FOREWORD
For your convenience, all service parts, identified in this manual are available through Eiki's normal distribution channels.
In addition to service part number, the generic descriptions have been given, where possible, to allow your service
technicians to substitute equivalent components which might be available from other sources.
All orders for service parts will be honored. However, in instances where generic components are considered to be
available from several common sources, as would be the case with an industry standard fuse, resistor, or semicon-
ductor, it may be more economical and expeditious to purchase the part locally.

  • Page 10: Circuit Protections

    Circuit Protections This projector provides the following circuit protections to operate in safety. If the abnormality occurs inside the pro- jector, it will automatically turn off by operating one of the following protection circuits. Fuses (F601, F602, F603) Fuses are located inside of the projector. If all the indicators are not lighting, the fuse (F602) may be opened.

  • Page 11: Thermal Fuses (Sw903, Sw904, Sw905, Sw906)

    Circuit Protections Thermal fuses (SW903, SW904, SW905, SW906) There are the thermal fuses (SW903, SW904, SW905 and SW906) inside of the projector to detect the internal temperature rising abnormally. When the internal temperature around lamps reaches near 99˚C, the thermal fuse will open to cut off the power supply to the lamp power circuit.

  • Page 12: Temperature Sensors, Wind Sensors

    Circuit Protections Temperature sensors, wind sensors The projector provides 2 temperature sensor ICs, 1 sensor on the main board and 1 sensor on the ex temp board, and 1 wind sensor on the intake duct. The sensor ICs monitor surrounding temperature of the panels/prism, and surrounding temperature of the intake duct, and the wind sensor monitors airflow passed through the air filter in the intake duct.
