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)
- 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.
4.1.1 Auto-control interface and directions
1. Adjust in the place where the influx of light like floodlight
around is blocked. (illumination is less than 10ux).
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 15 minutes.
- Using ‘no signal’ or ‘full white pattern’ or the others, check the
back light on.
** 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 “•” key at “3. 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.
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 Ass’y, 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 Ass’y, EDID have to be downloaded to Insert
Process in advance.
