4. Total Assembly line process
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)
· Edge LED W/B Table is process of time(Only LGD)
CA210 : CH 14, Test signal : Inner pattern (85 IRE)
* Connecting picture of the measuring instrument
(On Automatic control)
Inside PATTERN is used when W/B is controlled. Connect to
auto controller or push Adjustment R/C POWER ON ->
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 10 cm 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 5 minutes.
- Using ‘no signal’ or ‘full white pattern’ or the others,
check the back light on.

RS-232C COMMAND
[CMD ID DATA]
Wb 00 00 White Balance Start
Wb 00 ff White Balance End
<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 Balance by pushing “
G” key at “6. White
Balance”.
* 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.
And Mechanical Power Switch must be set “ON”.
4.2. 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.
* For SVC main Assembly, EDID have to be downloaded to
Insert Process in advance.
4.3. 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.
* For SVC main Assembly, EDID have to be downloaded to
Insert Process in advance.
4.4. EDID DATA
1) All Data : HEXA Value
2) Changeable Data :
*: Serial No : Controlled / Data:01
**: Month : Controlled / Data:00
***:Year : Controlled
****:Check sum
