Intelligent Sensor Inspection Guide; Lan Inspection; The Time Table Of Color - LG 47LM6400 Service Manual

● In case of Edge LED module, the color coordinates is
changing by aging, so you have to use the below table.
The Time Table of color coordinates by SET Aging Time
GP3 Aging Cool

1 0 ~ 2 279
2 3 ~ 5 278
3 6 ~ 9 277
4 10 ~19 276
5 20 ~ 35 274
6 36 ~ 49 272

9 Over 150 269
■ In the SET applied LED module (LS5700/LM6200/LM6600/
LM7600 Series), 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.)

Step 3. Block the Intelligent Sensor module on the front C/A
about 6 seconds.
333
When the "Sensor Data" is lower than 20, you can see the
330
"OK" message -> If it doesn't show "OK" message, the Sensor
Module is defected one.
327
You have to replace that with a good one.

Step 4. After check the "OK" message come out, take out your
hand from the Sensor module.
-> Check "Sensor Data" value change from "0" to "300" or not.
If it doesn't change the value, the sensor is also defected
one. You have to replace it.

5.4. LAN Inspection

1) LAN Port connection with PCB
2) Network setting at MENU Mode of TV
3) Setting automatic IP
4) Setting state confirmation
5) If automatic setting is finished, you confirm IP and MAC
