1 Safety Precautions
1.1. General Guidelines
· For continued safety, no modification of any circuit must be
attempted.
· Unplug the power cord from the power outlet before
disassembling this projector.
· Use correctly the supplied power cord and must ground it.
· It is advisable to use an isolation transformer in the AC
power line before the service.
· Be careful not to touch the rotation part (cooling fan, etc.) of
this projector when you service with the upper case
removed and the power supply turned ON.
· Observe the original lead dress during the service. If a short
circuit is found, replace all the parts overheated or
damaged by the short circuit.
· After the service, all the protective devices such as
insulation barriers, insulation papers, shields, and isolation
R-C combinations must be properly installed.
· After the service, check the leakage current to prevent the
customer from getting an electric shock.
1.2. Leakage Current Check
1.Prepare the measuring circuit as shown in Fig.1.
Be sure to use a voltmeter having the performance
described in Table 1.
Fig. 1
Table 1
Fig. 2
2.Assemble the circuit as shown in Fig. 2. Plug the power
cord in a power outlet.
3.Connect M1 to T1 according to Fig. 2 and measure the
voltage.
4.Change the connection of M1 from T1 to T2 and measure
the voltage again.
5.The voltmeter must read 0.375 V or lower in both of steps
3 and 4. This means that the current must be 0.75 mA or
less.
6.If the reading is out of the above standard, the projector
must be repaired and rechecked before returning to the
customer because of a possibility of an electric shock.
1.3. UV Precaution and UHM Lamp
Precautions
· Be sure to unplug the power cord from the power outlet
when replacing the lamp.
· Because the lamp reaches a very high temperature during
its operation, wait until it cools completely when replacing
the Lamp Unit.
· The lamp emits small amounts of UV-radiation, avoid direct-
eye contact with the light.
· The lamp unit has high internal pressure. If improperly
handled, explosion might result.
· Because the high pressure lamp involves a risk of failure,
never touch the lamp wire lead during the service. (See Fig.
3)

2 Ext Option
This projector has EXT OPTION in addition to standard on-screen menus.
· There are SELF CHECK and FLICKER ADJUST for service, etc.
2.1. Procedure to enter EXT OPTION
1.When the projector is power ON, press "POWER" button on the main unit or remote control unit to display "POWER OFF"
confirmation screen.
2.Press the right-arrow " " button to select "CANCEL" in the "POWER OFF" confirmation screen.
3.On the main unit or remote control unit, press the buttons in order of up-arrow " ", down-arrow " ", up-arrow " ",
down-arrow " " and "ENTER".
(When the "ENTER" button is pressed, "EXT OPTION" menu is displayed.)
2.2. EXT OPTION Menu and Functions
· FAN FULLMODE
Setting the cooling fan motor rotation speed
− − −
− Switching ON "FAN FULLMODE", the rotation level of the fan becomes high-speed rotation (fixed). Moreover, when "FAN
FULLMODE" is ON, changing "ALTITUDE" in OPTION becomes impossible (setting FAN FULLMODE is given priority more
than ALTITUDE).
· AUTO SETUP
Setting AUTO SETUP mode
− − −
− NORMAL: To set the normal mode (the dot clock is adjusted strictly)
− − −
− SPECIAL: To set the special mode (the dot clock is adjusted roughly)
* Do not change the initial setting (NORMAL).
· SELF CHECK
To enter the self-check mode
· FLICKER ADJUST
To enter the flicker adjustment mode
· 525i SD
When non-standard signal of 525i/625i is inputted (AV amplifier, etc.), synchronization might be disordered according to
connected equipment. In this case, set 525i SD to ON.
· OS
When a component signal (except 525i, 625i, 1125/60p and 1125/50p) is inputted, reflection noise (vertical striated beat) might
be generated according to connected equipment. In this case, set OS to ON. However, the resolution decreases a little.
· HPLL
When non-standard signal of VIDEO/S-VIDEO is inputted (VTR, VHD, etc.), horizontal synchronization might be disordered
according to connected equipment. In this case, set HPLL to OFF.
2.3. Canceling EXT OPTION
Press "MENU" button on the main unit or remote control unit.

6 Disassembly Instructions
Warning:
· Be sure to unplug the power cord from the power outlet before disassembling this projector.
Caution:
· While turning over a printed circuit board, be sure to put a insulating material under it to prevent a short circuit.
· Printed circuit boards and wires must not be pulled forcibly, but be handled carefully.
· Connectors also must be handled carefully.
· When reassembling, replace used adhesive tape with new one (Do not re-use used tape).
· After repairing this projector, be sure to put back the wires and connectors to the original condition.
· Service or repair the product according to service information on the service manual, etc. so that a fire, injury or electric
shock caused by an improper repair may not occur.
1.Do not modify equipments, components and materials when attempting to service or repair.
2.Do not repair nor connect wires even in case of a part of the disconnection when the wiring unit is supplied as a
replacement parts, replace the wiring unit (complete).
3.For a fasten terminal (push-in type terminal), pull out or insert straightly without twisting it.
