About lead free solder

All of the P.C.B.s installed in this unit and solder joints are soldered using the lead free solder.
Among some types of lead free solder currently available, it is recommended to use one of the following types for the re-
pair work.
• Sn + Ag + Cu (tin + silver + copper)
• Sn + Cu (tin + copper)
• Sn + Zn + Bi (tin + zinc + bismuth)

Caution:
As the melting point temperature of the lead free solder is about 30°C to 40°C (50°F to 70°F) higher than that of the lead
solder, be sure to use a soldering iron suitable to each solder.FRONT PANEL

■ SERVICE PRECAUTIONS
Safety measures
• Some internal parts in this product contain high voltages and are dangerous.
Be sure to take safety measures during servicing, such as wearing insulating gloves.
• Note that the capacitors indicated below are dangerous even after the power is turned off because an electric charge
remains and a high voltage continues to exist there.
Before starting any repair work, connect a discharging resistor (5 k-ohms/10 W) to the terminals of each capacitor indi-
cated below to discharge electricity.
The time required for discharging is about 30 seconds per each.

● Starting Self-Diagnostic Function in the protection cancel mode

If the protection function works and causes hindrance to troubleshooting, cancel the protection function by the procedure
below, and it will be possible to enter the selfdiagnostic function mode. (The protection functions other than the excess
current detect function will be disabled.)
While pressing the TONE CONTROL and INFO keys, press the MAIN ZONE z key to turn on the power and keep
pressing those 2 keys and MAIN ZONE z key for 3 seconds or longer.
The self-diagnostic function mode is activated with the protection functions disabled.
In this mode, the SLEEP segment of the FL display ﬂashes to indicate that the mode is self-diagnostic function mode with
the protection functions disabled.

CAUTION!
Using this unit with the protection function disabled may cause further damage to this unit. Use special care for this point
when using this mode.

● Canceling Self-Diagnostic Function

1. Before canceling self-diagnostic function, execute setting for S3. FACTORY PRESET menu. (Memory initialization in-
hibited or Memory initialized).
* In order to keep the user memory preserved, be sure to select PRESET INHIBIT (Memory initialization inhibited).
2. Press the MAIN ZONE z key to turn off the power.

● Display provided when Self-Diagnostic Function started

The display is as described below depending on the situation when the power to this unit is turned off.

1. When the power is turned off by usual operation:

NO PROTECT is displayed. Then A1-1. DSP THROUGH is displayed in a few seconds.

2. When the protection function worked to turn off the power:

The information of protection function which worked at that time is displayed. Then A1-1. DSP THROUGH is dis-
played in a few seconds.
Note: At that time if you restart the self-diagnostic function after turning off the power once, NO PROTECT will be dis-
played. That is because that situation is equal to 1. When the power is turned off by usual operation: .
However history of the protection function is stored in memory as backup data. For details, refer to T4. PRO-
TECTION DETECTION menu.
2-1. When there is a history of protection function due to excess current.

I PROTECT

Cause: An excessive current ﬂowed through the power ampliﬁer.

Supplementary information: As current of the power ampliﬁer is detected, the abnormal channel can be identiﬁed by
checking the current detect transistor.

RX-V685
Turning on the power without correcting the abnormality will cause the protection function to work immediately and the
power supply will instantly be shut off.

Notes:
• Applying the power to this unit without correcting the abnormality can be dangerous and cause additional
circuit damage. To avoid this, if I PROTECT protection function works 1 time, the power will not turn on even
when the MAIN ZONE z key is pressed. In order to turn on the power again, start up the self-diagnostic func-
tion.
• The output transistors in each ampliﬁer channel should be checked for damage before applying power to this
unit.
• Ampliﬁer current should be monitored by measuring DC voltage across the emitter resistors for each channel.

2-2. When the protection function worked due to abnormal DC output.

DC PRT:xxx
xxx: A/D conversion value of voltage at the moment when the protection function worked
(Reference voltage: 3.3 V=255)

Cause: DC output of the power ampliﬁer is abnormal.

Supplementary information: The protection function worked due to a DC voltage appearing at the speaker terminal. A
cause could be a defect in the ampliﬁer.
Turning on the power without correcting the abnormality will cause the protection function to work in 5 seconds and the
power supply will be shut off.

