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.

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 perfor med for the
continued protection of the customer and ser vice
technician.
LEAKAGE CURRENT CHECK
Measure leakage current to a known ear th ground
(water pipe, conduit, etc.) by connecting a leakage
current tester such as Simpson Model 229-2 or
equivalent between the ear th ground and all exposed
metal par ts 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 character istics. 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 par ts which have these
special safety character istics are identified in this
Service Manual.
Electr ical 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
infor mation, always consult the current PIONEER
Service Manual. A subscription to, or additional copies
of, PIONEER Ser vice 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 x 10 1
RD1/4PU 5 6 1 J
561
47k Ω
RD1/4PU 4 7 3 J
47 x 10 3
473
0.5 Ω
RN2H R 5 0 K
R50
1Ω
RS1P 1 R 0 K
1R0
Ex.2 When there are 3 effective digits (such as in high precision metal film resistors).
5.62k Ω
562 x 10 1
5621

Each time the remote control code is received, the indications on
the FL and LED change cyclically, as shown below.
All segments on the FL and LED light. → All segments on the
FL and LED go off. → "ABCDEFGH" are displayed on the FL,
and 1, 3, 5, 7 are displayed on the LED. → "IJKLMNOP" are
displayed on the FL, and 2, 4, 6, 8 are displayed on the LED. →
Usual display → . . . .
When the code is first received, all segments light.
4. SP relay change

• When Analog Input Check mode is entered, "SIG:ANA" is
displayed for 5 seconds.
"1" key
When the code is received, the versions of the main
microcomputer, display microcomputer, and DSP are displayed.
After the versions of microcomputers are displayed for 5 seconds,
DSP version is displayed for 5 seconds.
Examples:
"M011F001": Main microcomputer: Ver. 011, display
microcomputer: Ver. 001
"PPP. 031": DSP: Ver. 031
"1" key
Each time the remote control code is received, the SP relay is
turned off then back on. When the code is first received, the SP
relay is turned off.
5. DOLBY Pro Logic2 mode
Note : Test mode of No. 1-12 is Preset ID 150.
Test mode of No. 13, 14 is Preset ID 156.

7.1.3 Specifications of Speaker Detection
1. Purposes
A
Automatic detection of connected speakers and automatic selection of settings appropriate for the detected speakers allow you to easily
play surround-sound without your making cumbersome speaker settings.
2. Speaker detection method
Automatic detection of connected speakers starts 1120 ms after the power is turned on.
• Detection of the center and surround speakers
The microcomputer sends a detection signal and reads the logic of the response signal to judge whether the speaker is connected or not.
The response signal is read at A/D input, and a voltage of 3 V or more is judged as no speaker connected.
• Detection of the subwoofer
The logic of the signal from the phono jack with a switch is read by the microcomputer to judge whether a speaker is connected or not.
B
3. Speaker settings
According to the results of detection, speaker settings are made as shown below.
Rules: The setting for the front speakers depends on whether a subwoofer is connected or not. If a subwoofer is connected, the setting for
the front speakers is "small." Settings for other speakers are "small" or "not connected" depending on the results of detection.
Settings for the rear surround speakers are in effect only when surround speakers are connected.

4 User's settings
More detailed speaker settings can be made in Setup mode. Once the user's settings are made in Setup mode, those settings have priority.
However, if the configuration of connected speakers changes, then the detection results become valid and have priority over the user's
settings until new user's settings are made.

• In Normal mode, as Q101 (Q103) (E2, B2, C2) and Q102 (Q104)
(E2, B2, C2) are on, the voltage at Point A is about 5 V.
The voltage at Point B is therefore about the same. As Q101
(Q103) (E, C, B) is off, Q102 (Q104) (E, C, B) is also off.
(1) When VH+(VP+15) is short-circuited to GND
As the voltage at Point B becomes almost ground potential, and
Q101 (Q103) (E, C, B) then Q102 (Q104) (E, C, B) are turned on,
the level of XPROTECT becomes low.
→ The microcomputer detects the XPROTECT level and shuts the
power to the unit off.
(2) When VH–(VA–12) is short-circuited
As the electric potential of VE at Q102 (Q104) (E2, C2, B2)
becomes the same as that at VB, Q102 (Q104) (E2, C2, B2) is
turned off. Following this, Q101 (Q103) (E2, B2, C2) is turned off,
which changes the voltage at Points A and B to a value other than
5 V. Therefore, Q101 (Q103) (E, C, B) then Q102 (Q104) (E, C, B)
are turned on, the level of XPROTECT becomes low.

If no fan is connected between FAN+ and FAN-, or when the fan
cannot rotate because of a foreign object caught in the blades, the
BASE of Q3652 becomes OPEN, and Q3652 and Q3651 (E, C, B)
are turned off. Then Q3651 (E2, B2, C2) is turned on, and the level
of XPROTECT becomes low.
When FAN+ and FAN- are short-circuited, the electric potential at
Point (A) becomes higher than GND level by the addition of the
values at D3656 and D3657. As this value is lower than that at
D3658, Q3651 (E, C, B) is turned off, Q3651 (E2, B2, C2) is turned
on, and the level of XPROTECT becomes low.

(3) When VD+5 is short-circuited
The level of the XPROTECT line becomes low. The microcomputer
detects the XPROTECT level and shuts the power to the unit off.
