2) Confirmation
- We confirm whether “0xAA (RGB)” address of
EEPROM “0xA2” is “0xAA” or not.
- If “0xAA (RGB)” address of EEPROM “0xA2” isn’t
“0xAA”, we adjust once more
- We can confirm the ADC values from “0xA4~0XA9
(RGB)” addresses in a page “0xA2”
* Manual ADC process using Service Remocon. After
enter Service Mode by pushing “ADJ” key,
execute “ADC Adjust” by pushing “
execute “ADC Adjust” by pushing “
G
” key at “ADC

4. Total Assembly line process
4.1. Adjustment Preparation
(1) W/B Equipment condition
CA210: CH 9, Test signal: Inner pattern (85IRE)
(2) Above 5 minutes H/run in the inner pattern. (“power on”
key of adjust remote control)
(3) 15 Pin D-Sub Jack is connected to the AUTO W/B
EQUIPMENT.
(4) Adjust Process will start by execute I2C Command (Inner
pattern (0xF3, 0xFF).
(5) 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)

(There is a difference between picture image and set)
* After done all adjustments, Press “In-start” button and
compare Tool option and Area option value with its BOM, if it
is correctly same then unplug the AC cable.
If it is not same, then correct it same with BOM and unplug
AC cable.
For correct it to the model’s module from factory JIG model.

* Don’t push The “IN STOP KEY” after completing the function
inspection.
4.2. DPM operation confirmation
(Only Apply for MNT Model)
Check if Power LED Color and Power Consumption operate
as standard.
- Set Input to RGB and connect D-sub cable to set
- Measurement Condition: (100-240V@ 50/60Hz)
- Confirm DPM operation at the state of screen without Signal
as standard.
- Set Input to RGB and connect D-sub cable to set
- Measurement Condition: (100-240V@ 50/60Hz)
- Confirm DPM operation at the state of screen without Signal
4.3. DDC EDID Write (RGB 128Byte)
- Connect D-sub signal cable to D-sub Jack.
- Write EDID Data to EEPROM(24C02) by using DDC2B
- Write EDID Data to EEPROM(24C02) by using DDC2B
protocol.
- Check whether written EDID data is correct or not.
4.4. DDC EDID Write (HDMI 256Byte)
In case of 2008 year new model for Australia and Taiwan
which is developed with Mstar scaler, Manufacture gave no
use for downlad of EDID for HDMI 1/2/3/4 because HDMI
EDID data is in the Application Program.
