1-2-3 T1102_ISPPrecautions during ServicingA. Parts identified by the # symbol are critical forsafety.Replace only with part number specified.B. In addition to safety, other parts and assembliesare specified for conformance with regulationsapplying to spurious radiation. These must also bereplaced only with specified replacements.Examples: RF converters, RF cables, noiseblocking capacitors, and noise blocking filters, etc.C. Use specified internal wiring. Note especially:1) Wires covered with PVC tubing2) Double insulated wires3) High voltage leadsD. Use specified insulating materials for hazardouslive parts. Note especially:1) Insulation Tape2) PVC tubing3) Spacers4) Insulators for transistors.E. When replacing AC primary side components(transformers, power cord, etc.), wrap ends ofwires securely about the terminals beforesoldering.F. Observe that the wires do not contact heatproducing parts (heat sinks, oxide metal filmresistors, fusible resistors, etc.)G. Check that replaced wires do not contact sharpedged or pointed parts.H. When a power cord has been replaced, check that5~6 kg of force in any direction will not loosen it.I. Also check areas surrounding repaired locations.J. Be careful that foreign objects (screws, solderdroplets, etc.) do not remain inside the set.K. Crimp type wire connectorWhen replacing the power transformer in setswhere the connections between the power cordand power transformer primary lead wires areperformed using crimp type connectors, in order toprevent shock hazards, perform carefully andprecisely the following steps.Replacement procedure1) Remove the old connector by cutting the wiresat a point close to the connector.Important: Do not re-use a connector (discardit).2) Strip about 15 mm of the insulation from theends of the wires. If the wires are stranded,twist the strands to avoid frayed conductors.3) Align the lengths of the wires to be connected.Insert the wires fully into the connector.4) Use the crimping tool to crimp the metal sleeveat the center position. Be sure to crimp fully tothe complete closure of the tool.L. When connecting or disconnecting the DVD/VCRconnectors, first, disconnect the AC plug from theAC supply socket.
