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 Cod e 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.

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 schematics and 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.

Device under test

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

LASER DIODE CHARACTERISTICS MAXIMUM OUTPUT POWER: 5 mw WAVELENGTH: 780 ­ 785 nm

LABEL CHECK (for WY type)

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.

5. PCB PARTS LIST
NOTES : ÷ Parts marked by " NSP " are generally unavailable because they are not in our Master Spare Parts List. mark found on some component parts indicates the importance of the safety factor of the part. ÷ The Therefore, when replacing, be sure to use parts of identical designation. ÷ When ordering resistors, first convert resistance values into code form as shown in the following examples. 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 = 56 × 10 1 = 561 ................................................... RD1/4PU 5 6 1 J 47k = 47 × 10 3 = 473 .................................................. RD1/4PU 4 7 3 J 0.5 = R50 ...................................................................... RN2H Â 5 0 K 1 = 1R0 ......................................................................... RS1P 1 Â 0 K Ex. 2 When there are 3 effective digits (such as in high precision metal film resistors). 5.62k = 562 × 10 1 = 5621 ........................................... RN1/4PC 5 6 2 1 F

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.

7.2.2 DISASSEMBLY
<< 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.)

- MASTER TEMPO button
÷ The master tempo function is turned ON/OFF. ÷ If the button is held depressed for 2 seconds or more, the tempo adjust dial's variable range is changed (±10% or +10% to ­16%). When the variable range is changed, the newly selected numerical range is displayed for about 2 seconds (10.0 / 16.0). ÷ The variable range is set by default to the ±10 setting whenever power is first turned on.

= TIME MODE/AUTO CUE button
Two functions are available. [Time display] Each time this button is pressed, the time display changes between the elapsed playback time of the track and the remaining playback time of the track (REMAIN). ÷ The REMAIN display appears when power is turned ON. [Auto Cue function] When a disc is initially loaded or when performing track search, this function automatically sets the cue point (the point immediately preceding actual sound output). ÷ The Auto Cue function defaults to OFF when power is first turned on.

1 POWER switch
(Located on rear panel) Provides electrical power to the player.

~ TEMPO control knob
The playback tempo can be changed with this knob. The center clicked position is for normal playback tempo. If you slide the knob (down) towards you (+ side), the music tempo quickens. If the knob is away from you (­ side), the music tempo slows.
