1.1 SAFETY PRECAUTIONS
(FOR USA MODEL ONLY)
NOTICE : Comply with all cautions and safety related notes located
on or inside the cabinet and on the chassis or mirror case.
The following precautions should be observed:
1. When service is required, even though the FRONT PROJECTOR
an isolation transformer should be inserted between power line
and the set in safety before any service is performed.
2. When replacing a chassis in the set, all the protective devices
must be put back in place, such as barriers, nonmetallic knobs,
adjustment and compartment covershields, isolation resistor-
capacitor, etc.
3. When service is required, observe the original lead dress.
Extra precaution should be taken to assure correct lead dress in
the high voltage circuitry area.
4. Always use the manufacturer's replacement components.
Especially critical components as indicated on the circuit diagram
should not be replaced by other manufacture's.
Furthermore where a short circuit has occurred, replace those
components that indicate evidence of overheating.
5. Before returning a serviced set to the customer, the service
technician must thoroughly test the unit to be certain that it is
completely safe to operate without danger of electrical shock,
and be sure that no protective device built into the set by the
manufacturer has become defective, or inadvertently defeated
during servicing.
Therefore, the following checks should be performed for the
continued protection of the customer and service technician.
Leakage Current Cold Check
With the AC plug removed from the l20V AC 60Hz source, place a
jumper across the two plug prongs. Turn the AC power switch on.
Using an insulation tester (DC 500V), connect one lead to the
jumpered AC plug and touch the other lead to each exposed metal
part (screwheads on the rear), particularly any exposed metal part
having a return path to the chassis. Exposed metal parts having a
return path to the chassis should have a minimum resistor reading
of 0.3M
and a maximum resistor reading of 5M. Any resistor
value below or above this range indicates an abnormality which
requires corrective action. Exposed metal parts not having a return
path to the chassis will indicate an open circuit.
Leakage Current Hot Check
Plug the AC line cord directly into a 120V AC 60Hz outlet (do not
use an isolation transformer for this check). Turn the AC power
switch on.
Using a "Leakage Current Tester (Simpson Model 229 equivalent)",
measure for current from all exposed metal parts of the cabinet
(screwheads on the rear), particularly any exposed metal part having
a return path to the chassis, to a known earth ground (water pipe,
conduit, etc.). Any current measured must not exceed 0.5mA.
ANY MEASUREMENTS NOT WITHIN THE LIMITS
OUTLINED ABOVE ARE INDICATIVE OF A
POTENTIAL SHOCK HAZARD AND MUST BE
CORRECTED BEFORE RETURNING THE SET TO
THE CUSTOMER.
1. SAFETY INFORMATION
This service manual is intended for qualified service technicians ; it is not meant for the casual do-it-
yourselfer. Qualified technicians have the necessary test equipment and tools, and have been trained
to properly and safely repair complex products such as those covered by this manual.
Improperly performed repairs can adversely affect the safety and reliability of the product and may
void the warranty. If you are not qualified to perform the repair of this product properly and safely, you
should not risk trying to do so and refer the repair to a qualified service technician.
