Troubleshooting

Refer to the table below when the unit does not function properly. If the problem you are experiencing is not listed below or if the instructions
below do not help, turn off the unit, disconnect the power cable, and contact the nearest authorized Yamaha dealer or service center.
First, check the following:
1 The power cables of the unit, TV and playback devices (such as BD/DVD players) are connected to AC wall outlets securely.
2 The unit, TV and playback devices (such as BD/DVD players) are turned on.
3 The connectors of each cable are securely inserted into jacks on each device.
Power and system
Problem
The power turns off
suddenly.
The power cannot be turned
on.
All indicators go out although
the unit is turned on (it may
seem that the unit is turned
off).
Cause
When the auto power standby function is enabled, the unit
automatically turns off in any of the following situations:
- No operations have been performed for 8 hours
- BLUETOOTH or HDMI is selected as the input source,
but no audio has been input to the unit or no operations
have been performed with the unit for more than 20
minutes.
The protection circuitry has been activated.
(The DD / DTS indicator flashes.)
The Bluetooth connection was terminated by a Bluetooth
device with the unit's Bluetooth standby function enabled.
The protection circuitry has been activated three times
consecutively. (If you try to turn on the power in this
condition, the DD / DTS indicator will flash.)
The unit is configured so that indicators do not glow or
flash unless the unit is being operated.
Remedy
Turn on the unit again. If the auto power standby function is not
used, disable the function (p. 32).
After confirming that all connections are made properly, turn on
the unit again. If the power still turns off frequently, unplug the
power cable from the AC wall outlet and contact the nearest
authorized Yamaha dealer or service center.
Disable the Bluetooth standby function (p. 30).
To protect the product, the power cannot be turned on. Unplug
the power cable from the AC wall outlet and contact the nearest
authorized Yamaha dealer or service center.
Use the DIMMER key to select the desired brightness (p. 25).
