ADJUSTMENT INSTRUCTION
1. Application Range
This specification sheet is applied all of the LJ03R LCD TV
models, which produced in manufacture department or similar
LG TV factory 
2. Notice 
(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 ºC ± 5 ºC of temperature and 65 % ± 10 % of relative
humidity if there is no specific designation. 
(4) The input voltage of the receiver must keep AC 100-220
V~ 50 / 60Hz.
(5) Before adjustment, execute Heat-Run for 5 minutes. 
A
After Receive 100% Full white pattern (06CH) then
process Heat-run  
(or “8. Test pattern” condition of Ez-Adjust status) 
A
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.
