Refer to Standard of LG(55)G1-1020
1. Application Range
This spec. sheet is applied to all of the LP62F chassis(H3-
High) manufactured at LG TV Plant all over the world.  
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 to protect test instruments.
2) Adjustment must be done in the correct sequence.
3) The adjustment must be performed at 25±5°C temperature
and 65±10% relative humidity if there is no specified
designation.
4) The input voltage of the receiver must be kept between
100-220V, 50/60Hz.
5) Before adjustment, execute Heat-Run for 30 minutes at RF
no signal
3. Adjustment items 
3.1. PCB assembly adjustment items

G
(Vol. +) key operate To set , then it becomes
automatically.
5) Auto-RGB OK means adjustment is completed.
* Before White-balance, the AV ADC should be done.
(ZH:AV3, TH:AV1, MH:VIDEO1)
Notice : Before White-balance, change input mode.
Move to AV3(ZH) or AV1(TH) or VIDEO1(MH) by using
the FRONT-AV KEY on Remote controller.
6. White Balance
