SAFETY INFORMATION
A

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.

B

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)
C

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.

D

Leakage
current
tester

Device
under
test

E

Reading should
not be above
0.5 mA

Test all
exposed metal
surfaces

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

Earth
ground

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
on the schematics and
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.

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.

A

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%).
561 ........................................................ RD1/4PU 5 6 1 J
560 Ω
→
56 × 101 →
473 ........................................................ RD1/4PU 4 7 3 J
47k Ω
→
47 × 103 →
0.5 Ω
→
R50 ..................................................................................... RN2H R 5 0 K
1Ω
→
1R0 ..................................................................................... RS1P 1 R 0 K
Ex.2 When there are 3 effective digits (such as in high precision metal film resistors).
5621 ...................................................... RN1/4PC 5 6 2 1 F
5.62k Ω →

[AFTER THE DETECTION]
When above four detection circuits detect the error, the set(M-EV51) enters to the stand-by mode.
Then the stand-by LED blinks and it becomes unable to turn on the power for 60 seconds.
This mode can be cancelled by entering to the TEST MODE at Media Part XV-EV51.
Refer to the protection power off timming chart next page.

7.1.2 OPERATING CONDITION FOR FAN
1) After M-EV51 is set to be turned on the power, the fan rotates at low speed under 13V.
C

2) When CN3501 Pin3 (H/L CONT) becomes about 0.6 ~ 0.85V, the fan rotates at high speed of 20V.

7.1.3 SINGLE OPERATION METHOD
Single operation method and input level.
A

Note : Before the diagnosis, discharge the Amp power line. Connect the resistor of 100Ω or more between W301(VH+), W303(VH–) and
GND (CN3003 Pin1) on the E-VOL ASSY. Refer to the next page about the points.
The procedure and the input level of a single operation are shown below.
1. Short R84 with 1kΩ on the PRIMARY ASSY.
2. The power supply of the unit is turned on.
3. The terminal SPCONT(7 pin of CN3002) on the E-VOL ASSY is controlled by the following voltages.
The initial state is “SP Relay is OFF” and “Sys. Mute is ON”. Apply DC+12V to SPCONT so that AMP can output to the speaker terminal.

4

Remove the rear panel.
Remove E-VOL ASSY and SECONDARY ASSY temporarily.
Remove SECONDARY ASSY.
Remove SP-TERMINAL ASSY.
(Even if this ASSY is removed, VHVL ASSY can operate.)
5 Attach SECONDARY ASSY to E-VOL ASSY again.
6 Put E-VOL ASSY, AMP MODULE and SECONDARY ASSY on the table, and diagnose VHVL AMP ASSY.
Note : The connectors between E-VOL ASSY, SECONDARY ASSY, VHVL AMP ASSY and AMP REG FAN ASSY
(CN3003-CN3, CN3101-CN3301, CN3102-CN3302, CN3104-CN3502, CN3103-CN3501)
are board to board connectors. It is difficult to connect them.
Be sure to confirm the complete connections.
