■ TO SERVICE PERSONNEL
1. Critical Components Information
Components having special characteristics are marked ⚠ and
must be replaced with parts having specifications equal to those
originally installed.
2. Leakage Current Measurement (For 120V Models Only)
When service has been completed, it is imperative to verify
that all exposed conductive surfaces are properly insulated
from supply circuits.
• Meter impedance should be equivalent to 1500 ohms shunted
by 0.15 F.
For U model
“CAUTION”
“F3702: FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ONLY WITH SAME TYPE 8A,
125V FUSE.”
For C model
CAUTION
F3702: REPLACE WITH SAME TYPE 8A, 125V FUSE.
ATTENTION
F3702: UTILISER UN FUSIBLE DE RECHANGE DE MÉME TYPE DE 8A, 125V.
WALL
OUTLET
• Leakage current must not exceed 0.5mA.
• Be sure to test for leakage with the AC plug in both polarities.

About lead free solder
RX-V673/HTR-6065/
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
repair 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.

■ 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
indicated below to discharge electricity.
The time required for discharging is about 30 seconds per each.
C1082–C1085 on MAIN P.C.B.

■ UPDATING FIRMWARE
When the following parts are replaced, the firmware must be updated to the latest version.
DIGITAL P.C.B.
FPGA Flash ROM: IC77 on DIGITAL P.C.B.
DSP(TI) Flash ROM: IC923 on DIGITAL P.C.B.
NETWORK Flash ROM: IC953 on DIGITAL P.C.B.
● Confirmation of firmware version and checksum
Before and after updating the firmware, check the firmware version and checksum by using the self-diagnostic
function menu.
Start up the self-diagnostic function and select “S4. ROM VERSION/CHECKSUM” menu.
Using the sub-menu, have the firmware version and checksum displayed, and note them down.
(See “SELF-DIAGNOSTIC FUNCTION”)
* When the firmware version is different from written one after updating, perform the updating procedure again from
the beginning again.
● Initializing the back-up IC (EEPROM: IC82 on DIGITAL P.C.B.)
After updating the firmware, the back-up IC MUST be initialized by the following procedure to store the setting
information (soundfield parameters, system memory and tuner presetting, etc.) properly.
Start up the self-diagnostic function and select “S3. FACTORY PRESET” menu. (See “SELF-DIAGNOSTIC FUNCTION”)
Select “PRESET RSRV”, press the “MAIN ZONE
the back-up IC is initialized.
● Required Tools
• USB storage device
• Firmware
● Preparation
