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.) ......
SW902 opens when the surrounding temperature of the switch exceeds 105°C.
- When the WARNING (red) and POWER (red) indicators are flashing, the symptom indicates that the projector 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, IC8801, IC8821 and IC8831 on the Main 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 382 of IC301<SYSTEM CONTROL> when the abnormality occurred inside the
projector, and then the IC301 sends the shut down signals, DC_ON and LAMPDC_ON, to the power supply circuit to stop
its operation, and signal BALAST_AC to the lamp ballast board via IC4891 and SW901<lamp cover switch> to stop opera-
tion of the lamp circuit.
An abnormality occurs on the secondary power supply;
Check power supplies 15.5V, S15.5V, S6V, S-5V. 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 on. 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;
DC_ON signal (Power-on: H) is output from pin 72 of IC301 and supplied to power supply circuit.
LAMPDC_ON signal (Power-on: H) is output from pin 73 of IC301 and supplied to the P.F Control IC, IC621, on the
power supply board through Q651, and PC643.
PWM_20HZ signal (Power-on: H) is output from pin 71 of IC301 and applied to pin 2 of IC4891 and output pin 4 and
then supplied to the lamp ballast board through the Lamp Cover switch (SW901).
CHO_RXD signal at the pin 140 of IC301 is applied from the lamp ballast unit. If the abnormality occurred on the lamp
ballast unit, CHO_RXD 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).
Reset switch
The microprocessor inside the projector may occasionally
malfunction and does not accept any controls. In this case,
press the reset switch on the rear panel with a sharp tool
to restart the projector.

Cleaning
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.
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.

Note on Sordering
KZ6-XL4500
Do not use solder containing lead.
This product has been manufactured using lead-free
solder in order to help preserve the environment.
Becaus e of thi s, be sure to u se lead-free so lder
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 cau se of this, you should use a s old eri ng 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
96.5 %3.0 %0.5 %
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.
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.

Schematic Diagrams
CAUTION
Fuse of the specified parts number
must be used.
Unauthorized substitutions may result
in fire or accident.
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.
