1. 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.

(FOR USA MODEL ONLY)

1. SAFETY PRECAUTIONS

The following check should be performed for the

continued protection of the customer and service
technician.

LEAKAGE CURRENT CHECK

Measure leakage current to a known earth ground
(water pipe, conduit, etc.) by connecting a leakage
current tester such as Simpson Model 229-2 or
equivalent between the earth ground and all exposed

metal parts of the appliance (input/output terminals,
screwheads, metal overlays, control shaft, etc.). Plug
the AC line cord of the appliance directly into a 120V
AC 60 Hz outlet and turn the AC power switch on. Any
current measured must not exceed 0.5 mA.

Reading should
not be above

0.5 mA

Earth ground

Device
under
test

Also test with plug
reversed
(Using AC adapter
plug as required)

Leakage

current

tester

Test all exposed
metal surfaces

AC Leakage Test

ANY MEASUREMENTS NOT WITHIN THE LIMITS
OUTLINED ABOVE ARE INDICATIVE OF A PO­TENTIAL SHOCK HAZARD AND MUST BE COR­RECTED BEFORE RETURNING THE APPLIANCE
TO THE CUSTOMER.

2. PRODUCT SAFETY NOTICE

Many electrical and mechanical parts in the appli­ance 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
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 parts list in this Service Manual.
The use of a substitute replacement component which
does 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.

2. EXPLODED VIEWS AND PARTS LIST

NOTES : ÷ Parts marked by “ NSP ” are generally unavailable because they are not in our Master Spare Parts List.

÷ The mark found on some component parts indicates the importance of the safety factor of the part.

Therefore, when replacing, be sure to use parts of identical designation.

÷ Screw adjacent to

mark found on some component parts indicates the importance of the safety factor of the part.

Therefore, when replacing, be sure to use parts of identical designation.

Ex. 1 When there are 2 effective digits (any digit apart from 0), such as 560 ohm and 47k ohm (tolerance is shown by

J = 5%, and K = 10%).
560 Ω = 56 × 10

If a failure occurs in the Loading mechanism, the error symbol is automatically displayed on the fluorescent display screen of the front panel.

7.2.2 ERROR HISTORY and DISPLAY

Error history display in test mode

The previously generated errors (NG processing) can be confirmed in the test mode. Since the has a backup function, the error history is
memorized even if the power is turned off. (Memory holding time : About two days)

No disc existed.
A disc was turned upside down.
A disc was dirty.
A disc was loaded incompletely.

A5 • The LOADING mechanism couldn’t be forcibly returned to

the home position (left position when viewed from the front)

1. 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.

THIS PIONEER APPARATUS CONTAINS

IMPORTANT

LASER OF CLASS 1.
SERVICING OPERATION OF THE APPARATUS
SHOULD BE DONE BY A SPECIALLY
INSTRUCTED PERSON.

LASER DIODE CHARACTERISTICS
MAXIMUM OUTPUT POWER: 7 mw
WAVELENGTH: 780 – 785 nm

LABEL CHECK for (PD-F958/MYXQ and PD-F958/MVXQ types)

PD-F958/MYXQ only

Additional Laser Caution

1.Laser Interlock Mechanism
The position of the switch (S651) for detecting loading
state is detected by the system microprocessor, and
the design prevents laser diode oscillation when the
switch (S651) is not on CLMP terminal side (CLMP

REAR

signal is OFF or high level).
Thus, the interlock will no longer function if the switch (S651)
is deliberatery set to CLMP terminal side. (low level)
The interlock also does not function in the test mode *.
Laser diode oscillation will continue, if pin 33 of
CXA1782CQ (IC151) on the MOTHER BOARD ASSY
is connected to GND, or pin 22 of IC301 (LDON) is
connected to low level (ON), or else the terminals of
Q151 are shorted to each other (fault condition).

2.When the cover is opened, close viewing of the
objective lens with the naked eye will cause exposure
to a Class 1 laser beam.

2. CONTRAST OF MISCELLANEOUS PARTS

NOTES : ÷ Parts marked by “ NSP ” are generally unavailable because they are not in our Master Spare Parts List.

÷ The
