Factory Resetting Procedure
Firmware updating Procedure
Troubleshooting

ONKYO TX-NR545

Resetting the Unit

# How to reset:

Step:1

While holding down CBUSAT on the main unit (note that step 2 must be performed with this button pressed down)

Step:2

Press ONISTANDBY on the main unit. ("Clear" appears on the display and the unit returns to standby.)

# Do not unplug the power cord until "Clear" disappears from the display.

# How to reset the remote controller:

Step:1

While holding down RECEIVER on the remote controller, press Q until the remote indicator stays lit (about 3 seconds).

Step:2

Within 30 seconds, press RECEIVER again.

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.
