Enter the mode of White-Balance, the pattern will come out.

* Auto-control interface and directions

1) Adjust in the place where the influx of light like floodlight

around is blocked. (illumination is less than 10 Lux).

2) Adhere closely the Color Analyzer (CA210) to the module

less than 10cm distance, keep it with the surface of the
Module and Color Analyzer’s Prove vertically.(80~100°).

3) Aging time

- After aging start, keep the power on (no suspension of

power supply) and heat-run over 15minutes.

- Using ‘no signal’ or ‘full white pattern’ or the others,

check the back light on.

In the SET applied LED module, as to physical characteristics
of LED Module, the sets takes a 120 minutes by aging time to
stabilize a color coordinates. So White Balance Control
equipments get the SET Aging Time from SET and then going
to control the W/B by revise color coordinates in the each time

Cautions) The Time Table of color coordinates by SET Aging Time

** 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.

Dynamic contrast : off
Dynamic color : off
OPC : off
Energy saving mode : off

- After enter Service Mode by pushing “ADJ” key,
- Enter White Balance by pushing “

Cautions) The Time Table of color coordinates by SET Aging Time

* 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.

* Push The “IN STOP” key after completing the function

inspection.

(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

• 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.
* For SVC main Ass’y, EDID have to be downloaded to Insert

Process in advance.

• 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.
* For SVC main Ass’y, EDID have to be downloaded to Insert

Process in advance.

1) All Data : HEXA Value
2) Changeable Data
*: Serial No : Controlled / Data:01
**: Month : Controlled / Data:00
***:Year : Controlled
****:Check sum

• After enter Service Mode by pushing “ADJ” key,
• Enter EDID D/L mode.
• Enter “START” by pushing “OK” key.

* Edid data and Model option download (RS232)

<Caution>
- Never connect HDMI & D-sub Cable when the user downloading .
- Use the proper cables below for EDID Writing.

* Caution

1) Use the proper signal cable for EDID Download

- Analog EDID : Pin3 exists
- Digital EDID : Pin3 exists

2) Never connect HDMI & D-sub Cable at the same time.
3) Use the proper cables below for EDID Writing.
4) Download HDMI1, HDMI2, separately because HDMI1 is

different from HDMI2.
