WARNING

This product may contain a chemical known to the State of California to cause cancer, or birth defects or other reproductive
harm.

Health & Safety Code Section 25249.6 - Proposition 65

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.

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 120 V
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 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.

• For environmental protection, lead-free solder is used on the printed circuit boards mounted in this unit.
Be sure to use lead-free solder and a soldering iron that can meet specifications for use with lead-free solders for repairs
accompanied by reworking of soldering.

• Compared with conventional eutectic solders, lead-free solders have higher melting points, by approximately 40 ºC.
Therefore, for lead-free soldering, the tip temperature of a soldering iron must be set to around 373 ºC in general, although
the temperature depends on the heat capacity of the PC board on which reworking is required and the weight of the tip of
the soldering iron.

Do NOT use a soldering iron whose tip temperature cannot be controlled.
Compared with eutectic solders, lead-free solders have higher bond strengths but slower wetting times and higher melting

temperatures (hard to melt/easy to harden).
The following lead-free solders are available as service parts:

• Parts numbers of lead-free solder:
GYP1006 1.0 in dia.
GYP1007 0.6 in dia.
GYP1008 0.3 in dia.

The part listed below is difficult to replace as a discrete component part.
When the part listed in the table is defective, replace whole Assy.

The above-mentioned Display mode is available only when the product operates properly.
If any protection function is activated while the product is in use, the product cannot be turned ON and enter the above

Display mode. In such a case, cancel the protection function, referring to “3.4 How to cancel the status after detection of the
DC error." If a protection function is activated immediately after the previous protection function is canceled, cancel that
protection function again then enter STBY mode immediately. You can then see the error logs, following the above procedures,
until a next protection function is activated.

The protection detection counts cannot be cleared (reset to 000) with the MEMORY CLEAR process.
They can only be cleared when the procedures of Reset mode are completed.

Simultaneously holding the [ADVANCD SURROUND] and [STANDBY/ON] keys on the
front panel pressed for 2 seconds will cancel Key Input Inhibition mode after a DC error
detection and turn the unit ON.

[Detailed explanations]

3.3 TEMP (AMP overheat) error detection

For detection of a TEMP error, the unit monitors both the TR_DET and PROTECT2 signals. If a TEMP error is detected,
the processes shown below will be performed. The processes shown below are rough operational specifications and are
not the actual commands from the mounted components.
After a TEMP error is detected, the count of protection activation detections will be updated.

1. Discharging

(1) Unplug the power cord.
(2) Disconnect the 10P connector from CP403 of the AMP5 Assy between CN3 of the MAIN Assy.
(3) Connect +B and –B terminal of the D7, using resistor leads with 47 - 100 ohms (2 W or higher), for discharging.
∗ Discharging time: 30 - 60 seconds, depending on the level of resistance.
(4) Check that the voltage between the +B and –B terminals is less than 1 V, using a tester.
∗ Be sure to connect the GND terminal of the tester to the chassis.
∗ If the voltage is still 1 V or higher, repeat Step (3).

[1] MAIN Assy Capacitor (C55, C58)

[Procedures]

(1) Unplug the power cord.
(2) Connect –30V and GND terminal of the BRG-C Assy,
using resistor leads with 47-100 ohms (2 W or higher),
for discharging.
∗ Discharging time: 5 - 10 seconds, depending on the
level of resistance.
(3) Check that the voltage between the –30V terminal is less
than 1 V, using a tester.
∗ Be sure to connect the GND terminal of the tester to
the chassis.
∗ If the voltage is still 1 V or higher, repeat Step (2).

• 9P extension jig cable (GGD1739)

• Board to board extension jig cable (GGD1756)

2. Notes on Ground Points Connection

During repair, before checking the MAIN Assy, etc., with the rear chassis removed, be sure to connect the
GND terminal of the main capacitor to the back chassis (speaker chassis), as shown below, then connect the
power cord.

Without grounding connection, the protection circuit will be activated.
After repairing, be sure to remove the ground wire before reassembling.
