Power and system

Problem Cause Remedy

The power turns

off suddenly.

The auto power standby function

worked.

When the auto power standby

function is enabled and one of the

following conditions is met, the

sound bar 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 sound bar again. To stop

the sound bar from turning off

automatically, disable the auto power

standby function (p.15).

The protection circuitry has been

activated. (The D indicator on

the top panel of the sound bar

flashes.)

After confirming that all connections

are made properly, turn on the sound

bar again. If the power still turns off

suddenly or cannot be turned on,

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 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

D indicator on the top panel of the

sound bar 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

sound bar is

turned on (it may

seem that the

sound bar is

turned off).

The brightness of indicators is set

to off on the DIMMER key setting.

Operate the DIMMER key to select the

desired brightness (p.9).

The sound bar is

not responding

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 (power) on the rear

panel of the sound bar 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.)

The sound bar

operates by

itself.

Another Bluetooth device is being

operated nearby.

Terminate Bluetooth connection of the

sound bar (p.11).

TV’s 3D glasses

do not work.

The sound bar is blocking the 3D

glasses transmitter of your TV.

Check the position of the 3D glasses

transmitter of your TV and adjust the

position of the sound bar.

The sound bar

cannot be

operated using

the dedicated

application

“HOME

THEATER

(The screen of
