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.
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, adjust-
ment covers or shields, barriers, etc.
DO NOT OPERATE THIS PROJECTOR WITHOUT T
HE PROTECTIVE SHIELD IN POSITION AND PROP
ERLY 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 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.

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), Power board,
SW902 (Thermal sw.) short in normal
SW902 opens when the surrounding temperature of the switch exceeds 100°C.
- When the WARNING (red) and POWER (red) indicators are flashing, the symptom indicates that the projec-
tor detected an abnormal temperature risen inside the projector. Check the air filters and remove the object near
the intake and exhaust fan openings, and wait until the POWER indicator stops flashing, and then try to turn on
the projector.
The internal temperature is monitored by sensor ICs, IC8831, IC8821 on the Main board and IC8811 on the
R/C board.
- When the WARNING indicator lights red, the symptom indicates that the projector detected an abnormality 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 P_FAIL signal (Error: L) is sent to pin 215 of IC301<SYSTEM CONTROL> when the abnormality occurred
inside the projector, and then the IC301 sends the shutdown signal, LAMP_DC_ON, to the power supply circuit
to stop its operation, and signal BLAST_AC to the lamp ballast board via IC4891 and SW901<lamp cover switch>
to stop operation of the lamp circuit.
An abnormality occurs on the secondary power supply;
Check power supplies S16V, S6V, S-7V. P_FAIL signal becomes “Low” 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 peripheral circuit.
If any of the fans has an error, the fan lock signal drives Q3601 becomes "High". As the result, signal
FAN_ERR becomes Low and is sent to lamp ballast board to stop lamp circuit.
An abnormality occurs on the drive signals;
ON_15V signal (Power-on: H) is output from pin 201 of IC301 and switches IC592,15.5VL supply circuit,
ON_5V signal (Power-on: H) is output from pin 110 of IC301 and switches IC5542,IC5081, 11-AMP supply
circuit, ON_3.3V signal (Power-on: H) is output from pin 11 of IC301 and switches IC5621, 1.0V and Q3582
3.3V supply circuit.
LAMP_DC_ON signal (Power-on: H) is output from pin 89 of IC301 and supplied to the P.C Control IC,
IC621, on the power supply board through Q651, and PC661.
BLAST_AC signal (Power-on: H) is output from pin 284 of IC301 and applied to pin 2 of IC4891 and output
pin 4 and then supplied to the lamp ballast board through SW901<Lamp Cover SW>.
LAMP_DET signal at the pin 285 of IC301 is applied from the lamp ballast unit. If the abnormality occurred
on the lamp ballast unit, LAMP_DET signal becomes “High” and then IC301 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).

Schematic Diagrams
CAUTION
Fuse of the specified parts number must be used.
Unauthorized substitutions may
result in fire or accident.
CAUTION
Components indicated by a mark ! in this schematic diagram have
the special significance in the safety. It is therefore, particularly recommended that the replacement of those parts must be made by exactly
the same parts.Must be used with a specified fuse. Unauthorized 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.
