Safety Instructions
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.
DO NOT OPERATE THIS PROJECTOR WITHOUT
THE PROTECTIVE SHIELD IN POSITION AND PR
OPERLY SECURED.
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.
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 special 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
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.

Maintenance
Cleaning
After long periods of use, dust and other particles will accumulate on the optical parts, mirror, color wheel, lens etc.,
causing the picture to darken or color to blur. If this occurs, remove dust and other particles using air spray. Before
taking the cleaning, turn off the projector and allow the projector to cool for more than 45 minutes. Never disassemble the optical unit, mirror or projection lens because those parts are aligned preciously in the factory . If do so,
the projector may have the miss-alignment in optical and reduce the optical performance.
Cleaning the Color Wheel
- The color wheel is made of thin glass. Be very careful
when handing the color wheel.
- In case of fingerprints, etc. on the surface, gently wipe
with a Cleaning Cloth for optical parts that contains a
small amount of non-abrasive camera lens cleaner to
clean the surface.
- Do not use detergents as this could cause peeling of
the color filter.
Cleaning the Projection Window
Unplug the AC power cord before cleaning.
First, remove the dust with a commercially available air blower. Then gently wipe the projection window surface. Use a
cleaning paper moistened with methyl alcohol (methanol).
Avoid using an excessive amount of cleaner.
Do not use abrasive cleaners, solvents, or other harsh
chemical cleaners to avoid damaging the projection window.
Cleaning the Reflecting Mirror
- Be careful not to touch the reflecting mirror. Touching
it directly with the hands may cause reducing the burnishing.
- Do not clean other than with air.
Caution:
The optical components may have a crack or spot when
you use the air spray directly to the optical components
while they are in the state of hot. Use a commercial (inert
gas) air spray designed for cleaning camera and computer equipment. Use a resin-based nozzle only. Be very
careful not to damage optical parts with the nozzle tip.
Cleaning the Projector Cabinet
Unplug the AC power cord before cleaning.
Gently wipe the projector body with a soft dry cleaning cloth.
When the cabinet is heavily soiled, use a small amount of
mild detergent and finish with a soft dry cleaning cloth. Avoid
using an excessive amount of cleaner. Abrasive cleaners,
solvents, or other harsh chemicals might scratch the surface of the cabinet.
When the projector is not in use, put the projector in an appropriate carrying case to protect it from dust and scratches.
CAUTION
Do not use any flammable solvents or air sprays on the projector and in its vicinity. The explosion or fire hazard may
occur even after the AC power cord is unplugged because
the temperature inside the projector is extremely high due to
the lamps. In addition, there is a risk that the internal parts
may be damaged not only by the flammable air spray but
also by the cold air.

