ADJUSTMENT INSTRUCTION
1. Application Range
This specification sheet is applied all of the LJ22E LCD 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.
3. Adjustment items
3.1. PCB Assembly Adjustment
▪ MAC Address / ESN / Widevine Download
▪ Adjust 1080p Comp1/RGB (Except GP3 BCM MODEL using
ADC OTP)
▪ EDID (The Extended Display Identification Data)/DDC
