjust automatic
movement.
- But, do via passivity adjust in error occurrence.
4.2. Adjustment order
( refer to the Adjustment standard and adjustment command
table)
4.2.1. Board Assembly Line
■ Connect input signal to 15pin D-sub.
■ Ready for adjustment: check whether adjustment command
works normally or not and the operating state of each mode.
■ Check the display state of gray color when 256 gray scale
pattern is embodied.
■ Read by EEPROM Read Command to check whether initial
value is correct or not.
4.2.2. Total Assembly Line
■ Input analog signal. (1920x1080@60Hz)
■ Write HDCP Key to EEPROM(24C16) by using DDC2AB
protocol & HDCP Adjusting Jig equipment [ Address 0xAC
80, 298bytes ]
■ If error is occurred, write and check again.
■ Ready : Warm-up in 5 minutes in the state with
signal(depends on line condition)
■ Connect input signal to D-sub.
■ Default value before adjustment : Contrast "70" , Brightness
4.2.3. Adjustment of Horizontal/Verticality screen
position, Clock and Phase at each Mode.
■ There is no special factory mode adjustment.
Writing initial value of EEPROM in Board Assembly line is
adjusting Preset Mode and Reset mode. (EEPROM is
initialized when AC Power is ON first.)
■ If the change of FOS data is needed after M.P, it is possible
by writing Mode Data with EEPROM write command or
modifying the Mode Data in MICOM itself.
(Caution) Must keep power-on more than 3 seconds after AC
Power-on first time.
4.2.4. Color coordinates adjustment and Luminance
adjustment.
4.2.4.1. Color coordinates adjustment
■ Monitor Contrast / Brightness
- Contrast : 70
- Brightness : 100(Max)
- Energy saving : off
■ CA-110: channel : 8 / CA-210: channel 14
■ Signal Generator :
At cut-off and drive -> 16 step pattern for ADC
- Output Voltage : 700 mVp-p
- Output Mode :
Mode 12(1920x1080+ 60Hz )mode Setting.

4.2.4.2.Adjustment : Board Assembly Line
- 32MB24 model use internal ADC, no need connect D-SUB
cable Internal ADC steps as below
- On AC power on with Aging mode, checking the ADC values
and then decide to do or not,
• Read ADC OFFSET and GAIN flags from 0xA6 0xFD, 0xFE
on NVRAM
• If those values are not 0xAA on Aging mode, must do
internal ADC calibration.
• If the result of internal ADC calibration is OK, save the ADC
result and make the OFFSET and GAIN flags to 0xAA and
make the Internal_ADC flag to INTERNAL.
• Display the result of ADC on Aging Mode OSD and Service
OSD
- If don't use internal ADC, please follow below step
■ Input 16 step pattern for ADC (Mode12, pattern 11).
(Video level : 700 mVp-p)
■ Adjust by commanding AUTO_COLOR_ADJUST
■ Confirm "Success" message in Screen or Check the data of
0XFD, 0XFE address of EEPROM(0XA6) is 0xAA after
waiting 5 seconds
■ If there is "FAULT" message or the data of 0XFD, 0XFE
address of EEPROM(0xA6) is not 0xAA, do adjust again
■ If all Adjustment is completed, the values of 6500K, User
Color and 9300K are saved automatically.
4.2.4.3. Confirm at Total Assembly Line: adjustment
■ Check the data of 0XFD, 0XFE address of EEPROM(0xA6)
is 0xAA.
■ If the data of 0XFD, 0XFE address of EEPROM(0xA6) is not
0xAA, do adjust again by 3.2.4.2.
4.2.4.4. Confirm PRESET 6500K Color coordinates and Adjust
PRESET 9300K Color coordinates .
* Set as Aging mode ON, by commanding AGING_ON/OFF
command code.
* Select Module that is being used in present production by
commanding MODULE SELECT.
* Send SYSTEM RESET command to set Module data.
* Input Full White Pattern (Video level : 700 mVp-p)
EN33S /SW Model are Non TCO model,no need W/B
4.2.4.5. Confirm User color coordinates .
* Confirm Whether User color is saved same as 6500K.
* After confirming Color coordinates, Must return to 6500K
* Confirm whether user color is 50. If the value of user
color(R/G/B) is 30, do adjust again by
LGE Internal Use Only
