    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, ensure that all the protective devices such as insulation barriers, insulation papers shields are properly installed.
  • Page 4: Before Repair And Adjustment

    1.2. Before Repair and Adjustment Main Unit (SU-HTB550) Disconnect AC power, discharge AC Capacitors as such C5700, C5701, C5702, C5703 and C5705 through a 10W, 1W 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.
