1. SAFETY INFORMATION

This service manual is intended for qualified service technicians ; it is not meant for the casual do-ityourselfer. 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 60Hz outlet and turn the AC power switch on. Any current measured must not exceed 0.5mA.

Reading should not be above

0.5mA

Earth ground

Device under test

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

Leakage current tester

Test all exposed metal surfaces

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 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

47k Ω→47 × 103→ 473 ........................................................ RD1/4PU 4 7 3 J

0.5 Ω→R50 .....................................................................................RN2H

1 Ω→1R0 ..................................................................................... RS1P

Ex.2 When there are 3 effective digits (such as in high precision metal film resistors).

7. GENERAL INFORMATION

7.1 DIAGNOSIS

7.1.1 Test Mode (1) How to enter the test mode

Turn the OUTPUT MODE switch to "OFF" in the POWER OFF state, and turn the POWER ON. Enter the test mode that continues pressing "DIGITAL NR", "TONE" and "REC SELECTOR" keys together for two seconds after passing afterwards more than 15 seconds (In the meantime, because do not accept key operation).

Indicate it with "TEST MODE" in FL.

Set all states to the factory setting state except destination code.

SACD , HDCD lights during test mode.

(2) FL All lights / All lights out

Enter the FL and LED light confirmation mode when pressing the "NETWORK SETUP + DIRECT" keys during test mode. Change the FL indication and LED indication as follows whenever pressing the "NETWORK + DIRECT" keys.

Normal indication → FL, LED all light → FL, LED all light out → Normal indication → ...

(5) Master VOLUME operation confirmation

Enter the operation confirmation mode of master VOLUME when pressing the "NETWORK SETUP + DIGITAL NR" keys during test mode. Switch as follows whenever pressing the "NETWORK+DIGITAL NR" keys.

Last state → - ∞ → -12dB → - ∞ → ...

(MIN)

(6) Communication confirmation with dts

ROM

Enter the communication confirmation mode with dts ROM when pressing the "NETWORK SETUP + fs 96k/48k" keys during test mode. INPUT SELECTOR becomes "DIGITAL 6", then repeat virtual OPTION: on/off whenever pressing the "NETWORK + fs" keys. Indicate it with "DTS ON" at on, and decode of compression audio is possible. Perform the decode operation when inputs the dts signal in this state. If a communication with the dts ROM is performed, outputs it correctly decoded.

Note: Please turn a little MASTER VOLUME after this.

(7) How to cancel the test mode

Turn the POWER OFF, then finish the above operations and cancel the test mode.

(3) Delay confirmation

FL indicates it with "DELAY CHECK" when pressing the "NETWORK SETUP + Hi-bit" keys during test mode and it beomes following setting.

• INPUT selector set to the MULTI-ch mode with the DVD.

• As for the setting of delay, FRONT ch and CENTER ch are 3.0m (10 feet), SURROUND ch is 1.5m (5 feet), and SURROUND ch delays 5 msec only.

Note: Please turn a little MASTER VOLUME after this.

(4) Gain switching confirmation in TONE

on/off

Enter the gain switching confirmation mode of analog circuit when pressing the "NETWORK SETUP + MIDNIGHT" keys during test mode. Switch as follows whenever pressing the "NETWORK + MID NIGHT" keys.

Gain +6dB (last state) → gain 0dB → gain +6dB → ...

(8) Microcomputer version confirmation

Turn the OUTPUT MODE switch to "OFF" and turn the POWER ON. Indicates the version of the microcomputer (system controller and DSP controller) in the FL indicator that continues pressing "PARAMETER CHECK", "MIDNIGHT" and "REC SELECTOR" keys together for two seconds after passing afterwards more than 15 seconds.

Indication example: (System controller) SYS: ∗∗∗

(DSP controller) DSP: ∗∗∗

(9) Key list of the main unit to use

DIGITAL NR + TONE + REC SELECTOR : Enter the test mode

NETWORK SETUP + DIRECT : FL, LED all light / all light out

confirmation mode

NETWORK SETUP + Hi-bit : Delay confirmation mode

NETWORK SETUP + MIDNIGHT : TONE gain switching

confirmation mode

NETWORK SETUP + DIGITAL NR : Master VOLUME

operation confirmation

NETWORK SETUP + fs 96k/48k : dts ROM operation confirmation

PARAMETER CHECK + MIDNIGHT + REC SELECTOR :

Microcomputer version confirmation

Firstly confirm that connection of each connector and FFC are correctly.
