it is returned to the customer.
1 SAFETY PRECAUTIONS
1.1.
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.
Figure 1
6. After servicing, be sure to restore the wires, leads,
insulation barriers, shields, etc.
1.4.
7. After servicing, make the leakage current checks to prevent
the customer from being exposed to shock hazards.
UV-PRECAUTION
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.
3. The lamp emits small amounts of UV-Radiation.
1.2.
Avoid direct-eye contact by covering the Lamp and wearing
the UV protective glasses.
LEAKAGE CURRENT COLD
CHECK
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 reading should be between 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.
Figure 2
LEAKAGE CURRENT HOT
CHECK
1. Plug the AC cord directly into the AC outlet.
Do not use an isolation transformer for this check.
2. Connect "A" to exposed metallic part on the set. And
connect "B" to 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.
1.5.
4. Check each exposed metallic part, and measure the
voltage at each point.
TEMPERATURE DETECTION
FOR THE LAMP UNIT
5. Reverse the AC plug in the AC outlet and repeat each of the
above measurements.
This projector has bimetal (Thermostat) contacting the lamp
unit to protect the lamp. If the temperature of the lamp exceeds
120 °C, the bimetal will operate to turn off the power.
6. The potential at any point should not exceed 0.25 V RMS.
The installed position of the bimetal is shown in the illustration.
A leakage current tester (Simpson Model 228 equivalent)
may be used to make the hot checks. Leakage current must
not exceed 1/2 mA. In case a measurement is outside of
the limits specified, there is a possibility of shock hazard,
To recover the bimetal from its off state, press the protrusion of
the bimetal unit until hear click.

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).
Figure 3
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,whichshould be 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)sufficientto damage an ES device).
