  • Page 3: Safety Precautions

    1 Safety Precautions 1.1. General Guidelines 1. When servicing, observe the original lead dress. If a short circuit is found, replace all parts which have been overheated or damaged by the short circuit. 2. After servicing, see to it that all the protective devices such as insulation barriers, insulation papers shields are properly installed.

  • Page 4: Before Repair And Adjustment

    1.4. Before Repair and Adjustment Disconnect AC power to discharge unit AC Capacitors as such (C5700,C5701, C5703, C5704, C5705, C5708) through a 10 Ω, 10 W resistor to ground. Caution: DO NOT SHORT-CIRCUIT DIRECTLY (with a screwdriver blade, for instance), as this may destroy solid state devices. After repairs are completed, restore power gradually using a variac, to avoid overcurrent.

    2.3. Service caution based on Legal restrictions 2.3.1. General description about Lead Free Solder (PbF) The lead free solder has been used in the mounting process of all electrical components on the printed circuit boards used for this equipment in considering the globally environmental conservation. The normal solder is the alloy of tin (Sn) and lead (Pb).

  • Page 9: Handling Precautions For Traverse Unit

    2.4. Handling Precautions for Traverse Unit The laser diode in the optical pickup unit may break down due to static electricity of clothes or human body. Special care must be taken avoid caution to electrostatic breakdown when servicing and handling the laser diode in the traverse unit. Cautions to Be Taken in Handling the Optical Pickup Unit 2.4.1.
  • Page 10 Grounding for electrostatic breakdown prevention 2.4.2. Some devices such as the DVD player use the optical pickup (laser diode) and the optical pickup will be damaged by static electric- ity in the working environment. Proceed servicing works under the working environment where grounding works is completed. 2.4.2.1.
