ADJUSTMENT INSTRUCTION
 
1. Application Range
This  specification  sheet  is  applied  all  of  the  LT33B  LED TV 
models, which produced in manufacture department or similar 
LG TV factory
2. Specification
(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.  But  it  is 
flexible when its factory local problem occurs.
(3)  The adjustment must be performed in the circumstance of 
25 ±5ºC of temperature and 65±10% of relative humidity if 
there is no specific designation.
(4)  The  input  voltage  of  the  receiver  must  keep  100~220V, 
50/60Hz.
(5) Before adjustment, execute Heat-Run for 5 minutes.
▪  After Receive 100% Full white pattern (06CH) then process 
Heat-run 
  (or “8. Test pattern” condition of Ez-Adjust status)
▪ How to make set white pattern 
1) Press Power ON button of Service Remocon
2)  Press ADJ  button  of  Service  remocon.  Select  “8.  Test 
pattern”  and,  after  select  “White”  using  navigation  button, 
and then you can see 100% Full White pattern. 
*  In this status you can maintain Heat-Run useless any pattern 
generator
* Notice :  if  you  maintain  one  picture  over  20  minutes 
(Especially sharp distinction black with white pattern 
-13Ch,  or  Cross  hatch  pattern  –  09Ch)  then  it  can 
appear image stick near black level.

    Program.
    *IP Number : 12.12.2.2.
4.2.2. 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
4.3.  ADC Adjust  =>  No  need  at Assembly 
line because of OPT type
* OTP mode
manufacture line, OTP is used 
for ADC Calibration automatically.
* External mode
Manual ADC  Calibration.    When  OTP  mode  is  failed, ADC 
calibration should be “OK” by 
using External mode.
- If you want re-adjust for ADC.
■ Enter Service Mode by pushing “ADJ” key,

Inside PATTERN is used when W/B is controlled. Connect to 
auto controller or push Adjustment R/C POWER-ON -> Enter 
the mode of White-Balance, the pattern will come out
● Auto-control interface and directions
(1)  Adjust  in  the  place  where  the  influx  of  light  like  floodlight 
around is blocked. (Illumination is less than 10ux).
(2)  Adhere closely the Color Analyzer ( CA210 ) to the module 
less  than  10cm  distance,  keep  it  with  the  surface  of  the 
Module and Color Analyzer’s Prove vertically.(80~100°).
(3) Aging time  
-  After aging start, keep the power on (no suspension of power 
supply) and heat-run over 5 minutes.
-  Using ‘no signal’ or ‘full white pattern’ or the others, check the 
back light on.
