SERVICE MANUAL

Give complete " Chassis No. " for parts
order or servicing, it is shown on the
rating sheet on the cabinet on the projector.
For your convenience, all service parts, identified in this manual are available through Eiki's normal distribution chan-
nels. 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 5: 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. Thermal switch There is the thermal switch (SW902) inside of the projector to de- tect the internal temperature rising abnormally.

  • Page 6: Warning Temperature And Power Failure Protection

    Circuit Protections Warning temperature and power failure protection The projector will be automatically turned off when the internal temperature of the projector is abnormally high, or the cooling fans stop spinning, or the power supplies in the projector are failed. - If the WARNING indicator is flashing, it may detect the abnormal temperature inside the projector.

  • Page 7: Maintenance

    Maintenance Cleaning the Filter Filter prevents dust from accumulating on the optical elements inside the projector. Should the filters become clogged with dust particles, it will reduce cooling fans’ effectiveness and may result in internal heat buildup and adversely affect the life of the projector. If a Filter warning icon appears on the screen, clean the filters immediately.
