ADJUSTMENT INSTRUCTION
1. Application Range
This specification sheet is applied to all of the LED LCD TV 
with LB23J chassis.
2. Designation
(1)  Because  this  is  not  a  hot  chassis,  it  is  not  necessary  to 
use an isolation transformer. However, the use of isolation 
transformer will help protect test instrument.
(2) Adjustment must be done in the correct order. 
(3)  The adjustment must be performed in the circumstance of 
25 °C ± 5 °C of temperature and 65 % ± 10 % of relative 
humidity if there is no specific designation. 
(4)  The  input  voltage  of  the  receiver  must  keep AC  100-240 
V~, 50/60 Hz.
(5)  The receiver must be operated for about 5 minutes prior to 
the adjustment when module is in the circumstance of over 
15.
In case of keeping module is in the circumstance of 0 °C, it 
should be placed in the circumstance of above 15 °C for 2 
hours.
In case of keeping module is in the circumstance of below 
-20 °C, it should be placed in the circumstance of above 15 
°C for 3 hours.
[Caution] 
When  still  image  is  displayed  for  a  period  of  20  minutes  or 
longer  (Especially  where  W/B  scale  is  strong.  Digital  pattern 
13ch  and/or  Cross  hatch  pattern  09ch),  there  can  some 
afterimage in the black level area.
3. Automatic Adjustment
3.1. ADC Adjustment
3.1.1. Overview
ADC  adjustment  is  needed  to  find  the  optimum  black  level 
and gain in Analog-to-Digital device and to compensate RGB 
deviation.
3.1.2. Equipment & Condition
(1) USB to RS-232C Jig 
(2)  MSPG-925  Series  Pattern  Generator(MSPG-925FA, 
pattern - 65)
- Resolution : 480i Comp1
 
1080P Comp1
 
1920*1080 RGB
- Pattern : Horizontal 100% Color Bar Pattern
- Pattern level : 0.7 ± 0.1 Vp-p
- Image
3.1.3. Adjustment
(1) Adjustment method
-  Using  RS-232,  adjust  items  in  the  other  shown  in 
"3.1.3.3)"
(2) Adj. protocol
Ref.) ADC Adj. RS232C Protocol_Ver1.0
(3) Adj. order
- aa 00 00 [Enter ADC adj. mode]
-  xb 00 04 [Change input source to Component1 (480i& 
1080p)]
- ad 00 10 [Adjust 480i&1080p Comp1]
- xb 00 06 [Change input source to RGB(1024*768)]
- ad 00 10 [Adjust 1920*1080 RGB]
- ad 00 90 End adj.

3.3. LAN
3.3.1. Equipment & Condition
▪ Each other connection to LAN Port of IP Hub and Jig
3.3.2. LAN inspection solution
▪ LAN Port connection with PCB
▪ Network setting at MENU Mode of TV
▪ Setting automatic IP
▪ Setting state confirmation
->  If  automatic  setting  is  finished,  you  confirm  IP  and  MAC 
Address.
3.3.3. WIDEVINE key Inspection
- Confirm key input data at the "IN START" MENU Mode.
3.4. LAN PORT INSPECTION(PING TEST)
Connect SET -> LAN port == PC -> LAN Port
3.4.1. Equipment setting
