Self-diagnostics
This function is For avoiding the rupture of electrolytic
capacitors with amplifier circuit failure during power-ON.
Operation
of Self—diagnostic
Self-diagnostic will start at the timing of next power on,
after goes to the protect mode by Current detection or DC voltage detection.
Only On/Standby key could work in this mode. Also remote
control does not work.
However, the CLEAR operation is enabled.
During Self-diagnostic, the power supply for amplifier
circuit become low voltage state(SEC1-LOW), and the speaker relay will be
turned off. Then, MPU will check each amplifier circuits internally by entering
the test signal (20 kHz,-20 dBFS sine wave) to each channel from DSP.
MPU will judge the amplifier circuit is good or not from
VOLH value.
The normal range of VOLH value is 0.04 V < VOLH <
0.20 V.
If VOLH value is in the out of this range, it will be
judged as NG (No good).
No
problem found
When protected by current detection, and no problem
found, "CHECK SP WIRE“ will be displayed in this State, Only the On/Standby
key is effective. And it do not anything for 3 minutes, unit goes into stand by
automatically.
When protected by a DC voltage detection, and no problem
found, unit goes into normal operation.
Problem
found
When judged as there is a problem on any channel, the
information of channel that has a problem will be displayed. In this State, Only
the On/Standby key is effective. Also remote control does not work. if do not anything
for 3 minutes, unit goes into standby automatically. This state will keep also
after unit turn on/off, or AC unplugged.
The power supply for the amplifier becomes low voltage
state and the speaker relay will be turned on.
Repair
Process and How to Confirm
Confirmation
of the protect cause
While NG channel is displayed, You can confirm the
protect cause by following the step below
1. Press the Enter button
2. The protect cause are displayed for 5 seconds.
Please check the around of those amplifier circuit and
repair it.
Clear
of NG CH information
After repair, you can clear NG CH information by
following the steps below.
1. Press the On!Standby key while pressing the Enter key.
2. Display as in the right figure appears.
3. Unit goes into Standby automatically after 5 seconds.
Self-diagnostic will start again at the timing of next
power on.
By this, You can verify whether repair was properly or
not.
If problem found after repair, please re-check the around
of its circuit.
Cancel
of Self-diagnostic
You can cancel this mode by clear operation (press
Standby key while pressing CBL/SAT key)
After cancel this mode, receiver will be started as
normal operation.
How
to check Firmware Version & Preparation of Update

Preparation
of Update
1. Connect the USB storage device to your PC. If there is
any data in the USB storage device, remove it.
2. Download the firmware file (package file) from the Onkyo
FTP-server.
However European service partners should download the firmware
file (package file) from the ExtraNet.
Onkyo FTP-server: onkyo.co.jpf_servicefwalTX-NR545
ID and Password are those we informed when changed.
Filename is as follows: ON KAVROO1 D_****************.zip
Unzip the downloaded file. A following file is created.
ONKAVROO1 D_************.of1
ONKAVROO1 D_************.of2
ONKAVROO1 D_************.of3
ONKAVROO1 D_************.of4
ONKAVROO1 D_************.of5
3. Copy it to the USB storage device. Be careful not to
copy the zip file
4. Remove the USB storage device from your PC.
How
to update (service mode)
Overwriting is also possible.
