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 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.

8 There should be no semi-broken wires , scratches, melting, etc. on the coating of the pow er cord.
Damaged power cords may lead to fire accidents, so please be sure that there are no damages .
If you find a damaged power cord, please exchange it with a suitab le one.
9 There should be no spark traces or similar marks on the power plug.
When spark traces or similar marks are found on the power supply plug, please check the connection and advise on secure
connections and suitable usage. Please exchange the po wer cord if necessary .
a Safe en vironment should be secured during servicing.
When you perform repairs, please pay attention to static electricity, furniture, household articles, etc. in order to pre vent injuries.
Please pay attention to your surroundings and repair safely.
2. Adjustments
T o k eep the original performance of the products, optimum adjustments and confirmation of characteristics within specification.
Adjustments should be performed in accordance with the procedures/instructions described in this manual.
4. Cleaning
For parts that require cleaning, such as optical pickups, tape deck heads, lenses and mirrors used in projection monitors, proper
cleaning should be performed to restore their performances.
3. Lubricants, Glues , and Replacement parts
Use grease and adhesives that are equal to the specified substance.
Make sure the proper amount is applied.
5. Shipping mode and Shipping scre ws
T o protect products from damages or f ailures during transit, the shipping mode should be set or the shipping screws should be
installed before shipment. Please be sure to follo w this method especially if it is specified in this manual.

• 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.

Simplified diagnosis
Errors in the Audio Block of the DIGITAL MAIN Assy (those simply and roughly predictable by machine operation only)
• Sound abnormality in Delay
If sound abnormality does not occur in the Delay OFF state but occurs in the Delay ON state, it is most likely that a failure
has occurred in SDRAM (IC251) or LATCH (IC281, IC291) in the DSP Block.
• No sound at analog signal input
If sound abnormality does not occur with digital signal input (COAX, OPT, etc.) but occurs only with analog signal input,
it is most likely that a failure has occurred in the AD converter (IC501).
• No sound with the PQLS ON (normal sound with the PQLS OFF)
If no sound is output during CD playback with the PQLS ON, it is most likely that a failure has occurred in the crystal
oscillator (X361). (Diagnosis point A)
<If no sound is output in Multi-Channel-Signal Playback or Surround mode with the COAX, OPT, USB, and HDMI inputs>
• Assume that the LCRs are neither in poor connection nor damaged.
• Assume that diagnosis is performed from Side A.
• This shows failure analysis for the DSP Block of the DIGITAL MAIN Assy.

To detect amplifier damage
(defect status)
A process to protect speakers
(for protection of connected
external devices)
Detects when the DC_PROTECT
port becomes "L".
(Pin 80 of IC3004)
Turns muting on and
speaker relay off, then
turns off the power after 3
seconds. Then flashes
MCACC indicator.
Flashing "AMP ERR" for
3 seconds.
Once detected and turned
the power OFF.
Standby/ON button will be
disabled. Press “TUNE-” &
“Multi-zone ON/OFF”
button together for 5
seconds, the unit will
re-check again the DC
detection port. If the DC
detection port become “H”
for 3 seconds, the unit will
returns to normal condition
automatically.
AMP
overload
To detect overloading
(abnormal status)
With low-load driving or a
short circuit of the speaker
terminals (for protection of the
amplifier)
Detects when the OL_DET port
becomes "L" (checks by interrupt).
(Pin 71 of IC3004)
Turns muting on and
speaker relay off, and
immediately turns off the
power. Then flashes
PHASE CONTROL
indicator.
During Standby mode, simultaneously press and hold the "TUNE-" and "MULTI-ZONE ON/OFF" keys
for 5 seconds.
[How to Enter Release Mode]
After a failure in the amplifier block or high DC output is detected,
the shutdown process starts, then the power will be shut off.
Then the ADVANCED MCACC LED will flash.
The power cannot be turned on again.
If you wish to turn on the unit after a shutdown activated by DC
detection, enter DC detection cancellation mode,
by proceeding with the steps described in "How to enter release
mode" below.
Upon detection of overcurrent at the amp output stage,
the unit power off immediately,
and the PHASE CONTROL LED starts flashing.
The previous stage will be restored when the unit
is turned back on.
If abnormality voltage is detected in the power supply
VPRE circuit, the unit power off immediately, and the
POWER LED starts flashing.
To restore the previous status, turn the unit back on
after 1 minutes.
If abnormality voltage is detected in the Digital power supply
circuit, the unit power off immediately, and the
CENTER BLUE LED starts flashing. To restore the
previous status, turn the unit back on.
The connected USB device is overload.
The monitor does not support HDCP type or is
in standby mode.

Preparations Before Performing Diagnosis of the POWER PACK Assy
Before performing diagnosis of the POWER PACK Assy, it is necessary to discharge C5301 and C5302 on the board.
(See the photo below.)
If you don’t, the Power Pack ICs (IC5001, IC5002, and IC5003) on the board may be damaged.
1. Unplug the power cord.
2. Lift the UL tube at the location near C5301 and C5302 so that the periphery of D5301 becomes accessible.
3. Connect J192 and J1005 (or J1006 or J1007), as well as J195 and J1005 (or J1006 or 1007).
With the above connections, Pins 1 and 4 of D5301 are grounded to the ground points and discharged.
Note: For discharging, use a load of 100 Ω , 3 W or more, to protect the IC protectors. Do NOT discharge instantly by
short-circuiting.
4. Check that the voltage between the electrodes of each C5301 and C5302 is 1 V or less.
