USB DOWNLOAD

1.  Put the USB Stick to the USB socket 
2.  Automatically detecting update file in USB Stick

- If your downloaded program version in USB Stick is

Low, it didn’t work. But your downloaded version is High,
USB data is automatically detecting

3.  Show the message "Copying files from memory"

4.  Updating is staring.

5.  Updating Completed, The TV will restart automatically.
6.  If your TV is turned on, check your updated version and

Tool option. (explain the Tool option, next stage)

* If downloading version is more high than your TV have, TV

can lost all channel data. In this case, you have to channel
recover. if all channel data is cleared, you didn’t have a
DTV/ATV test on production line.

O  

After downloading, have to adjust TOOL OPTION again.

1. Push "IN-START" key in service remote controller 
2. Select "Tool Option 1" and Push "OK" button
3. Punch in the number. (Each model has their number.)
4. Completed selecting Tool option

3.1 ADC Process 
3.1.1 PC input ADC 

3.1.1.1 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 SERISE) 

Adjustment pattern (PC ) 

- Adjust by commanding AUTO_COLOR_ADJUST.

3.1.1.2 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 "

" key at "ADC

CALIBRATION: RGB-PC".  

3.2.1 COMPONENT input ADC  

3.2.1.1 Component Gain/Offset Adjustment
- Convert to Component in Input-source
- Signal equipment displays

Impress Resolution 480i

MODEL: 209   in Pattern Generator(480i Mode)
PATTERN : 65  in Pattern Generator( MSPG-925 SERISE) 

Impress Resolution 1080i
MODEL: 223   in Pattern Generator(1080i Mode)
PATTERN: 65  in Pattern Generator( MSPG-925 SERISE) 

Adjustment pattern (COMPONENT )

- Adjust by commanding AUTO_COLOR_ADJUST.

3.2.1.2 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 Remocon. After enter
Service Mode by pushing "ADJ" key,
execute "ADC Adjust" by pushing "

" key at "ADC

CALIBRATION :COMPONENT".

3.2 Function Check 

3.2.1 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
6. PC Audio In 

* Display and Sound check is executed by Remote controller.

4.1 Adjustment Preparation  

- W/B Equipment condition

CA210: CH 9, Test signal: Inner pattern (85IRE)

- Above 5 minutes H/run in the inner pattern. ("power on" key

of adjust remote control) 

- 15 Pin D-Sub Jack is connected to the AUTO W/B

EQUIPMENT.

- Adjust Process will start by execute I2C Command (Inner

pattern (0xF3, 0xFF).

- 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 "

" 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.

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

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

protocol.

- Check whether written EDID data is correct or not.

4.4. DDC EDID Write (HDMI 256Byte)  

- Connect HDMI Signal Cable to HDMI Jack.
- Write EDID DATA to EEPROM(24C02) by using DDC2B

protocol.

- Check whether written EDID data is correct or not

4.5. Serial number (RS-232C)
