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

B

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.

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 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.

NOTES:

Mark No. Description Part No.

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
47k Ω

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

• 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.

A

B

In Normal mode, the speaker (6 ohms) is connected between the
FL and GND FL points. Because the voltage at Point A is higher
than that at Point B, Q4205 does not operate.

If the resistance between the FL and GND FL points becomes

1.83 ohms or less, Q4205 begins to operate, Q4212 is turned on,
Q4211 (E, C, and B)is turned on, and the level of XPROTECT
becomes MID.
→ The microcomputer detects the XPROTECT level and
shuts the power to the unit 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.

(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.

When FAN+ and FAN- are short-circuited, the electric potential at

Point A becomes higher than GND level by the addition of the

The voltage at Point A becomes the divided voltage of TH111
and R111//R112 (combined resistance of parallel-connected
resistors R111 and R112.) In Normal mode, the resistance at
TH111 is much higher than R111//R112, and Q111 is off. (Note
that the resistance at TH111 becomes lower as the temperature
increases.) If the solder temperature at IC81 increases abnormally,
the temperature at TH111 (thermistor) mounted closest to the land
of IC81 increases accordingly, and the resistance at TH111
decreases.
When the temperature at TH111 reaches 90-110_C (varying
according to conditions,) the voltage at Point (A) becomes high
enough to turn Q111 on, and the level of the XPROTECT line
becomes low. The microcomputer detects the XPROTECT level
and shuts the power to the unit off.

• In Normal mode, both Q4214 and Q4213 are off.

(1) When positive (+) DC voltage is generated at the SP
terminal

When positive (+) DC voltage is generated at the L or R channel,

E

and VB of Q4214 becomes higher than that at the operation point,
Q4217 (E, C, B) is turned on, and the level of Q4221 (Q4219)'s
Base becomes low.
→ Q4222 (Q4220) is turned off, and Speaker Relays are
turned off.

(2) When negative (-) DC voltage was generated at the SP
terminal

Q4213 is turned on, and Speaker Relays are turned off.
