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 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 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
0.3MΩ and a maximum resistor reading of 5MΩ. 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.
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 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.

After adjusting the white balance, check the face colour of figures
in LD still pictures.
If the colour is not natural, adjust COLOUR and TINT and
memorize the value.
2. Picture quality check
Set the sharpness to 120 for both NTSC and HDTV, and the detail
setting to 70 for NTSC and 65 for HDTV, and check the picture
quality.
Note: Adjust the white balance and check the picture quality in each
NTSC screen mode (natural wide, zoom, etc.) and HDTV
(MUSE).

Note 2) In some models, BMZ40P120FMC screws will be used for
screw 1' instead of BPZ40P160FZK which is used for
screw 1.
Note 3) The front case may be difficult to remove at point A at the
center of the upper side of the rear case because the boss of
the front case is passed through the plate hole as shown in
Fig. 2 and joined to the rear case. In such cases, push the
tip of the boss with a screwdriver to release the front case
from the rear case.

aluminum sash.
2) Remove all panel shields 1 and 3 and panel holders 2 and 4.
3) Remove and replace the front protection panel.
4) Attach the protection panel by attaching to the bottom left side
first, and then attach the front case assembly in the reverse
procedure of the above.

PDP-501MX, PDP-V501X
When securing the front case to the unit, attach the two bosses
D (one each on the two edges of the top) as a guide so that the
boss at the center A passes through the hole on the rear case.
Note)
When attaching the panel shield and panel holder after replacing
the protection panel, the panel shield may deform when tightening
the screws 3 as shown in Fig. 4. If it deforms, untighten screws
3 slightly and tighten until just before it starts to bend.

2. Abnormal Power Off Circuit
This unit comes equipped with various protection circuits.
When these protection circuit operates, P.D. (Power Down) operates
to turn off the relay (RL1) inside the POWER SUPPLY MODULE.
And turn off the power of the unit.
• X DRIVE (A) /(B) assembly
1) PD due to the over-current detection of the X drive power supply
VCP+12V
2) PD due to the over-current detection of the X drive (+) reset
circuit
• Y DRIVE (A) /(B) assembly
1) PD due to the over-current detection of the Y drive power supply
VCP+12V
2) PD due to the over-current detection of the Y drive (–) reset circuit
3) PD due to the over-voltage detection of the Y drive D-D converter
output VH150V
4) PD due to the over-current detection of the Y drive D-D converter
output VH150V

• POWER SUPPLY MODULE
1) PD due to the over-current detection of the large power supply
(V
2) PD due to the over-voltage detection of the large power supply
(VSUS+175V, VCSP+40V, VRN–190V , VADR+30V)
3) PD due to the over-current detection of the small signal power
supply (+12V, +5V, +3.3V)
4) PD due to the over-voltage detection of the small signal power
supply (+12V, +5V, +3.3V)
Note) +5V is supplied to K2609 and K3109 of the PD terminal of
each drive assembly when drive assembly PD occurs.
