Health & Safety Code Section 25249.6 – Proposition 65
NOTICE
(FOR CANADIAN MODEL ONLY)
Fuse symbols (fast operating fuse) and/or (slow operating fuse) on PCB indicate that replacement parts
must be of identical designation.
REMARQUE
(POUR MODÈLE CANADIEN SEULEMENT)
Les symboles de fusible (fusible de type rapide) et/ou (fusible de type lent) sur CCI indiquent que les
pièces de remplacement doivent avoir la même désignation.
1.1 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.
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.
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
service technician.
6. Perform the following precautions against unwanted radiation
and rise in internal temperature.
• Always return the internal wiring to the original styling.
• Attach parts (Ground, Rear Cover, Shield Case) 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.
• Be sure to wire the fan. If the fan does not work, the temperature
will rise and cause the protection circuit to operate.
• When the front case is removed, infrared ray is radiated and
may disturb reception of the remote control unit.
• 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 0.3MW and a
maximum resistor reading of 5MW. 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.

Page 3
PDP-502MX, PDP-502MXE
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 0.5mA.
Reading should
not be above
0.5 mA

1.2 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
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.
on the schematics and on the parts list in this Service
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.

1.3 CHARGED SECTION AND HIGH VOLTAGE GENERATING POINT
7 Charged Section
The places where the commercial AC power is used without
passing through the power supply transformer.
If the places are touched, there is a risk of electric shock. In addition,
the measuring equipment can be damaged if it is connected to the
GND of the charged section and the GND of the non-charged
section while connecting the set directly to the commercial AC
power supply. Therefore, be sure to connect the set via an insulated
transformer and supply the current.

Diagnosis when under voltage is detected at V SUS / V ADR voltage lines.
Disconnect connector CN205 P5 at Main Power Assy and turn on the power.
If the power is turned on and D205 at Main Power Assy lights up in yellow, cause of the under voltage is not inside Main Power Assy.
If P.D. occurs, V SUS / V ADR DC-DC Converter block at Main Power Assy may be defective.
Diagnosis when under voltage is detected at 14V, 12V, +-8V voltage lines
Be sure to turn off High Power CUT SW, S301 at Power Supply Assy. (important)
Disconnect CN306 P6,CN355 P4, CN354 P3, CN353 P2 at Main Power Assy one by one, and turn on the power of the unit.
(Do not disconnect all four connectors at the same time and turn on the power. Because this leads to no load of power supply and that is
very dangerous.)
When the power is turned on with a connector disconnected, and if Low power supply DC-DC Converter operates normally with lighting
D355 and D205 in red, cause of under voltage is not inside Main Power Assy.
If P.D. still occurs after disconnecting each connector, 14V DC-DC Converter block at Main Power Assy may be defective.
The function of High Power CUT SW, S301 at Main Power Assy
When S301 is turned off, V SUS / V ADR DC-DC Converter does not operate. However, 14V DC-DC Converter operates normally.
Therefore, diagnosis from Signal Input circuit to before Drive circuit is possible without danger of breaking Drive section by mistake.
AC100V/AC200V Change-over SW, S111 at Main Power Assy
Only PDP-502MXE is set to AC200V.
When the SW is set to AC100V, AC200V P.D. detecting circuit will operate. (Even when the unit is in Stand-by mode, the detecting circuit
is in operation.)

PDP-502MX, PDP-502MXE
Note for repairing in case of blown fuses
Never turn on the power of the unit again just by replacing the fuse, when the fuse is blown.
Because, it is rare case that the fuse itself is defective. If the power is turned on again without resolving the cause of over
current, the unit is damaged more.
Be sure to check parts such as In-Rush current protective resistors where excessive current may flow.
Because, they may be damaged secondarily.
Be sure to find out all defective parts caused by a blown fuse.
Because, if the power is turned on with even one defective part left in the circuit, this may lead the other parts to become
defective again.
