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 Cause Remedy

The power turns off

suddenly.

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 NET 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.

Turn on the unit again. If the auto

power standby function is not

used, disable the function (p.29).

The protection circuitry has been

activated. (The STATUS indicator

flashes.)

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.

The power cannot be

turned on.

The protection circuitry has been

activated three times

consecutively. (If you try to turn on

the power in this condition, the

STATUS indicator will flash.)

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 configured so that

indicators do not glow or flash

unless the unit is being operated.

Use the DIMMER key to select

the desired brightness (p.15).

The unit does not

function correctly.

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.

Hold down the key on the unit

for more than 10 seconds to turn

on the unit. (If the problem

persists, unplug the power cable

from the AC wall outlet and plug it

again.)

The unit turns on by

itself.

Another Bluetooth device is being

operated nearby.

Terminate Bluetooth connection

with the unit (p.16).

The TV’s 3D glasses

do not work.

The unit is blocking the TV’s 3D

glasses transmitter.

Confirm the position of the TV’s

3D glasses transmitter, and

position the unit so that it does not

obstruct the transmitter.
