Troubleshooting
Cause
The power cable is not connected or the
plug is not completely inserted.
The speaker impedance setting is
incorrect.
(When this unit is turned back on and
"CHECK SP WIRES!" is displayed.) The
protection circuitry has been activated
because this unit was turned on while a
speaker cable was shorted.
The internal microcomputer is frozen due
to an external electric shock (such as
lightning or excessive static electricity) or
by a drop in power supply voltage.
"Audio" in "1 HDMI" of Function Setup
is set to "TV."
A proper audio decoder is not selected.
Incorrect input or output cable
connections.
No appropriate input source has been
selected.
Speaker connections are not secure.
The volume is turned down or muted.
Signals this unit cannot reproduce are
being input from a source component,
such as a CD-ROM.
The HDMI components connected to this
unit do not support the HDCP copy
protection standards.
Remedy
Connect the power cable properly to an AC wall
outlet.
Set the speaker impedance to match your speakers.
Make sure that all speaker cables between this unit
and speakers are connected properly.
Disconnect the power cable from the AC wall outlet,
wait about 30 seconds and then plug it in again.
Select a choice for "Audio" (Function
Setup→1 HDMI→Audio) other than "TV."
Display the OPTION menu and set "Decoder Mode"
to "Auto."
Connect the cables properly. If the problem persists,
the cables may be defective.
Select an appropriate input source with NINPUT l
/ h or the gInput selection keys on the
remote control.
Secure the connections.
Turn up the volume.
Display Signal info of the option menu and check the
input signal format.
If "No Signal" is displayed, check if the playback
component is properly connected to this unit (or a
proper input source is selected).
If "___" is displayed, the input signal in that format
cannot be reproduced by this unit.
Connect HDMI components that support the HDCP
copy protection standards.
