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.

IMPORTANT
THIS PIONEER APPARATUS CONTAINS
LASER OF CLASS 1.
SERVICING OPERATION OF THE APPARATUS
SHOULD BE DONE BY A SPECIALLY
INSTRUCTED PERSON.
LABEL CHECK (for WY type)
LASER DIODE CHARACTERISTICS
MAXIMUM OUTPUT POWER: 5 mw
WAVELENGTH: 780 – 785 nm
Additional Laser Caution
1. Laser Interlock Mechanism
The position of the switch (S1) for detecting loading
completion is detected by the system microprocessor, and
the design prevents laser diode oscillation when the switch
is not in LPS1 terminal side (when the mechanism is not
clamped and LPS1 signal is high level.) Thus, the interlock
will no longer function if the switch is deliberatery set to
LPS1 terminal side. ( if LPS1 signal is low level ).
In the test mode∗ the interlock mechanism will not function.
Laser diode oscillation will continue, if pin 33 of CXA1782CQ
(IC101) on the MOTHER BOARD ASSY is connected to
GND, or pin 43 of IC701 (LDON) is connected to low level
(ON), or else the terminals of Q101 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. 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 on the product are used for disassembly.

6.2.1 How to Start/Cancel Test Mode
[ Precautions for Test Mode ]
(1) If a soiled or damaged disc is played back and a GFS error is generated, the system may not perform a STOP operation and may run out of
control, although muting ON/OFF will be performed. If the system does run out of control, press the CUE key to switch the power OFF.
(2) Do NOT press any key while an OPEN/CLAMP, SPINDLE KICK, or FOCUS SEARCH operation is in progress. Be sure to wait until the
operation is completed before calling the next operation.

<< PRECAUTIONS >>
Be sure to disconnect the power cable from the AC outlet
whenever removing the card flexible cable from the
connector for maintenance, etc. Hold the both sides of the
card flexible cable with both hands to disconnect the
cable straight. (Even if the power has been switched OFF,
previously charged voltage may remain in the capacitor,
etc. If the electrodes of the card flexible cable and those
of the connector come in contact by accident, a malfunction
may occur.)
