■ Safety Instructions
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.
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 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.

service personnel must be sure it is completely safe to
operate without danger of electric shock.
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.
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.

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 operating 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. Tu rn the power off, and disconnect the AC power cord
from the AC outlet.
2. Tu rn 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”.

● Service Adjustment Menu Operation
IC808 on the main board stores the data for the service adjustments, and should not be replaced except for
the case of defective device.
If replaced, the re-adjustments are required following to
the “Electrical Adjustments”.
The data of lamp replacement counter is stored in the
IC808.
Please note that the lamp replace counter will be reset
when the memory IC (IC808) is replaced.
(Lamp replace counter can not be set to the previous
value.)
● Caution to memory IC replacement
When IC808 is replaced with new one, the CPU writes
down the default data of the service adjustments to the
replaced IC as the mentioned on the service adjustment table. As these data are not the same data as factory shipped data, it should be required to perform the
re-adjustments following to the “Electrical Adjustments”.
Please note that in this case the lamp replace counter
will be reset.
● Caution of Main Board replacement (in the case
IC808 is not defective)
When the main board is replaced, IC808 should be
replaced with the one on previous main board. After
replacement, it should be required to perform the readjustments following to the “Electrical Adjustments”.

The possible causes of No Power are listed below. Please
check following and refer to the chapter “Power supply and
protection circuit” in the Chassis Block Diagrams on the previous page.
1. It does not operate the power supply circuit due
to detection of abnormality.
- The abnormality on the secondary power supply lines was
detected.
One of the power failure detection diodes detects an
abnormal voltage on the power supply. Check the shortage of secondary circuits, ICs, condensers, etc.
Check power supply lines, FAN1, 16V, 14,5V and
15AUDIO on the Audio Board, and 5V, 5VD, 15.5V, 3.3V,
15VP, 9V, 5V1, 5V_DV, 2.5V1, 12V, 3.3_AV, 3.3V_AD1,
3.3V_AD2, 3.3V_AD3, 2.5V1 and 12V on the Main
Board.

And this signal drives Q4891 on and the P-FAIL signal
becomes low.
- The abnormal temperature rise inside the projector was
detected.
Temperature sensor ICs detect abnormal temperature.
Check peripheral circuits and sensor ICs IC2821 on the
Sensor Board, IC1871 , IC1872 and IC1873 on the Main
Board.
Thermal switch (SW905) detects abnormal temperature.
Check peripheral circuits and SW905.
SW905...................... short in normal
SW905 opens when peripheral temperature is over 90°C.
- The abnormality on the lamp ballast board was detected.
The lamp ballast board outputs error signal (LAMP_DET)
to pin 123 of IC801.
LAMP_DET .............. High in abnormal
- The Interlock switch (SW902) is not turned on.
Check lamp cover fixed correctly.
- Fuse was opened.
Check the fuse on the Line Filter Board.
2. Abnormality occurs on drive signals f
or power
or lamp circuit.
- Abnormality on power starter signals (FAN_DRIVE/
FAN_SW).
The FAN_SW signal is output from pin 137 of IC801 and
applied to power supply circuit through Q4807 as the
name of FAN_DRIVE. It drives the fans on and off.
FAN_DRIVE .................. High in power on
Check FAN_DRIVE signal, IC801 and peripheral circuits.
- Abnormality on the drive signal (IC_RESET).
The IC_RESET signal is output from pin 2 of IC801 and
sent to the power DC board to switch the power on and
off.
IC_RESETHigh in power on
Check IC_RESET signal, IC801 and peripheral circuits.
- Abnormality on the lamp drive signal (LAMP_SW).
The LAMP_SW signal is output from pin 138 of IC801
and sent to IC4891. IC4891 also receives the P-FAIL signal and outputs the drive signal to pin 4 of K8L and the
lamp ballast board.
LAMP_SW ................ High in power on
Check LAMP_SW signal, IC801 and peripheral circuits.
3. Abnormality occurs on the power circuit.
- Abnormality on power primary circuit
Check Line filters, thermal switch (SW905), interlock
switch (SW902) the Power AC board and Power DC
board.
About the LED indicator flashing
The projector will be automatically turned off when the internal temperature of the projector exceeds the normal operating 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 air filters and remove the object near the intake
and exhaust fan openings, 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.
Reset switch
The projector does not allow any controls rarely when the
abnormality of power or operation occurs inside the projector. In this case, press the reset switch on the rear panel to
restart the projector.

■ Cleaning
Cleaning with air spray
1. Remove the cabinet top following to “Mechanical
Disassemblies”.
2. Clean up the LCD panel and polarizing plate by using
the air spray from the cabinet top opening.
Caution:
Use a commercial (inert gas) air spray designed for
cleaning camera and computer equipment. Use a resinbased nozzle only. Be vary careful not to damage optical parts with the nozzle tip. Never use any kind of
cleanser on the unit. Also, never use abrasive materials
on the unit as this may cause irreparable damage.
After long periods of use, dust and other particles will accumulate on the LCD panel, prism, mirror, polarized glass,
lens, etc., causing the picture to darken or color to blur. If this occurs, clean the inside of optical unit.
Remove dust and other particles using air spray. If dirt cannot be removed by air spray, disassemble and clean
the optical unit.
Disassembly Cleaning
Disassembly cleaning method should only be performed when the unit is considerable dirty and cannot
be sufficiently cleaned by air spraying alone.
Be sure to readjust the optical system after performing disassembly cleaning.
1. Remove the cabinet top and main units following to
“Mechanical Disassemblies”.
2. Remove the optical base top following to “Optical Unit
Disassemblies”. If the LCD panel needs cleaning,
remove the LCD panel unit following to “LCD panel
replacement”.
3. Clean the optical parts with a soft cloth. Clean
extremely dirty areas using a cloth moistened with
alcohol.
Caution:
The surface of the optical components consists of multiple dielectric layers with varying degrees of refraction.
Never use organic solvents (thinner, etc.) or any kind of
cleanser on these components.
Since the LCD panel is equipped with an electronic circuit, never use any liquids (water, etc.) to clean the unit.
Use of liquid may cause the unit to malfunction.
