FOREWORD
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 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 semi-
conductor, 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 iden-
tified 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.
1: An isolation transformer should be connected in the DO NOT OPERATE THIS PROJECTOR WITHOUT
power line between the projector and the AC line THE PROTECTIVE SHIELD IN POSITION AND
before any service is performed on the projector. PROPERLY SECURED.
2: Comply with all caution and safety-related notes pro- 4: Before replacing the cabinet cover, thoroughly

or shields, barriers, etc.
PRODUCT SAFETY NOTICE
Product safety should be considered when a component replacement is made in any area of the projector.
Components indicated by mark ! in the parts list and the schematic diagram designate components in which
safety can be of special significance. It is, therefore, particularly recommended that the replacement of there parts
must be made by exactly the same parts.
SERVICE PERSONNEL WARNING
Eye damage may result from directly viewing the light produced by the Lamp used in this equipment. Always turn
off Lamp before opening cover. The Ultraviolet radiation eye protection required during this servicing.
Never turn the power on without the lamp to avoid electric-shock or damage of the devices since the stabilizer
generates high voltages(15kV - 25kV) at its starts.
Since the lamp is very high temperature during units operation replacement of the lamp should be done at least
45 minutes after the power has been turned off, to allow the lamp cool-off.

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.
Fuse Fuse Line Filter Board
The fuse is located inside of the projector. When either the LAMP
indicator or the READY indicator is not illuminated, fuse may be
opened. Check the fuse as following steps.
It should be used the specified fuse as follows;
FUSE PART NO. : 645 058 8181
TYPE 8A 250V FUSE
SKYGATE CO. LTD. TYPE SG-5013 008
How to replace the fuse
1. Remove the cabinet top following to "Mechanical
Disassemblies".
2. Remove the fuse from fuse holder.
To install the fuse, take reversed step in the above.
Thermal switch
There is the thermal switch (SW905) inside of the projector to Thermal switch
prevent the internal temperature rising abnormally. When the
internal temperature reaches near 90°C, turn off the AC main
power supply automatically.
The thermal switch is not reset to normal automatically even if the
internal temperature becomes normal. Reset the thermal switch
following procedure.
Check the resistance between terminals of thermal switch by
using the tester. If it has high impedance, thermal switch may be
in operative.
How to reset the thermal switch
1. Remove cabinet top following to the "Mechanical
Disassemblies".
2. Press the reset button on the thermal switch.
CAUTION:
Before press the reset button, make sure that the AC cord must
be disconnected from the AC outlet. Lamp cover
Interlock switch
Interlock switch
The interlock switch (SW902) cuts off the AC mains power supply
when the lamp cover is removed. After opening the lamp cover for
replacing the lamp ass'y, place the lamp cover correctly otherwise
the projector can not turn on.

Circuit Protections
Warning temperature and power failure protection
The projector will be automatically turned off when the internal temperature of the projector exceeds the normal oper-
ating temperature, or the cooling fans stops, or the power supplies in the projector are failed.
- If the TEMP WARNING indicator (red) is flashing, it may detect the abnormal temperature inside the projector.
Check the following possible causes and wait until the WARNING TEMP indicator flashing stops, and then try to
turn on the projector.
- If both of the TEMP WARNING (red) and READY (green) indicators are flashing at the same time, It may defect the
cooling fans and power supply circuits. Check fan operation and power supply lines referring to the chapter "Power
supply & protection circuit" in the Chassis Block Diagram section.
Possible causes
- Air filter is clogged with dust particles. Remove dust from the air filter by following instructions in the "Air filter
care and cleaning" below.
- Ventilation slots of the projector are blocked. In such an event, reposition the projector so that ventilation slots are
not obstructed.
- Check if projector is used at higher temperature place (Normal operating temperature is 5 to 35 °C or 41 to 95°F)
Air filter care and cleaning
The removable air filters prevent dust from accumulation on the surface of the projection lens and projection mirror.
Should the air filter become clogged with dust particles, it will reduce the cooling fan's effectiveness and may result
in internal heat build up and reduce the life of the projector.
To clean up the air filters, follow the cleaning procedure
below:
1. Turn the power off, and disconnect the AC power cord Air filters
from the AC outlet.
2. Turn the projector up side down and remove air filters
by pulling the latches of them upward.
3. Clean the air filters with brush or wash out the dust and
particles.
4. Replace each air filter properly. Make sure that the air
filters are fully inserted.
CAUTION:
Do not operate the projector with the air filter removed. The
dust is stuck on the LCD panel and the mirror, and it may
spoil the fine picture image.
Do not put the small parts into the air intake vents. It may
result in the malfunction of the projector. The air filters are
small parts. Take care that children don't eat or swallow it.
RECOMMENDATION
We recommend not to use the projector in dusty, smoky places. Using it in dusty place may cause the poor picture
quiality.
When using under the dusty or smoky conditions, dust may accumulate on the LCD panel and lens inside it, and
may resultantly be projected on the screen together with the picture.
When the above symptoms are noticed, please clean up the LCD panel and lens following to the "Cleaning
Method".
