▪ 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.)
4.3. 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
Address
4.4.WIDEVINE Key Inspection
(1) Confirm Key input Data at the “IN START” MENU Mode
4.5. Model name & Serial number D/L
4.5.1. Notice
(1) Serial number D/L is using of scan equipment.
(2) Setting of scan equipment operated by Manufacturing
Technology Group.
(3) Serial number D/L must be conformed when it is produced
in production line, because serial number D/L is mandatory
by D-book 4.0
(4) Check the model name In-start menu -> Factory name
displayed
(5) Check the Diagnostics (DTV country only) -> Buyer model
displayed
4.5.2. Method : Auto
(1) Press “Power on” key of service remocon.(Baud rate :
115200 bps)
(2) Connect RS232 Signal Cable to RS-232 Jack
(3) Write Serial number by use RS-232.
(4) Must check the serial number at Instart menu.
4.5.3. Method : Manual
* If the TV set is downloaded By OTA or Service man,
Sometimes model name or serial number is initialized.
(Not always) It is impossible to download by bar code scan, so
It need Manual download.
(1) Press the ‘instart’ key of ADJ remote controller.
(2) Go to the menu ‘6.Model Number D/L’ like below photo.
(3) Input the Factory model name or Serial number like photo.
