4.2.2.3. Adjustment
(1) Set TV in Adj. mode using POWER ON
(2) Zero Calibrate the probe of Color Analyzer, then place it on
the center of LCD module within 10cm of the surface.
(3) Press ADJ key -> EZ adjust using adj. R/C -> 6. White-
Balance then press the cursor to the right (KEY►). When
KEY(►) is pressed 216 Gray internal pattern will be
displayed.
(4) One of R Gain / G Gain / B Gain should be fixed at 192,
and the rest will be lowered to meet the desired value.
(5) Adj. is performed in COOL, MEDIUM, WARM 3 modes of
color temperature.
▪ If internal pattern is not available, use RF input. In EZ Adj.
menu 6.White Balance, you can select one of 2 Test-pattern:
ON, OFF. Default is inner(ON). By selecting OFF, you can
adjust using RF signal in 216 Gray pattern.
4.2.3. LED White balance table
4.2.3.1. Cool Mode
(1) Purpose : Especially G-gain fix adjust leads to the
luminance enhancement. Adjust the color
temperature to reduce the deviation of the
module color temperature.
(2) Principle : To adjust the white balance without the
saturation, Adjust the G gain more than 172 ( If
R gain or G gain is more than 255 , G gain can
adjust less than 172 ) and change the others (
R/B Gain ).
(3) Adjustment mode : mode – Cool
5.2.3.2. Medium / Warm Mode
(1) Purpose : Adjust the color temperature to reduce the
deviation of the module color temperature.
(2) Principle : To adjust the white balance without the
saturation,Fix the one of R/G/B gain to 192
(default data) and decrease the others.
(3) Adjustment mode : Two modes – Medium / Warm

▪ 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.)
4.4. 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
Address
