Alignment and Adjustments 4. Alignment and Adjustments 4-1 Preadjustment 4-1-1 Factory Mode 1. Do not attempt these adjustments in the Video Mode. 2. The Factory Mode adjustments are necessary when either the EEPROM (IC902) or the CRT is replaced. 3. Do not tamper with the "Adjustment" screen of the Factory Mode menu. This screen is intended only for factory use. 4-1-3 When CRT Is Replaced 1. Make the following adjustments AFTER setting up after setting up purity and convergence : White Balance Sub-Brightness Vertical Center Vertical Size Horizontal Size Fail Safe (This adjustment must be the last step). 2. If the EEPROM or CRT is replaced, set SC and PVA to 10 and 45 (Factory mode). SC : 14, 16 Inch : 0 20, 21 Inch : 10 4-1-2 When EEPROM (IC902) Is Replaced 1. When IC902 is replaced all adjustment data revert to initial values. It is necessary to re-program this data. 2. After IC902 is replaced, warm up the TV for 10 seconds. 4-2 Factory/Service Mode 4-2-1 Procedure for the "Adjustment" Mode 1. This mode uses the standard remote control. The Service Mode is activated by entering the following remote-control sequence : (1) SLEEPFACTORY. (2) STAND-BYP.STDHELPSLEEP POWER ON. 2. The "SERVICE (FACTORY)" message will be displayed. The Service Mode has four components: Adjustment, Test Pattern, Option Bytes and Reset. 3. Access the Adjustment Mode by pressing the "VOLUME" keys ( Up or Down). The adjustment parameters are listed in the accompanying table, and selected by pressing the CHANNEL keys (v ,w). 4. Selection sequences for the PAL system: DOWN or UP key: AGC>VCO>SBT>SCT>SCR>SC>RG> GG>BG>CDL>BLU>PSL>PVS>PVA>PHS 5. Selection sequences for the NTSC system: DOWN or UP key: AGC>VCO>SBT>SCT>SCR>SC>RG> GG>BG>CDL>BLU>NSL>NVS>NVA>NHS 6. The VOLUME keys increase or decrease the adjustment values, (stored in the non-volatile memory when Adjustment Mode is cancelled). 7. Cancel the Adjustment Mode by re-pressing the "FACTORY" or Power OFF.
