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: A The power cables of the unit, TV and playback devices (such as BD players) are connected to AC wall outlets securely. B The unit, TV and playback devices (such as BD players) are turned on. C 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. Cause Remedy The auto power standby function worked. When the auto power standby function is enabled and one of the following conditions is met, the unit will automatically turn off. - No operations for 8 hours - No audio input and no operations for 20 minutes when BLUETOOTH is selected as the input source. Turn on the unit again. To stop the unit from turning off automatically, disable the auto power standby function (p.14). The protection circuitry has been activated. (The D indicator on the front panel of the unit flashes.) After confirming that all connections are made properly, turn on the unit again. If the power often suddenly turns off, unplug the power cable from the AC wall outlet and contact the nearest authorized Yamaha dealer or service center. Bluetooth connection is terminated on a Bluetooth device when the Bluetooth standby mode is enabled. Disable the Bluetooth standby mode (p.11). The protection circuitry has been activated three times consecutively. (If you try to turn on the power in this condition, the D indicator on the front panel of the unit flashes.) 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. All indicators go out although the unit is turned on (it may seem that the unit is turned off). The unit is not responding correctly. The unit operates by itself. The unit cannot be operated using the dedicated application "HOME THEATER CONTROLLER." (The screen of the application does not shift from the demo mode.) The brightness of indicators is set to off on the DIMMER key setting. The internal microcomputer is frozen, due to an external electric shock (such as lightning or excessive static electricity) or to a drop in the power supply voltage. Another Bluetooth device is being operated nearby. The Bluetooth device on which the application has been installed is not connected to the unit. Operate the DIMMER key to select the desired brightness (p.9). Hold down (power) on the front panel of the unit for more than 10 seconds to reboot it. (If the problem persists, unplug the power cable from the AC wall outlet and plug it again.) Terminate Bluetooth connection of the unit (p.11). Connect the Bluetooth device and the unit via Bluetooth and use the application. Audio Problem No sound. Cause Another input source is selected. The mute function is activated. The volume is too low. The power cable of the unit is not connected properly. Input jacks on both devices are connected. Signals that the unit cannot play back are being input. Remedy Select an appropriate input source (p.8). Cancel the mute function (p.9). Turn up the volume (p.8). Make sure that the power cable of the unit is connected to an AC wall outlet securely (p.6). Connect the input jack on the unit and the output jack on the external playback device. Change the digital audio output setting on the playback device to PCM or Dolby Digital. 16 En
