Safety Instructions
For continued product safety and protection of personnel injury,
servicing should be made with qualified personnel.
Risk of electric shock
Assembly power ,
Assembly PFC,
Assembly lamp ballast and
Assembly lamp are
"HOT" .
The signal circuit and control circuit of this projector are insu-
lated (COLD) from AC line by the insulation transformer
inside the projector. But, assembly power, assembly PFC, assem-
bly lamp ballast and assembly lamp are not insulated from AC
line, and those are "HOT."
HOT CIRCUIT IS IDENTIFIED WITH THE LINE (
) IN THE SCHEMATIC DIAGRAM.
An insulation transformer should be connected in the power
line between the projector and the AC line before the service
of hot circuit is performed on the projector.
Laser Beam
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.
NOTE; Laser radiation
Max output ; 1mW
Wave length ; 650 ± 20nm
Class II laser product
Cooling Fan
The fan's attachment method is special significance instruction
to product safety. If attachment direction of fan make a mis-
take, the projector overheats and result in fire hazard.
Safety significant parts
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 spe-
cial significance. It is, therefore, particularly recommended
that the replacement of the parts must be made by exactly the
same parts.
Light source lamp
Do not view directly the light emitted by the lamp used in this
projector. The light emitted is very strong and include ultra-
violet ray. Protect the eyes and the skin from light and ultra-
violet ray during this servicing.
Pay attention to service of lamp circuit , to avoid electric-shock
or damage of the devices since the lamp circuit generates high
voltages (20~25kV) at its starts.
The lamp is very high temperature during units operation. Be
careful not to burn oneself since a hot state continues for the
time being, after turning off a projector. We recommend ser-
viceing after turning off a projector and leaving it for at least
45 minutes.
Other
Do not leave the tool or the obstacle near the exhaust vents and
air intake vents of the projector during service of the projector.
It may cause unusual overheat inside the projector. Air blown
from exhaust vent is hot. Do not put spray-can and flammable
object near the exhaust vent.
Comply with all caution and safety-related notes provided on
the cabinet back, cabinet bottom, inside the cabinet or on the
chassis.
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 oper-
ate this projector without the protective shield in position and
properly secured. Before replacing the cabinet cover, thor-
oughly inspect the inside of the cabinet to see that no stray
parts or tools have been left inside.

This projector is equipped with the following protections
to operate in safety.
❏ Fuse for circuit protection
Protections
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.
To install the fuse, take reversed step in the above.
3. Check the fuse using a tester.
Fuse is safety significant part.
It should be used the specified fuse as follows;

■ Protection equipment for lamp replacement :
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 protect from the accident.
■ This switch(SW902) insulates a lamp circuit from AC line, when lamp cover is removed.
(The lamp circuit changes to "COLD.")
■ The note for service-personnel :
Push in and hold the lever of the interlock switch when the projector turns on by state of
no cabinet.

----- The temperature monitor -1: -----
■To control the air-flow of the cooling fans.
The CPU checks the temperature and atmospheric pressure inside a projector.
It checks a temperature using temperature sensor-IC5801 and it checks an
atmospheric pressure using pressure sensor-IC886.
CPU judges data from sensors and controls the air flow of the cooling fans so
the temperature inside the projector is maintained to normal temperature.
■To shut down the projector urgent.
The CPU checks temperature of Red-LCD panel periphery (IC2541) and
inhalation air(IC5801). If each part temperature reaches to abnormal temper-
ature(IC2541 ; 47degrees / IC5801 ; 42degrees),
the CPU will turn off a projector, and will blink TEMPERATURE WARN-
ING indicator at intervals of 0.6 seconds. Cooling fans operate until tempera-
ture returns to normal. Indicator will stop blink, if temperature returns to nor-
mal. Trace the cause of the abnormalities-temperature, and repair the projec-
tor. (Refer to the item of " temperature abnormality" of troubleshooting.)
Y8
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 903~904) are arranged near the two lamps.
Temperature switches will operate, if temperature reaches 85~90 degrees.
SW904 (Lamp-1)----- It operates at 85 degrees.
SW903 (Lamp-2)----- It operates at 90 degrees.
When temperature switches have operated, lamp ballast units will be shut
down, then a projector will be turned off.
■Note;
(1) Usually temperature monitor-2 will operate when other protection equipment did
not operate with trouble, so it is auxiliary protection equipment. When other pro-
tection equipment is rightly operating, this temperature monitor-2 rarely operates.
If this temperature monitor-2 has operated it is thought fault of other protection
equipment. (Refer to the item of " temperature abnormality" of troubleshoot-
ing.)
(2) The CPU does not check operation of temperature switches. Therefore, when
temperature switches have operated and a projector has shut down, TEMPERA-
TURE-WARNING indicator does not blink.

LAMP REPLACEMENT
Before Replacement
This Projector is equipped with 2 Projection Lamps to ensure brighter image and those lamps are controlled by Lamp
Management Function. Lamp Management Function detects status of two 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.
Lamp Status Display
Lamp Status Display appears on screen when power switch is on or changed input position (input 1, input 2 or input 3). This
shows status of each lamp as; ON, OFF, NEAR END, or OUT. Refer to following for each status.
Projection Lamp lights normally.
Lamp Replace Indicator
This LAMP REPLACE indicator lights yellow when any of Projection Lamps is nearing its end, and flashes when any of them
becomes out. Check number of lamp on Lamp Status Display and replace lamp.

Caution: Don't remove three panels simultaneously.
Convergence adjusting becomes impossible when three panels are
removed simultaneously. When three panels simultaneous replace-
ment is required, replace "LCD panel /prism assembly."
Caution :
(1) Do not hit the LCD panel part by screwdriver when
removing screws. Adjustment may be out of place by
shock.
(2) Never touch the LCD panel and prism part directly with
hand. Otherwise the optical parts may get dirty.
(3) Since the LCD panel is equipped with CMOS-LSI, pay
attention to static electricity. And never touch the elec-
trode of flexible cables.
