4.Alignment and Adjustment   |\n| --- |\n| 4-1 Preadjustment   |\n\n4-1-1 Factory Mode  \n1.Do not attempt these adjustments in the Videomode.  \n2.The Factory Mode adjustments are necessarywhen either the EEPROM (IC902)or the CRT isreplaced.  \n3.Do not tamper with the\"Adjustment\"screen ofthe Factory Mode menu.This screen isintended only for factory use.  \n# 4-1-2 When EEPROM(IC902)Is

Factory/Service Mode            \n4-2-1 Procedure for the \"Adjustment\"Mode  \n1.This mode uses the standard remote controlThe Service Mode is activated by(1)pressingthe \"HIDDEN\"service key on the local-keyboard,or(2)by entering the followingremote-control sequence:  \nSTAND-BY→P.STD→HELP→SLEEP→POWER ON  \n2.The \"SERVICE(FACTORY)\"message will bedisplayed.The Service Mode has fourcomponents:Adjustment,Test Pattern,OptionBytes and Reset.  \n3.Access the Adjustment Mode by pressing the\"VOLUME\"keys(Upor Down).Theadjustment parameters are listed in theaccompanying table,and selected by pressingthe CHANNEL keys(▲,▽).  \n4-1-3 When CRTIs Replaced  \n1.Make the following adjustments AFTERsetting up after setting up purity andconvergence:  \nWhite BalanceSub-BrightnessVertical Center (VR302)Vertical Size(VR301)Horizontal Size  \nFail Safe(This adjustment must be the laststep.)  \n2.If the EEPROM or CRT is replaced,set PSLand PVA to 15 and

sequences for the NTSC system:  \nDOWN or UP key:AGC>SBT>SCT>SCR>STT>NDLRC>GC>BC>RG>BG>NSLNVS>NVANHS  \n6.The VOLUME keys increase or decrease theadjustment values,which are stored in thenon-volatile memory when Adjustment modeis cancelled.  \n7.Cancel the Adjustment Mode by repressing the\"HIDDEN\"key or the \"STATUS\"key.  \n4-2-2 Main Adjustment Parameter  \n\n| Table 4-1 Main Adjustment
