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

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

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

47 x 10 3
473
0.5 Ω
RN2H R 5 0 K
R50

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

7.1.2 HOW TO DIAGNOSE THE AMPLIFIER SECTION
A
When DC detection worked (STBY IND. flashes for a long time)
in the protection circuit of foregoing section (or there is not the
speaker output, probably only 1CH), failure (damage) of the
power amplifier section is considered.
Because this receiver cannot diagnose the amplifier section by an
electricity state by structure, please diagnose it in the following
steps.
Caution:
When release the STBY (flashes) state before repair, Because
there is the case that the damage progresses when turns the power
on once again, please be careful.
B
• According to a symptom, perform the following
confirmation beforehand.
1. Are not Fuse and IC protector opening it?
2-a. When can turn on electricity, confirm that supply voltage of
the point that can measure is appropriate.
2-b. Furthermore, confirm that voltage ((in a no signal) DC and
the appropriate signal output) between GND and R2008R2014 on the SP/PS Assy (Either of the amplifier side and
the speaker terminal side is possible) (Or remove either of
CN2101-2104) on the SP/PS Assy. And limit failure CH.
If was able to limit failure CH, diagnose the CH in the following
steps.
C
• Use the tester basically and check that each part is
not damaged (resistance value / open / short circuit).
About parts with damaged possibility, explain FL ch to an
example in order.

7.1.3 HOW TO DIAGNOSE THE UNIT WITH THE POWER AMPLIFIER SECTION REMOVED
Purpose:
When repairing this unit, the large Heat Sink Block obstructs access to some Assys.
If the Heat Sink Block is removed, as the posistor mounted on it is also disconnected, the protection circuit is activated, which
disables failure diagnosis of these Assys while the unit is powered. With the method explained here, the Assys that cannot be
diagnosed while the unit is powered because of the Heat Sink Block can be diagnosed by creating an artificial status of the
posistor's being connected (by connecting a 100-ohm resistor under normal temperature).
A
Note: Use this method for diagnosing a failure other than possible failures inside the Heat Sink Block, such as those shown in
the table below:
Symptoms that are highly suspected to be
failures inside the Heat Sink Block
1 No power with the STBY LED flashing
2 The unit turns itself off after "AMP ERR" was displayed on the
FL display. Then it goes into state 1 above.
3 "OVERHEAT" is displayed on the FL display under normal
temperature, then the unit turns itself off.
Possible causes
DC detection has been activated to prevent further damage to the unit.
Note: Refer to "7.1.2 How to diagnose the Amplifier Section" in the
service manual.
B
The peripheral circuits of the posistor inside the Power Amplifier Section
are in failure. Note: A posistor is a kind of thermistor, and its resistance is
approx. 100 ohms at normal room temperature.
Overloaded amplifier, failure in the overload-detection circuit inside the
Power Amplifier Section, etc.

8 Secure the POWER PROTECT Assy so that it will not
come into contact with metallic parts of the unit, such as
the chassis. Then connect the POWER PROTECT Assy
with the MAIN CONTROL Assy using an FFC cable and
turn on the power. The unit will be turned on without the
protection circuit activated.
9 After finishing diagnoses, remove the three resistors
inserted in Step 7, and before returning the Power
Amplifier to its original position, discharge the electrolytic
capacitors in the places shown in the table below.
• Turn on the power.

• If connection is made without discharging the electrolytic
capacitors, the resistors may be damaged by a surge of
current.
• Discharge the electrolytic capacitor using a resistor, not by
short-circuiting it. Using a tester, etc., completely
discharge it until there is no remaining voltage.

7.1.5 TROUBLE SHOOTING OF THE DSP ASSY
• When a sound is not out in the multi-channel signal playback or surround mode with the digital signal input.
(SurroundBack is not out with the setting.)
• Suppose CR to be poor contact and that is not damaged.
• This shows failure analysis of DSP Assy.

Step 0: Preliminary check
Step 3: Regulator IC
• Tighten the COAX Jack screws.
(GND of the DSP module floats from the chassis. And this unit
may not work normally, because the electric potential becomes
unstable.)
