02_Precaution.pdfPrecautions 1. Precautions Follow these safety, servicing and ESD precautions to prevent damage and protect against potential hazards such as electrical shock and X-rays. 1-1 Safety Precautions 1. Be sure that all of the built-in protective devices are replaced. Restore any missing protective shields. 2. When reinstalling the chassis and its assemblies, be sure to restore all protective devices, including: nonmetallic control knobs and compartment covers. 3. Make sure that there are no cabinet openings through which people--particularly children--might insert fingers and contact dangerous voltages. Such openings include the spacing between the picture tube and the cabinet mask, excessively wide cabinet ventilation slots, and improperly fitted back covers. If the measured resistance is less than 1.0 megohm or greater than 5.2 megohms, an abnormality exists that must be corrected before the unit is returned to the customer. 4. Leakage Current Hot Check (Figure 1-1): Warning: Do not use

05_Alignment & Adjustment.pdfAlignment 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 PVA to 45 (factory mode) and set SC as follows. 14, 16 inch : 0 20 inch : 10 21 inch : 12 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 fo
