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 cir-
cuit is identified with the line ( ) in the schematic diagram. For con-
tinued product safety and protection of personnel injury, servicing
should be made with qualified personnel.
The following precautions must be observed.
Caution "HOT CIRCUIT"
Lamp Unit
Lamp ballast Unit
Power supply Unit
P.F.C. unit
SAFETY PRECAUTIONS
1: An isolation transformer should be connected in the power line between the projector and the AC line
before any service is performed on the projector.
2: Comply with all caution and safety-related notes provided on the cabinet back, cabinet bottom, inside the
cabinet or on the chassis.
3: When replacing a chassis in the cabinet, always be certain that all the protective devices are installed
properly, such as, control knobs, adjustment covers or shields, barriers, etc.
DO NOT OPERATE THIS PROJECTOR WITHOUT THE PROTECTIVE SHIELD IN POSITION AND PROP-
ERLY SECURED.
4: Before replacing the cabinet cover, thoroughly inspect the inside of the cabinet to see that no stray parts
or tools have been left inside.
Before returning any projector to the customer, the service personnel must be sure it is completely safe to
operate without danger of electric shock.
Safety Instructions
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 the
parts must be made by exactly the same parts.
Caution:
The parts and screws should be placed exactly the same position as the original otherwise it may cause lose of
performance and product safety.
The wiring method of the leads should be returned exactly the same state as the original otherwise it may cause
lose of performance and product safety.

DO NOT ATTEMPT TO SERVICING THE REMOTE
CONTROL UNIT.
Laser Beam may be leaked out when in disassemble
the Unit. As the Laser Beam used in this Remote
control unit is harmful to the eyes.
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 is 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 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.

This projector is equipped with the following protections to operate in safety.
Protections
❏ Fuse for circuit protection
The fuse is located in the rear inside a projector. (Refer to figure.) When
either the LAMP indicator or the READY indicator is not illuminated,
fuse may be opened. Check the fuse as following steps.
1. Remove the Cabinet-top following to “Mechanical Disassemblies”.
2. Remove the fuse from fuse holder. (Refer to right figure.)
Turns the fuse holder cover with the slot screw driver.
Remove the fuse and the fuse holder cover upward.
3. Check the resistance of fuse using a tester.
To install the fuse, take reversed step in the above.
It should be used the specified fuse as follows;
❏ Protection equipment for users Electric shock protection. (Interlock switch)

■ The Lamp circuit (the lamp and the electrode of the lamp socket)of this
projector is not insulated from AC line, and it is "HOT." Therefore,
when replacing lamp assembly, an electric shock may be received.
However, the interlock switch (SW902) is designed so that it may pro-
tect from the accident.
■ This switch (SW902) insulates a lamp circuit from AC line, when
cover-top is opened. (The lamp circuit changes to "COLD.")

❏ Overheating Protection -- The temperature monitor system --
----- The temperature monitor -1: -----
■To control the driving power of the cooling fans.
The CPU checks the temperature and atmospheric pres-
sure inside a projector. It checks a temperature using
temperature sensor-IC5801and it checks an atmospheric
pressure using pressure sensor-IC4849.
The CPU controls the driving power of the cooling fans
so the temperature inside the projector is maintained to
normal temperature.
■To shut down the projector.
The CPU checks temperature of Blue polarization glass
(PTH901) and inhalation air(IC5801). If each part tem-
perature reaches to abnormal temperature, the CPU will
turn off a projector, and will blink WARNING TEMP.
indicator at intervals of 0.6 seconds. Cooling fans operate
until temperature returns to normal. Indicator will stop
blink, if temperature returns to normal.
The temperature monitor system is provided to prevents damage of optical components (the LCD panel and polarization film
etc.) inside a projector from overheat. Two protection systems are provided.
Each system operation as follows ;
----- The temperature monitor -2 : -----
(Temperature check of lamps. )
Temperature switches (SW 903~906) are arranged near
the four lamps. Temperature switches will operate, if
temperature reaches 100 degrees.
SW (903~906) ----- It operates at 100 degrees.
(Lamp-1~4)
When temperature switches have operated, lamp ballast
units will be shut down, then a projector will be turned
off.
Note. The CPU does not check operation of temperature
switches. Therefore, when temperature switches have
operated and a projector has shut down, WARNING
TEMP. indicator does not blink.

CARRYING AND TRANSPORTING A PROJECTOR
●Do not drop or bump a projector, otherwise damages or malfunctions may result.
●When carrying a projector, use a suitable carrying case.
●Do not transport a projector by using a courier or transport service in an unsuitable transport
case. This may cause damage to a projector. To transport a projector through a courier or
transport service, consult your dealer and best case should be applied.
CAUTION IN CARRYING OR TRANSPORTING A PROJECTOR
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.
●If the projector indicates that the lamp should be replaced, i.e., if the LAMP REPLACE INDICATOR lights up,
replace the lamp with a new one IMMEDIATELY after the projector has cooled down.
( Follow carefully the instructions in the LAMP REPLACEMENT section of owner's manual. ) Continuous use
of the lamp with the LAMP REPLACE INDICATOR lighted may increase the risk of lamp explosion.
●A Lamp may explode as a result of vibration, shock or degradation as a result of hours of use as its lifetime
draws to an end. Risk of explosion may differ according to the environment or conditions in which the
projector and lamp are being used.
IF A LAMP EXPLODES, THE FOLLOWING SAFETY PRECAUTIONS SHOULD BE TAKEN.
If a lamp explodes, disconnect the projector’s AC plug from the AC outlet immediately. Contact an authorized
service station for a checkup of the unit and replacement of the lamp. Additionally, check carefully to ensure
that there are no broken shards or pieces of glass around the projector or coming out from the cooling air
circulation holes. Any broken shards found should be cleaned up carefully. No one should check the inside of
the projector except those who are authorized trained technicians and who are familiar with projector service.
Inappropriate attempts to service the unit by anyone, especially those who are not appropriately trained to do so,
may result in an accident or injury caused by pieces of broken glass.
