Troubleshooting

Before starting the procedure

Problems may be solved by simply turning the power

on/off or disconnecting/connecting the power cord,

which is easier than working on the connection,

setting and operating procedure. Try the simple

measures on both the unit and the connected

device. If the problem is that the video or audio is not

output or the HDMI linked operation does not work,

disconnecting/connecting the HDMI cable may solve

it. When reconnecting, be careful not to wind the

HDMI cable since if wound the HDMI cable may not fit

well. After reconnecting, turn off and on the unit and

the connected device.

The AV receiver turns off unexpectedly.

r The AV receiver will automatically enter standby mode

when Auto Standby is set and launched.

There’s no sound, or it’s very quiet.

r A wrong input selector button has been selected. Select

a correct input for the player. Also check that muting is

not on.

r Not all listening modes use all speakers.

There’s no picture.

r

A wrong input selector button has been selected.

r Video is not displayed if the listening mode is Pure Audio.

r To display video from the connected player on the TV

screen while the unit is in standby, you need to enable

HDMI Through function.

r When the TV image is blurry or unclear, power cord or

connection cables of the unit may have interfered. In

that case, keep distance between TV antenna cable and

cables of the unit.

r If you connect a player supporting HDCP2.2, be sure to

connect it to the HDMI IN3 jack of the unit. At the time,

connect the TV to the HDMI OUT MAIN jack.

HDMI control does not function correctly.

r Set the CEC link function of the unit to on. It is also

necessary to make the HDMI linked system setting on

the TV. See the TV's instruction manual for details.

The remote controller does not work.

r Be sure to press RCV first before operating the unit with

the remote controller.

There is no sound for multi-zone function.

r When you connect a CD player or such other player

without HDMI output jack, connect it to the analog audio

input jacks of the unit. Multi-zone output is not possible if

the connection is only with digital optical cable or digital

coaxial cable. In case of analog connection, analog audio

output setting may be necessary on the player.

Cannot access to network.

r Try plugging/unplugging the unit or the wireless LAN

router or check their power-on status. This will work well

in many cases.

r If the desired wireless LAN router is not in the access

point list, it may be set to hide SSID or the ANY

connection may be off. Change the setting and try again.

Bluetooth

r Try plugging/unplugging the unit and the Bluetooth-

enabled player. After that, check that the Bluetooth

function is enabled on the Bluetooth-enabled device and

the connection with the unit has been established.
