5) Completed Tool option
3.1. ADC Process 
(1) PC input ADC 
1) Auto RGB Gain/Offset Adjustment
- Convert to PC in Input-source
- Signal equipment displays
Output Voltage : 700 mVp-p
Impress Resolution XGA (1024 x 768 @ 60Hz)
Model : 60    in Pattern Generator
Pattern : 65   in Pattern Generator (MSPG-925,
MSPG-1025 Series)
- Adjust by commanding AUTO_COLOR_ADJUST.
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 Remote control.
After enter Service Mode by pushing “ADJ” key,
execute “ADC Adjust” by pushing “
G
” key at “ADC
CALIBRATION : RGB-PC”.
(2) COMPONENT input ADC 
1) Component Gain/Offset Adjustment
- Convert to Component in Input-source
- Signal equipment displays
<MSPG-925 Series>
MODEL : 209   in Pattern Generator (480i Mode)
Pattern : 65   in Pattern Generator
MODEL : 223   in Pattern Generator (1080i Mode)
Pattern : 65   in Pattern Generator
<MSPG-1025 Series>
Model : 321   in Pattern Generator (480i Mode)
Pattern: 65   in Pattern Generator
Model : 327   in Pattern Generator (1080i Mode)
Pattern: 65   in Pattern Generator
- 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 “
G
” key at “ADC
CALIBRATION : COMPONENT”.

3.2. Function Check
(1) Check display and sound 
- Check Input and Signal items. (cf. work instructions) 
1) TV
2) AV (SCART1/SCART2/S-VHS/CVBS)
3) COMPONENT (480i)
4) RGB (PC : 1024 x 768 @ 60hz)
5) HDMI 1,2
6) PC Audio In
7) RJP
8) LED Clock (check with Real time clock)
9) Alarm Clock
10) Ext Speaker (1W/MONO)
11) Ext 5V/1A or 12V/1A (is different as to BOM option)
* Display and Sound check is executed by remote control.
* RJP Check process
1) Set the power supply switch as shown in the below picture.
2) Turn only the #5 switch on (Up position)
3) Use the RJ-45 cable to connect the TV and JIG.
4) Enter the IN-START mode, and select “RJP Pin Check”.
5) The check result is displayed after 1~2 seconds.
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)
* Manual W/B process using adjusts Remote control. 
After enter Service Mode by pushing “ADJ” key, enter White
Pattern off of service mode, and change off -> on.
Enter “W/B ADJUST” by pushing “
G
” key at “3.W/B ADJUST”. 
* 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.
