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 serv-

ice 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

semiconductor, it may be more economical and expeditious to purchase the part locally.

■ Safety Instructions SAFETY PRECAUTIONS WARNING: The chassis of this projector is isolated (COLD) from AC line by using the converter transformer. Primary side of the converter and lamp power supply unit circuit is connected to the AC line and it is hot, which hot circuit is identified with the line ( ) in the schematic diagram. For continued product safety and protection of personnel injury, servicing should be made with qualified personnel. The following precautions must be observed.

■ Circuit Protections This projector provides 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 A fuse(F901) is located inside of the projector. When the POWER indicator is not lighting, the fuse may be opened. Check the fuse as following steps. The fuse should be used with the following type; Holder PLC-XT4U Fuse Part No.: 423 033 1804 TYPE 30.

Circuit Protections When both of the WARNING TEMP. and READY Indicators are flashing: When the projector detects an internal problem, it will shut down automatically and both of the WARNING TEMP. and READY Indicators starts flashing. In this condition, the projector cannot be turned on even if you press the POWER ON-OFF button on the remote control unit or on the side control. If this case happened, disconnect and reconnect the AC power cord, and then turn on the projector again to check its operation.
PAGE 7
Circuit Protections When the WARNING TEMP. Indicator is flashing: The WARNING TEMP. Indicator flashes red to let you know the internal temperature of the projector exceeds the normal level. If the temperature goes up further, the projector will be turned off automatically and the Ready indicator will go out. (The WARNING TEMP. Indicator continues flashing.

Circuit Protections ● Temperature Monitor System ■ To control the driving power of the cooling fans. This projector detects internal temperature and automatically controls operating power of cooling fans. The CPU checks the temperature and atmospheric pressure inside a projector. It checks a temperature using temperature sensor-IC5801and it checks an atmospheric pressure using pressure sensor-IC886.

■ Lamp Replacement LAMP MANAGEMENT (before replacement) This Projector is equipped with 4 Projection Lamps to ensure brighter image and those lamps are controlled by Lamp Management Function. Lamp Management Function detects status of all lamps and shows status on screen or on LAMP REPLACE indicator. This function also automatically controls Lamp Mode when any of lamps is out for end of life or malfunctions.
PAGE 10
Lamp Replacement LAMP REPLACEMENT When the life of the projection lamp of this projector draws to an end, the LAMP REPLACE indicator lights yellow. If this indicator lights yellow, replace the lamp with a new one promptly. The time when the LAMP REPLACE indicator lights is depending on the lamp mode. FRONT INDICATORS REAR INDICATORS LAMP READY WARNI TEMP.NG LA P REPLM ACE LAMP READY LAMP REPLACE WARNING : TURN OFF THE UV LAMP BEFORE OPENING THE LAMP COVER.
PAGE 11
Lamp Replacement CAUTION For continued safety, replace with a lamp assembly of same type. Allow a projector to cool for at least 45 minutes before you open Lamp Cover. Inside of a projector can become very hot. CAUTION HIGH VOLTAGE HOT CAUTION Do not drop a lamp assembly or touch a glass bulb! Glass can shatter and may cause injury. LAMP REPLACE COUNTER Be sure to reset Lamp Counter when Lamp Assembly is replaced. When Lamp Replace Counter is reset, LAMP REPLACE indicator stops lighting.
PAGE 12
Lamp Replacement LAMP HANDLING PRECAUTIONS This projector uses a high-pressure lamp which must be handled carefully and properly. Improper handling may result in accidents, injury, or create a fire hazard. ● Lamp lifetime may differ from lamp to lamp and according to the environment of use. There is no guarantee of the same lifetime for each lamp. Some lamps may fail or terminate their lifetime in a shorter period of time than other similar lamps.
PAGE 13
■ Maintenance and Cleaning After long periods of use, dust and other particles will accumulate on the LCD panel, prism, mirror, polarized glass, lens, etc., causing the picture to darken or color to blur. If this occurs, clean the inside of optical unit. Remove dust and other particles using air spray. If dirt cannot be removed by air spray, disassemble and clean the optical unit. ● Cleaning with air spray 1. Remove the cabinet top following to "Mechanical Disassemblies". 2.
PAGE 14
Maintenance and Cleaning AIR FILTER CARE AND CLEANING Air Filter prevents dust from accumulating on surface of Projection Lens and Projection Mirror. Should Air Filter become clogged with dust particles, it will reduce Cooling Fans' effectiveness and may result in internal heat build up and adversely affect life of a projector. Clean Air Filter following steps below: 1 Turn power off, and disconnect AC power cord from AC outlet. 2 Pull out air filter unit from the projector.
PAGE 15
■ Mechanical Disassemblies 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. The wiring method of the leads and ferrite cores should be returned exactly the same state as the original, otherwise it may cause loss of performance and product safety.