Troubleshooting
No Power
This projector provides a function which can be specified a defective area simply by indicating the LEDs. Connect the
AC cord and press the Power button once and then check the LED indication.
- When all of LED indicators are not lighting, the symptom indicates that the primary power supply circuit does
not operate properly. Check the power primary circuit and parts as follow;
AC cord, F601 (Fuse), Line Filter board,
SW902 (Thermal sw.) ............... short in normal
SW902 opens when the surrounding temperature of the switch exceeds 120°C.
- When the WARNING TEMP (red) and POWER (red) indicators are blinking, the symptom indicates that the
projector detected an abnormal temperature risen inside the projector. Check the air filter and remove the object
near the intake and exhaust fan openings, and wait until the POWER indicator stops blinking, and then try to turn
on the projector.
The internal temperature is monitored by sensor ICs, IC8801 on the Temp Sensor 1 board, IC8811 on the Temp
Sensor 2 board, IC8821 on the Main board.
- When the WARNING TEMP indicator lights red, the symptom indicates that the projector detected an abnor-
mality in the cooling fan operation or in the power supply secondary circuits. Check fan operation and power supply lines, and the driving signal status.
The PFAIL signal (Error: H) is sent to pin 143 of IC401<DLP DATA PROCESSOR> when the abnormality oc-
curred inside the projector, and then the IC401 sends the shutdown signal, LAMPDC_ON, to the power supply
circuit to stop its operation, and signal LAMPSYNC is supplied to the lamp ballast board via SW901<lamp cover
switch> to stop operation of the lamp circuit. The LAMPSYNC signal is output from pin 98 of IC401 as the name
of LAMPCTRL signal.
An abnormality occurs on the secondary power supply;
Check power supplies 12V, S-5V, 16VF, 16VA. The PFAIL signal becomes “High” when the abnormality occurs
on any of the power supply lines.
An abnormality occurs on the fan control circuit;
Check FN901, FN902, FN903, FN904, FN905, FN906 and 16VF and peripheral circuit.
If any of the fans has an error, the fan lock signal drives Q7891 becomes "High". As the result, signal PFAIL_
FAN becomes Low. This error signal is supplied to the P-Fail logic ICs and it is finally supplied to the pin 143 of
IC401 as the PFAIL signal.
An abnormality occurs on the drive signals;
PWR_SW_LAN signal (Power-on: H) is output from pin 39 of IC401 to switch Q8372, 3.3V_LAN supply cir-
cuit. PWR_CTRL signal (Power-on: H) is output from pin 45 to switch Q1482, P1P2V_EDRAM supply circuit.
AUDIO_12V_SW signal (Poweron:H) is output from pin 310 to switch Q5101, 12V_AUDIO supply circuit. AUDIO_PWR_ON signal (Power-on:H) is output from pin 378 to switch Q5661, 16VA supply circuit.
POWER_SW_B signal (Power-on:H) is output from pin 14 of IC4501 to drive IC5631 (12V, S-5V) and
Q5651(16VF).
LAMPDC_ON signal (Power-on: H) is output from pin 305 of IC401 to drive the PFC circuit , IC621, on the power
supply board through PC661.
LAMPSTAT signal at the pin 276 of IC401 is applied from the lamp ballast unit. If the abnormality occurred on
the lamp ballast unit, LAMPSTAT signal becomes “High” and then IC401 shuts down the power supply circuit.
Lamp Cover switch
Make sure that the lamp cover is mounted correctly.
If not or the lamp cover removed, the lamp does
not light on for the safety. Check the lamp cover and
lamp cover switch (SW901).

Note on Soldering
Do not use solder containing lead.
This product has been manufactured using lead-free
solder in order to help preserve the environment.
Because of this, be sure to u s e lead-free solder
when carrying out repair work, and never use solder
containing lead.
Lead-free solder has a melting point that is 30–40 °C
(86–104 °F) higher than solder containing lead, and
moreover it does not contain lead which attaches easily
to other metals. As a result, it does not melt as easily
as solder containing lead, and soldering will be more
difficult even if the temperature of the soldering iron is
increased.
The extra difficulty in soldering means that soldering
time will increase and damage to the components or
the circuit board may easily occur.
Be cause of this, you should use a soldering iron
and solder that satisfy the following conditions when
carrying out repair work. Also, soldering work must be
done in a short time.
Solder
Use solder with the metal content and composition ratio
by weight given in the table below. Do not use solders
which do not meet these conditions.
Metal contentTin (Sn)Silver (Ag)Copper (Cu)
Composition
ratio by weight
Note:
If replacing existing solder containing lead with leadfree solder in the soldered parts of products that have
been manufactured up until now, remove all of the
existing solder at those parts before applying the leadfree solder.
96.5 %3.0 %0.5 %
Soldering iron
Use a soldering iron which is 70 W or equivalent, and
which lets you adjust the tip temperature up to 450
°C (842 °F) It should also have as good temperature
recovery characteristics as possible.

Components indicated by a mark ! in this schematic diagram have
the special significance in the safety. It is therefore, particularly rec
ommended that the replacement of those parts must be made by
exactly the same parts. Must be used with a specified fuse. Unau
thorized substitutions may result in fire or accident.
This projector is isolated from AC line by using the internal converter
transformer. Please pay attention to the following notes in servicing.
1. Do not touch the part on hot side (primary circuit) or both parts on
the hot and cold sides (secondary circuit) at the same time.
2. Do not shorten the circuit between hot and cold sides.
3. The grounding lead must be connected to the ground of the same
circuit when measuring the voltages and waveform.
