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.

WARNING

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

cause cancer, birth defects or other reproductive harm.

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.

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 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 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

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.

· 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 0.3M

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 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.

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.

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

ha v e 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.

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.
