ADJUSTMENT INSTRUCTION
1. Application Range
This  specification  sheet  is  applied  to  all  of  the  LED TV  with 
LB33B 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 °C.
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.  MAC  address  D/L,  HDCP1.4/HDCP2.0 
key D/L,Widevine key D/L, ESN D/L
Connect: USB port 
Communication Prot connection
▪ Com 1,2,3,4 and 115200(Baudrate)
  Mode check: Online Only
▪  Check  the  test  process:  DETECT  ->  MAC  ->  Widevine  -> 
ESN -> HDCP14 -> HDCP20
▪ Play: Press Enter key
▪ Result: Ready, Test, OK or NG
▪ Printer Out (MAC Address Label)
3.2. LAN Inspection
3.2.1. Equipment & Condition
▪ Each other connection to LAN Port of IP Hub and Jig
3.2.2. LAN inspection solution
▪ LAN Port connection with PCB
▪ Setting automatic IP
▪  If you want manual connection, enter Network connection at 
MENU  Mode  of  TV.  Press  Start  connection  key,  then 
Network will be connected.
▪ Setting state confirmation
-  If  automatic  setting  is  finished,  you  confirm  IP  and  MAC 
Address at ‘in start’ menu mode.

3.2.3. WIDEVINE key Inspection
- Confirm key input data at the "IN START" MENU Mode.
3.3. LAN PORT INSPECTION(PING TEST)
Connect SET → LAN port == PC → LAN Port
3.3.1. Equipment setting
(1) Play the LAN Port Test PROGRAM.
(2) Input IP set up for an inspection to Test Program.
*IP Number : 12.12.2.2
3.3.2. LAN PORT inspection(PING TEST)
(1) Play the LAN Port Test Program.
(2) Connect each other LAN Port Jack.
(3) Play Test (F9) button and confirm OK Message.
(4) Remove LAN cable.
3.4. Model name & Serial number Download
3.4.1. Model name & Serial number D/L
 Press "P-ONLY" key of service remote control.
(Baud rate : 115200 bps)
 Connect RS-232C Signal to USB Cable to USB.
 Write Serial number by use USB port.
 Must check the serial number at Instart menu.
3.4.2. Method & 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.
* Manual Download (Model Name and Serial Number)
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 Adjustment remote control.
2) Go to the menu "7.Model Number D/L" like below photo.
3)  Input the Factory model name(ex 42LM7600-TA) or Serial 
number like photo.
4)  Check  the  model  name  Instart  menu.  →  Factory  name 
displayed. (ex 42LM7600-TA)
5)  Check  the  Diagnostics.(DTV  country  only)  →  Buyer
