Note on Servicing When you carry out the electrical, optical service adjustment or repairing with cabinet top removal, it should be done under the service conditions listed below. If you can not keep the one of following conditions, the projector turns off automatically by operating the protection circuit.
Circuit Protections This projector is equipped with the following circuit protections to operate in safety. If the abnormality occurs inside the projector, it will automatically turn off by operating one of the following protection circuits. Fuse The fuse is located inside of the projector. When either the LAMP indicator or the READY indicator is not illuminat- ed, fuse may be opened.
Circuit Protections Warning temperature and power failure protection The TEMP WARNING indicator flashes red and the projector will automatically turn off when the internal tempera- ture of the projector exceeds the normal temperature or when stopping cooling fans or when the internal power supply lines are failed.
Mechanical Disassemblies Mechanical disassemble should be made following procedures in numerical order. Following steps show the basic procedures, therefore unnecessary step may be ignored. Caution: The parts and screws should be placed exactly the same position as the original otherwise it may cause loss of performance and product safety.
