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.
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
Test all exposed metal surfaces
Leakage current tester
Reading should not be above 3.5 mA
Also test with plug reversed (Using AC adapter plug as required) Earth ground

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 = 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

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)

(1) Disc No. A : Detail of error code at portion
The user display appears only when the normal operation cannot be returned even if the fail safe operation is executed after each error occurs.
User display None A0 Description · 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. · A disc couldn't be loaded within a fixed time. (A disc couldn't be carried from the rack block.) · A disc couldn't be unloaded within a fixed time. (A disc couldn't be returned to the rack block.) · The LOADING mechanism couldn't move to the desired disc position within a fixed time during selection of a disc from playback or during playback start from stop. · The LOADING mechanism couldn't be forcibly returned to the home position (left position when viewed from the front) within a fixed time after it is initialized or becomes NG. · A disc couldn't be normally rotated for playback after loading because; A disc was turned upside down. A disc was dirty A disc was loaded incompletely. · A disc couldn't be normally rotated during playback due to the crack and stain on the disc. User display None A7 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.
