■ In the SET applied LED module (LM9600), cause of the physical
characteristics of LED Module, sets are taken a 120 minutes by
aging time to stabilize a color coordinates.
So White Balance Control equipments have to get the SET Aging
Time from the SET and then going to control the W/B by revise
color coordinates at each time
- To check the Coordinates of White Balance, you have to measure
at the below conditions.
Picture Mode : select Vivid and change
Dynamic Contrast : Off ,
Dynamic Colour : Off,
Clear White : Off
=> Picture Mode change : Vidid => Vivid(User)
(If you miss the upper condition, the coordinates of W/B can be
lower than the spec.)
※
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 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 5 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 “7. White Balance”.
※
After You finish 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 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.
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
- Auto Download
■ After enter Service Mode by pushing “ADJ” key,
■ Enter EDID D/L mode.
■ Enter “START” by pushing “OK” key.
