Precautions 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.
Precautions 1-1 Safety Precautions (Continued) 9. High voltage is maintained within specified limits by close-tolerance, safety-related components and adjustments. If the high voltage exceeds the specified limits, check each of the special components. 10. Design Alteration Warning: Never alter or add to the mechanical or electrical design of this unit. Example: Do not add auxiliary audio or video connectors. Such alterations might create a safety hazard.
Precautions 1-2 Servicing Precautions Warning1: First read the “Safety Precautions” section of this manual. If some unforeseen circumstance creates a conflict between the servicing and safety precautions, always follow the safety precautions. Warning2: An electrolytic capacitor installed with the wrong polarity might explode. 1. Servicing precautions are printed on the cabinet. Follow them. 2.
Precautions 1-3 Precautions for Electrostatically Sensitive Devices (ESDs) 1. Some semiconductor (Òsolid stateÓ) devices are easily damaged by static electricity. Such components are called Electrostatically Sensitive Devices (ESDs); examples include integrated circuits and some field-effect transistors. The following techniques will reduce the occurrence of component damage caused by static electricity. 2.

Disassembly and reassembly 3. Disassembly and Reassembly 3-1 Back Cover Removal 1. After removing the screws, press the tension rib and pull the cabinet backwards. 2. To reassemble, press the tension rib (see diagram).
Disassembly and reassembly 3-2 Main Board Removal 1. Separate the socket board from the CRT neck. 2. Remove the Anode Cap from the CRT. 3. Remove the main board by pulling it with both hands. Warning: The FBT is charged with high voltage. Before removing the Anode Cap, discharge the voltage through one of the heat sinks on the main board.
Disassembly and reassembly 3-3 Speaker Removal 1. Remove the speaker by pressing the tension rib. 1. Remove the screws. 2. Remove the speaker by pressing the tension rib.
Disassembly and reassembly 3-4 CRT Removal 1. Spread a soft mat on the floor. Place the TV set face down. 2. Remove the 4 nuts mounting the CRT to the front cabinet. Lift the CRT. 3. Caution: Because of the high vacuum and large surface area of the picture tube, be careful while handling it: (1) Always lift the picture tube by grasping it firmly around the faceplate, (2) Never lift the tube by its neck. (3) Do not scratch the picture tube or apply excessive pressure.
Alignment and Adjustments 4. Alignment and Adjustments 4-1 Preadjustment 4-1-1 Factory Mode 4-1-3 When CRT Is Replaced 1. Do not attempt these adjustments in the Video Mode. 1. Make the following adjustments AFTER setting up after setting up purity and convergence : 2. The Factory Mode adjustments are necessary when either the EEPROM (IC902) or the CRT is replaced. 3. Do not tamper with the ÒAdjustmentÓ screen of the Factory Mode menu. This screen is intended only for factory use.
