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

D

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.

E

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.

• 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 4 MΩ.
The below 4 MΩ 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 1 mA.

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.

1. SERVICE PRECAUTIONS

1.1 NOTES ON SOLDERING

• For environmental protection, lead-free solder is used on the printed circuit boards mounted in this unit.
Be sure to use lead-free solder and a soldering iron that can meet specifications for use with lead-free solders for repairs
accompanied by reworking of soldering.

• Compared with conventional eutectic solders, lead-free solders have higher melting points, by approximately 40 °C.
Therefore, for lead-free soldering, the tip temperature of a soldering iron must be set to around 373 °C in general, although
the temperature depends on the heat capacity of the PC board on which reworking is required and the weight of the tip of
the soldering iron.

A

Compared with eutectic solders, lead-free solders have higher bond strengths but slower wetting times and higher melting
temperatures (hard to melt/easy to harden).

The following lead-free solders are available as service parts:

• Parts numbers of lead-free solder:
GYP1006 1.0 in dia.
GYP1007 0.6 in dia.
GYP1008 0.3 in dia.

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.

other than the Charged Section.

High Voltage Generating Point

The places where voltage is 100 V or more except for the charged
places described above. If the places are touched, there is a risk of
electric shock.
The VSUS voltage remains for several minutes after the power to
the unit is turned off. These places must not be touched until
about 10 minutes after the power is turned off, or it is confirmed
with a tester that there is no residual VSUS voltage.

If the procedures described in “5.6.1 PANEL DRIVE-POWER
ON/OFF FUNCTION” are performed before the power is turned
off, the voltage will be discharged in about 30 seconds.

Notes when visiting for service

1. Notes when disassembling/reassembling

1 Rear case

When reassembling the rear case, the screws must be tightened in a
specific order. Be careful not to tighten them in the wrong order forcibly.
For details, see "Rear Case" in "7. DISASSEMBLY".

2 Attaching screws for the HDMI connector

When attaching the HDMI connector after replacing the Main Assy,
secure the HDMI connector manually with a screwdriver, but not
with an electric screwdriver. If you tighten the screws too tightly
with an electric screwdriver, the screw heads may be damaged, in
which case the screws cannot be untightened/tightened any more.

2. On parts replacement

1 How to discharge before replacing the Assys

A charge of significant voltage remains in the Plasma Panel even
after the power is turned off. Safely discharge the panel before
replacement of parts, in either manner indicated below:

Let the panel sit at least for 3 minutes after the power is turned off.

A:
B: Turn the Large Signal System off before the power is turned off
then, after 1 minute, turn the power off.
For details, see "5.6.1 PANEL DRIVE-POWER ON/OFF
FUNCTION".

2 On the settings after replacement of the Assys

Some boards need settings made after replacement of the Assys.
For details, see "8. EACH SETTING AND ADJUSTMENT".

3. On various settings
