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
Lead in solder used in this product is listed by the California Health and Welfare agency as a known reproductive toxicant which
may cause birth defects or other reproductive harm (California Health & Safety Code, Section 25249.5).
When servicing or handling circuit boards and other components which contain lead in solder, avoid unprotected skin contact with
the solder. Also, when soldering do not inhale any smoke or fumes produced.
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 3.5 mA.
Leakage
current
tester
Device
under
test
Reading should
not be above
3.5 mA
Test all exposed
metal surfaces
Also test with plug
reversed
(Using AC adapter
plug as required)
Earth ground
AC Leakage Test
2
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.

5. PCB 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.
÷ 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 Ω = 56 × 10 1 = 561 ................................................... RD1/4PU 5 6 1 J
47k Ω = 47 × 10 3 = 473 .................................................. RD1/4PU 4 7 3 J
0.5 Ω = R50 ...................................................................... RN2H Â 5 0 K
1 Ω = 1R0 ......................................................................... RS1P 1 Â 0 K
Ex. 2
When there are 3 effective digits (such as in high precision metal film resistors).
5.62k Ω = 562 × 10 1 = 5621 ........................................... RN1/4PC 5 6 2 1 F

7.2 DIAGNOSIS
7.2.1 ERROR CODE DISPLAY
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)

• A disc couldn’t be detected for playback after loading because;
No disc existed.
A disc was turned upside down.
A disc was dirty.
A disc was loaded incompletely.
• The focus got out of place during playback due to the crack
and stain on the disc.
• The servo mechanism couldn’t move to the desired tune
position within a fixed time during selection of a tune from
playback or during playback.

Description
• Mechanism position just before the LOADING mechanism
shifts to the disc selection operation when the DCNT pin is
low. (The DCNT pin is usually high when the LOADING
mechanism is in the stop state. The mechanism position is
thus judged to have been shifted for some reason. The shifted
mechanism position may cause a failure.)
• Discrepancy has occurred between the detected disc position
and the current disc position during movement of the loading
mechanism. (The system may incorrectly counted the
waveforms of the DCNT and DPOS terminals. If counting is
incorrect, the position of the disc No. displayed does not match
the disc position counted.)
• Mechanism position during disc loading when the DCNT pin
is low. (The DCNT pin is usually high when the LOADING
mechanism is in the stop state. The mechanism position is
thus judged to have been shifted for some reason. The shifted
mechanism position may cause a failure.)
• The pickup block cannot return to the innermost circumference
when the playback is completed or another disc is shifted.

A disc was turned upside down.
A disc was dirty
A disc was loaded incompletely.
