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

1. SERVICE PRECAUTIONS
1.1 NOTES ON SOLDERING
A
• 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 °C.
Therefore, for lead-free soldering, the tip temperature of a soldering iron must be set to around 373 °C 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).
B
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.
C
1.2 AMPLIFIER FAILURE DIAGNOSIS FLOW CHART
Amplifier failure diagnosis flow chart
When DC detection is activated ("AMP_ERR" flashes on the display), failure (damage) of the power amplifier
section is considered.
D
Caution:
When releasing the lock state of power key before repair, please be careful because there is the
possibility that more damages will occur when turning on the power once again!
• According to a symptom, perform the following confirmation beforehand.
1) Are there any Fuses and IC protectors open?
↓
2) After turn on the power, confirm that the supply voltage of the point that can be measured is appropriate.
(Particularly the supply voltage of the power Tr and drive step)
↓
3) Whether the voltage of pin2 and pin5 of IC601 or IC603 is equal to (VL-0.7V). If not (eg, equal to VH),
then change the corresponding power pack IC601 or IC603.
↓
4) Furthermore, check the output DC voltage of each channel of power pack IC601 and IC603
to limit the failure channel and identify the defect power pack.
E
↓
• After identify the failure channel, check that each part is not damaged (resistor, diode... etc. value / open /
short)

[2] USB TROUBLESHOOTING
Description of Error Indications
FL Display
A
Error Content
Possible causes and actions to be taken
USB ERROR1
Detection of overcurrent to a USB device
Overcurrent (500 mA or more) is consumed at the connected USB device.
• Some USB devices, such as a portable HDD, need more current than that
this unit supplies. (Use the AC adaptor for the connected USB device.)
• The USB power is short-circuited.
USB ERROR2
Detection of a medium not supported
A USB device that this unit does not support (other than the Mass Storage
Class) is connected (such as a mouse, printer, or digital camera).
• Connect a mass storage class USB device.
USB ERROR3
Communication error with the system
microcomputer
Communication between TCC8600-00X-EA-UG (IC401) and PEG467/469A
(IC9001) failed.
• Defective connection (connectors) inside this unit
• See STEP 3 of Troubleshooting.
B
If a USB ERR message lights in the display, try following the points below:
• Switch the receiver off, then on again.
• Reconnect the USB device with the receiver switched off.
• Select another input source (like DVD/BD), then switch back to USB.
• Use a dedicated AC adapter (supplied with the device) for USB power.
If this doesn’t remedy the problem, it is likely your USB device is incompatible.
Operations when overcurrent to a USB
device is detected
(1) Overcurrent to a USB device is detected at the port for
the microcomputer.
In this state, flashing of "USB ERROR1" stops, but
playback will not start. To start playback, press the USB
play key again.
C
In the above case, if overcurrent is detected again, the
above procedures 1 through 4 are repeated.
(2) The power supply to the USB device is stopped.
(3) Control of 5 V power is disabled at the port for the
microcomputer.
In a case where a medium not supported
is connected
(4) Change of indications on the FL display

(5) To supply power to the USB module again:
• Turn the power to the unit off then back on.
• Set the function setting to anything other than USB
then back to USB.
• Press the USB play key on the remote control unit.
(6) After overcurrent is detected, if the USB play key is
pressed while the error indication is displayed, power
supply to the USB module is restored. If overcurrent
is no longer detected, the indications shown below are
displayed (normal indication):
E R R 2
If overcurrent is detected before detection of a
non-supported medium, the error indication "USB
ERROR1" remains, as the power supply to the USB module
is stopped.
On supported media
The formats of supported media that can be played back on
this unit are MP3, WMA, and AAC.
Some media in MPEG4 can also be played back. As AAC
derives from MPEG4 codec, playback of media in AAC
codec of MPEG4 is possible.

5.3 AMPLIFIER SYSTEM PROTECTION OPERATION SPECIFICATION
1. DC-abnormality detection
DC detection is only enabled 2 seconds after power-on.
If there is a fault in the power amplifier or a high-level signal lower than 5 Hz is input,
the DC_DET port becomes “L”.
If the “L” is detected, the microprocessor will perform as following flow chart.
A
In the case of simultaneous detection with the overload protection circuit,
DC-abnormality detection is performed preferentially to overload detection.
When a DC abnormality is detected, A.MUTE* is turned
on, speaker relay is turned off, then
"AMP_ERR" flashes on the display.
*A.MUTE : Audio mute command
B
↓
The abnormality continues for 3 seconds.
↓ Continues.
↓ Recovery
The program restarts.
The power is shut off.
↓
Power key not effective and POWER LED blinks (only for VSX-918V).
However, when the following keys are pushed so that the key input of a line and the service can
be carried out, power can be on.
1 TESTMODE ON (A55F+A55F)
2 When power off, push TUNE+ key + AUTO SURR/DIRECT key continuously 2sec.
(2: When a DC abnormality is detected and the power is shut off.)
Any other key input from front panel or remote control will not be detected.
C
2. Overload detection
If the speaker terminals are short-circuited or low-load driving is detected, the OL_DET port becomes “L”.
If the “L” is detected, the microprocessor will perform as following flow chart.
When an overload is detected, A.MUTE* is turned on,
speaker relay is turned off, then
"OVERLOAD" flashes on the display.
D
↓
The abnormality continues for 3 seconds.

3. XPROTECT detection
XPROTECT is started to be monitored 200msec after power on.
XPROTECT port is checked every 20msec.
If Low level (ERROR) is recognized during consecutive 9 times, micon judge it as XPROTECT ERROR.
A
It processes more preferentially than DC abnormal detection and overload detection.
POWER ON
↓
When 200 msec passed after power on,
the XPROTECT detection starts.
Don't detect it during power off.
↓
If micon detect XPROTECT = Low
for 200 msec, it judge as error,
and then AMUTE on, speaker relay off
and shut down power supply immediately.

4. Fan stop detection operation flow in the XPROTECT detection
If the fan is forcibly stopped or become out of order, the 'XPROTECT' port becomes "L". Then an abnormality of
fan is detected.
• Detection routine and recovery is same as "3. XPROTECT detection".

NOTES:
A
B
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%).
561
56 x 10 1
RD1/4PU 5 6 1 J
560 Ω
47k Ω
47 x 10 3
473
RD1/4PU 4 7 3 J
0.5 Ω
R50
RN2H R 5 0 K
1R0
