1.1.
not exceed 1/2 mA. In case a measurement is outside of
the limits specified, there is a possibility of shock hazard,
and thereceivershouldbe repaired and rechecked before it
is returned to the customer.
GENERAL GUIDELINES
1. For continued safety, no modification of any circuit should
be attempted.
2. Disconnect AC Plug before disassembling this unit.
3. It is advisable to use an isolation transformer in the AC
supply before servicing.
4. When servicing, observe the original lead dress. If a short
circuit is found, replace all parts which have been
overheated or damaged by the short circuit.
5. After servicing, see to it that all the protective devices such
as insulation barriers, insulation papers, shield, and
isolation R-C combinations etc. are properly installed.
6. After servicing, be sure to restore the wires, leads,
insulation barriers, shields, etc.
Figure 1
7. After servicing, make the leakage current checks to prevent
the customer from being exposed to shock hazards.
1.4.
1. Be sure to disconnect the AC Plug when replacing the
lamp.
Caution:
2. Since the lamp reaches a very high temperature during its
operation, wait until it has completely cooled off when
replacing the Lamp Unit.
Use a separate Isolation Transformer for this unit when
servicing.
1.2.
UV-PRECAUTION
3. The lamp emits small amounts of UV-Radiation.
LEAKAGE CURRENT COLD
CHECK
Avoid direct-eye contact by covering the Lamp and wearing
the UV cut protective glass.
4. The high pressure lamp involves a risk of explosion.
1. Unplug the AC cord and connect a jumper between the two
prongs on the plug.
2. For physically operated power switches, turn power on.
Otherwise skip step 2.
3. Measure the resistance value, with an ohmmeter, between
the jumpered AC plug and each exposed metallic cabinet
part on the receiver, such as screwheads, connectors, etc.
When the exposed metallic part has a return path to the
chassis, the readingshouldbebetween 1 MΩ and 12 MΩ.
When the exposed metal does not have a return path to the
chassis, the reading must be infinity.
1.3.
LEAKAGE CURRENT HOT
CHECK
Figure 2
1. Plug the AC cord directly into the AC outlet.
Do not use a isolation transformer for this check.
2. Connect a 1.5 kΩ, 10 W resistor, in parallel with a 0.15 µF
capacitor, between each exposed metallic part on the set
and a good earth ground, as shown in Figure 1.
3. Use an AC voltmeter, with 1 kΩ/V or more sensitivity, to
measure the potential across the resistor.
4. Check each exposed metallic part, and measure the
voltage at each point.
5. Reverse the AC plug in the AC outlet and repeat each of the
above measurements.
6. The potential at any point should not exceed 0.75 V RMS.
A leakage current tester (Simpson Model 229 equivalent)
may be used to make the hot checks. Leakage current must

2 PREVENTION OF
ELECTROSTATIC
DISCHARGE (ESD) TO
ELECTROSTATICALLY
SENSITIVE (ES) DEVICES
Some semiconductor (solid state) devices can be damaged
easily by static electricity. Such components commonly are
called Electrostatically Sensitive (ES) Devices. Examples of
typical ES devices are integrated circuits and some field-effect
transistorsandsemiconductor"chip" components. The following
techniques should be used to help reduce the incidence of
component damage caused by electro static discharge (ESD).
1. Immediately
before
handling
any
semiconductor
component or semiconductor-equipped assembly, drain off
any ESD on your body by touching a known earth ground.
Alternatively, obtain and wear a commercially available
discharging ESD wrist strap,whichshouldbe removed for
potential shock reasons prior to applying power to the unit
under test.
2. After removing an electrical assembly equipped with ES
devices, place the assembly on a conductive surface such
as aluminum foil, to prevent electrostatic charge buildup or
exposure of the assembly.
3. Use only a grounded-tip soldering iron to solder or unsolder
ES devices.
4. Use only an antistatic solder removal device. Some solder
removal devices not classified as "antistatic (ESD
protected)" can generate electrical charge sufficient to
damage ES devices.
5. Do not use freon-propelled chemicals. These can generate
electrical charges sufficient to damage ES devices.
6. Do not remove a replacement ES device from its protective
package until immediately before you are ready to install it.
(Most replacement ES devices are packaged with leads
electrically shorted together by conductive foam, aluminum
foil or comparableconductivematerial).
7. Immediately before removing the protective material from
the leads of a replacement ES device, touch the protective
material to the chassis or circuit assembly into which the
device will be installed.
CAUTION :
Be sure no power is applied to the chassis or circuit, and
observe all other safety precautions.
8. Minimize bodily motions when handling unpackaged
replacement ES devices. (Otherwise harmless motion such
as the brushing together of your clothes fabric or the lifting
of your foot from a carpeted floor can generate static
electricity (ESD)sufficienttodamage an ES device).

Lamp Replacement Procedure:
REPLACEMENT OF LAMP
1. Press the POWER button on the remote to turn off the
power.
2. Wait for about 1 minute until the cooling fan stops.
Note:
The lamp cooling fan will continue to operate for about 1
minute after the power is turned off. Do not unplug the AC
Cord from the outlet until the fan has stopped. Avoid
interrupting the power by using circuit breakers or switchable
power strips.
3. After the cooling fan has stopped, unplug the AC Cord from
the outlet.
Note:
Please wait more than one hour before replacing the lamp.
[ Forced cooling function ]
If you need to replace the lamp more urgently:
• The Projection display has a forced cooling feature.
After the POWER button is turned OFF, and sometime
during about the first minute of the normal cooling fan
operation, press the VOLUME UP button on the unit
and CH UP key on the remote at the same time for more
than 5 seconds. The cooling fan will operate for about
10 minutes. (LAMP LED will flash 5 times every 5
second and POWER LED will flash red for 10 minutes.)
4. Remove the Front Cover Unit from the latches.
5. Remove the Lamp Cover by loosening the Screw.
Lamp Time Reset Procedure:
Be sure to reset the Lamp time to "0" after replacing the new
Lamp.
1. Plug in the AC Cord, and turn on the power by pressing the
POWER button.
2. Press and hold the VOLUME DOWN button on the unit and
the SPLIT key on the remote together for over 5 seconds in
power on condition.
When the reset is finished, the display as shown in Fig. 51 appears and the LAMP LED goes out.
Fig. 5-1
Note:
1. The unit will detect when the Lamp’s end of life is
approaching and the following message will be
displayed. And the LAMP indicator light will be lit when
the Lamp’s end of life is approaching.
Lamp Cover
Screw
Fig. 5-2
Fig. 5-3
2. Influences of frequent lighting, continuous light use for
over 24 hours, the number of times lit, the length of time
between lightings, etc. may shorten lamp life. (Because
of this, we recommend having a replacement lamp on
hand.)