29
RX-V685

2-3. When the protection function worked due to abnormal voltage in the power supply section.

PS PRT:xxx
xxx: A/D conversion value of voltage at the moment when the protection function worked
(Reference voltage: 3.3 V=255)

PS1/PS2/PS3

Cause: The voltage in the power supply section is abnormal.

Supplementary information: The protection function worked due to a defect or overload in the power supply.
Turning on the power without correcting the abnormality will cause the protection function to work in 1 second and the
power supply will be shut off.

Notes:
• Applying the power to this unit without correcting the abnormality can be dangerous and cause additional cir-
RX-V685

cuit damage. To avoid this, if PS and DC protection function works 3 times consecutively, the power will not
turn on even when the MAIN ZONE z key is pressed. In order to turn on the power again, start up the self-
diagnostic function.
• The output transistors in each ampliﬁer channel should be checked for damage before applying power to this
unit.
• Ampliﬁer current should be monitored by measuring DC voltage across the emitter resistors for each channel.

2-4. When the protection function worked due to excessive heatsink/bridge diode (D1040) temperature.

TMPxPRT:xxx
xxx: A/D conversion value of voltage at the moment when the protection function worked
(Reference voltage: 3.3 V=255)

TMP1: Heatsink
TMP3: Bridge diode

Cause: The temperature of the heatsink/bridge diode (D1040) is excessive.

Supplementary information: The protection function worked due to the temperature limit being exceeded. Causes could
be poor ventilation or a defect related to the thermal sensor.
Turning on the power without correcting the abnormality will cause the protection function to work in 1 second and the
power supply will be shut off.

2-5. When the protection function worked due to excessive power supply voltage of USB.

USBPRT:xxx
Cause: The power supply voltage of USB is excessive.
If the power supply voltage of the USB device connected to the USB terminal is abnormal, USB Overloaded is displayed
and the protection function works and the power supply will be shut off.

30
RX-V685

2-6. When the protection function worked due to short between speaker terminals.

SPK PROTECT
Cause: Because of the speaker cables, etc., a short occurred between the speaker terminals, and excessive current
ﬂowed through the ampliﬁer.
Supplementary information: Use the same detection route as for the protection function due to excess current.
If excess current is detected after the speaker relay worked (ON), it is determined that there may be a short between the
speaker terminals.
Protection function works and the power supply will be shut off.
If the power supply is turned on again, CHECK SP WIRES will be displayed.

● History of protection function

When the protection function has worked, its history is stored in memory as backup data.
Even if no abnormality is noted while servicing the unit, an abnormality which has occurred previously can be deﬁned as
long as the backup data has been stored.

■ POWER AMPLIFIER ADJUSTMENT

1. Right after power is turned on, confirm that the voltage across the terminals of R1148 (SURROUND BACK Lch), R1149
(SURROUND BACK Rch), R1150 (FRONT Lch), R1151 (FRONT Rch), R1152 (CENTER), R1153 (SURROUND Lch) and
R1154 (SURROUND Rch) are within the confines of 0.1 mV to 10 mV.
2. If measured voltage exceeds 10 mV, remove R1100 (SURROUND BACK Lch), R1101 (SURROUND BACK Rch), R1102
(FRONT Lch), R1103 (FRONT Rch), R1104 (CENTER), R1105 (SURROUND Lch), R1106 (SURROUND Rch), and then
reconfirm the voltage.
Attention
If the measured voltage exceeds 10 mV after repairing the power amplifier, check other parts again for any possible
defect before removing the resistor.
3. Confirm that the voltage is within the confines of 0.2 mV to 15 mV after 60 minutes.

1 Safety measures
• Some internal parts in this product contain high voltages
and are dangerous. Be sure to take safety measures during
servicing, such as wearing insulating gloves.
• Note that the capacitors indicated below are dangerous
even after the power is turned off because an electric
charge remains and a high voltage continues to exist there.
Before starting any repair work, connect a discharging
OPERATION (2) (Side A) resistor (5 k-ohms/10 W) to the terminals of each capacitor
indicated below to discharge electricity. The time required
OPERATION (15) (Side A)
for discharging is about 30 seconds per each.
