SAFETY PRECAUTIONS
NOTICE : Comply with all cautions and safety related notes
located on or inside the cabinet and on the chassis.
The following precautions should be observed :
1. When service is required, even though the PDP UNIT an
isolation transformer should be inserted between the power line
and the set in safety before any service is performed.
D
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 resistorcapacitor, 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 manufacture'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.
E
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
manufacture has become defective, or inadvertently defeated
during servicing. Therefore, the following checks should be
performed for the continued protection of the customer and
servicetechnician.
6. Perform the following precautions against unwanted radiation
and rise in internal temperature.
• Always return the internal wiring to the original styling.
• Attach parts (Gascket, Ferrite Core, Ground, Rear Cover,
Shield Case etc.) surely after disassembly.
7. Perform the following precautions for the PDP panel.
• When the front case is removed, make sure nothing hits the
panel face, panel corner, and panel edge (so that the glass does
not break).
• Make sure that the panel vent does not break. (Check that the
cover is attached.)
• Handle the FPC connected to the panel carefully.
Twisting or pulling the FPC when connecting it to the
connector will cause it to peel off from the panel.
8. Pay attention to the following.
• Pay extreme caution when the front case and rear panel are
removed because this may cause a high risk of disturbance to
TVs and radios in the surrounding.

Leakage Current Cold Check
With the AC plug removed from an AC power 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 (input/output terminals, screwheads, metal overlays, control
shafts, etc.), 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 4MΩ. The
below 4MΩ resistor value indicate an abnormality which require
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 an AC power source (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 (input/output terminals, screwheads, metal overlays,
control shaft, etc.), 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 1mA.
PRODUCT SAFETY NOTICE
Many electrical and mechanical parts in PIONEER set have
special safety related characteristics. These are often not evident
from visual inspection nor the protection afforded by them
necessarily can be obtained by using replacement components
rated for higher voltage, wattage, etc. Replacement parts which
have these special safety characteristics are identified in this
Service Manual.
Electrical components having such features are identified by
marking with a on the schematics and on the parts list in this
Service Manual.
The use of a substitute replacement component which dose not
have the same safety characteristics as the PIONEER
recommended replacement one, shown in the parts list in this
Service Manual, may create shock, fire or other hazards.
Product Safety is continuously under review and new instructions
are issued from time to time. For the latest information, always
consult the current PIONEER Service Manual. A subscription to,
or additional copies of, PIONEER Service Manual may be
obtained at a nominal charge from PIONEER.

NOTES:
Parts marked by "NSP" are generally unavailable because they are not in our Master Spare Parts List.
The mark found on some component parts indicates the importance of the safety factor of the part.
Therefore, when replacing, be sure to use parts of identical designation.
When ordering resistors, first convert resistance values into code form as shown in the following examples.
Ex.1 When there are 2 effective digits (any digit apart from 0), such as 560 ohm and 47k ohm (tolerance is shown by J=5%,
and K=10%).
