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.
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 pro-
vided 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 PROTE
CTIVE SHIELD IN POSITION AND PROPERLY 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.
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 spe-
cial 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 gener-
ates high voltages(15kV - 20kV) 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.

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.
● 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 this 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.

Panel Type Check
There are 2 types combination of the LCD Panel/Prism Ass'y and the optical unit, named Type-L and Type-R.Since both have no
compatibility, each type should be combined with the same type, and the specificparts should be used. If not, the poor optical
characteristics may degrade the quality of a projected image.
When replacing the LCD Panel/Prism Ass'y,you need to take "Panel Type Check and Setting" on the Electrical Adjustment.
The gamma-characteristics is different between Type-L and Type-R LCD Panel/Prism Ass'y

● Description of System control circuit
Remote control
R/C signal is sent to pin 292 of IC301(Main CPU) and also sent to pin 20 of IC4801(Sub CPU).
Thermal switch
There is the thermal switch (SW902) above the lamp holder to prevent the internal abnormal temperature rising. If the
internal temperature reaches near 100°C, the switch will be opened and the lamp operation will be stopped.
Remark;
The thermal switch is not reset to normal automatically even if the internal temperature becomes normal, so in
this case you have to reset it manually.
Lamp cover switch
If the lamp cover is not fixed securely, the lamp cover switch(SW8803) will be open, and LAMP_SW signal will be shut off
automatically and the lamp operation will be stopped.
Temperature sensor
The projector provides the temperature sensors "TH901", "TH902" and "IC8841" to prevent the internal temperature rising
abnormally and to control the cooling fans. (refer to "Fan control circuit" for detail)
If the internal temperature rising abnormally over the threshold value, the IC301 shuts down after cooling.
Service port
The mini DIN-8 pin jack is used for service the projector with RS-232C. The RS-232C Rx/Tx signals are connected to pins
291and 386 of IC301 via IC3801(RS-232C RECEIVER/DRIVER). The main program and data are stored in IC801(FLASH ROM).
The program can be replaced with new one by specified software "FlashUpgrader".

● Description of Fan control circuit
Fan control circuit
The Fan drive power supplies "FAN1", "FAN2", "FAN3", "FAN4" and "FAN5" are generated from "S16V_F". Each power supply
drives fans as follow;
FAN1 ........FN901 for power and ballast exhaust
FAN2 ........FN902 for lamp cooling
FAN3 ........FN903 for lamp exhaust
FAN4 ........FN904 for intake and panel cooling
FAN5 ........FN905 for intake and panel cooling
The fan spinning speed is controlled by "FAN_CONT0", "FAN_CONT1", "FAN_CONT2" and "FAN_CONT3" from pins 65,176,66
and 177 of IC301.
Power failure protection of Fan
The alarm output signals(PWM signals) from the fans are connected to IC4401(Color Manager) and IC4401 monitors the fan
spinning speed for safety.
When an abnormality occurs on any one of the fans, for example the fan spinning speed is lower than the specified speed,
IC301 shuts down the projector. If a fan connector is not connected firmly, IC301 also shuts down the projector.
Temperature sensor for Fan control
TempA - TH902 around the intake fan "FN904"and "FN905" for outer temperature of the projector
TempB - IC8841(side the lamp) on the Main board for optical parts
TempC - TH901 on the polarized glass (IN-B) for panel and polarized glass temperature
The temperature sensors measure surrounding temperature and sends data to IC301. IC301 controls the proper fan spin-
ning speed based upon these temperature data. Also, when a temperature rises over a specified value, IC301 judges that
there is abnormal internal temperature and turns off the projector.
Temperature vs Fan spinning speed
The fan spinning speed is controlled with
the temperature and the lamp power.

● Description of Power supply circuit
When the projector is standby mode, IC301(Main CPU) is not working and IC4801(Sub CPU) is only working for saving ener-
gy.
When the projector is connected to outlet with AC power cord and the Mains SW is switched to ON, SS3.3V line is supplied
to to standby circuit, including IC4801. IC4801 is waiting for the POWER ON/STAND-BY key input or remote control signal.
When the projector is turned on, "POWER_ON SW" signal (Power ON:H) is sent to the UNIT_POWER, and then the switching
power supply circuit starts operation. "MAINON_SW" signal (Lamp ON:H) from pin 25 of IC301 is also sent to UNIT_POWER,
and then the lamp power supply circuit starts operation.
The "1.8V_SW", "3.3V_SW", "15V_SW" and "FAN_SW" signals are also sent to the power supply circuits.
Power failure protection of secondary power circuit
The projector provides a protection circuit to prevent the secondary failure when the power failure, fans failure or tempera-
ture failure occurs on the projector. The power failure detection lines are connected to the main power supplies. When a
failure occurs, IC301 receives the power failure detection signals "POWER_FAIL" through the power failure detection lines
and "MAINON_SW" signal (Lamp OFF:L) and "POWER_ON SW" signal (Power OFF:L) are supplied to the UNIT_POWER to
stop the power supply operation, and the lamp operation is stopped with "LAMP_SW" signal (Lamp OFF:H).
