1. SAFETY INFORMATIONThis service manual is intended for qualified service technicians; it is not meant for the casualdo-it-yourselfer. Qualified technicians have the necessary test equipment and tools, and have beentrained 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 mayvoid the warranty. If you are not qualified to perform the repair of this product properly and safely, youshould not risk trying to do so and refer the repair to a qualified service technician.

WARNING

This product contains lead in solder and certain electrical parts contain chemicals which are known to the state of California to

cause cancer, bir th defects or other reproductive harm.

Health & Safety Code Section 25249.6 – Proposition 65

1.1 SAFETY PRECAUTIONSNOTICE : Comply with all cautions and safety related notes locatedon 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 theset in safety before any service is performed.

2. When replacing a chassis in the set, all the protective devicesmust 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. Extraprecaution should be taken to assure correct lead dress in thehigh voltage circuitry area.

4. Always use the manufacture's replacement components.Especially critical components as indicated on the circuit diagramshould not be replaced by other manufacture's.Furthermore where a short circuit has occurred, replace thosecomponents that indicate evidence of overheating.

5. Before returning a serviced set to the customer, the servicetechnician must thoroughly test the unit to be certain that it iscompletely safe to operate without danger of electrical shock,and be sure that no protective device built into the set by themanufacture has become defective, or inadvertently defeatedduring servicing. Therefore, the following checks should beperformed for the continued protection of the customer andservice technician.

6. Perform the following precautions against unwanted radiationand 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 doesnot break).

• Make sure that the panel vent does not break. (Check that thecover is attached.)

• Handle the FPC connected to the panel carefully.Twisting or pulling the FPC when connecting it to the connectorwill 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 toTVs and radios in the surrounding.

REMARQUE(POUR MODÈLE CANADIEN SEULEMENT)

Les symboles de fusible (fusible de type rapide) et/ou (fusible de type lent) sur CCI indiquent que lespièces de remplacement doivent avoir la même désignation.

NOTICE

(FOR CANADIAN MODEL ONLY)Fuse symbols (fast operating fuse) and/or (slow operating fuse) on PCB indicate that replacement partsmust be of identical designation.

Leakage Current Cold CheckWith the AC plug removed from an AC power source, place ajumper across the two plug prongs. Turn the AC power switch on.Using an insulation tester (DC 500V), connect one lead to thejumpered AC plug and touch the other lead to each exposed metalpart (input/output terminals, screwheads, metal overlays, controlshafts, etc.), particularly any exposed metal part having a returnpath to the chassis. Exposed metal parts having a return path to thechassis should have a minimum resistor reading of 0.3MW and amaximum resistor reading of 5MW. Any resistor value below orabove this range indicates an abnormality which requires correctiveaction. Exposed metal parts not having a return path to the chassiswill indicate an open circuit.


4

Leakage Current Hot CheckPlug the AC line cord directly into an AC power source (do not usean 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 thechassis, to a known earth ground (water pipe, conduit, etc.). Anycurrent measured must not exceed 0.5mA.

ANY MEASUREMENTS NOT WITHIN THE LIMITSOUTLINED ABOVE ARE INDICATIVE OF A POTENTIALSHOCK HAZARD AND MUST BE CORRECTED BEFORERETURNING THE SET TO THE CUSTOMER.

1.2 PRODUCT SAFETY NOTICEMany electrical and mechanical parts in PIONEER set have specialsafety related characteristics. These are often not evident fromvisual inspection nor the protection afforded by them necessarilycan be obtained by using replacement components rated for highervoltage, wattage, etc. Replacement parts which have these specialsafety characteristics are identified in this Service Manual.Electrical components having such features are identified by markingwith a on the schematics and on the parts list in this ServiceManual.The use of a substitute replacement component which dose not havethe same safety characteristics as the PIONEER recommendedreplacement one, shown in the parts list in this Service Manual, maycreate shock, fire or other hazards.Product Safety is continuously under review and new instructionsare issued from time to time. For the latest information, alwaysconsult the current PIONEER Service Manual. A subscription to, oradditional copies of, PIONEER Service Manual may be obtained ata nominal charge from PIONEER.

7 Charged SectionThe places where the commercial AC power is used withoutpassing 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 theGND of the charged section and the GND of the non-chargedsection while connecting the set directly to the commercial ACpower supply. Therefore, be sure to connect the set via an insulatedtransformer 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 isvery dangerous.)

When the power is turned on with a connector disconnected, and if Low power supply DC-DC Converter operates normally with lightingD355 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.)


64

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 overcurrent, 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 becomedefective again.
