Cause
The connected component is not set to
output the desired digital audio signals.
Incorrect cable connection.
A DTS-CD is being played back.
"Memory Guard" in "Setup Menu" is set
to "On."
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.
Speaker cables are short-circuited.
This unit is too close to other digital or
radio frequency equipment.
The video software is copy-protected.
The internal temperature becomes too
high and the overheat protection circuitry
has been activated.
Cause
The number of the connected HDMI
components is over the limit.
The connected HDMI component does not
support high-bandwidth digital copyright
protection (HDCP).
Remedy
Set the playback component properly referring to its
operating instructions.
Connect the audio cables properly. If the problem
persists, the cables may be defective.
1) When only noise is output
If a DTS bitstream signal is not properly input to this
unit, only noise is output. Connect the playback
component to this unit by digital connection and play
back the DTS-CD. If the condition is not improved,
the problem may results from the playback
component. Consult the manufacturer of the playback
component.
2) When noise is output during playback or skip
operation
Before playing back the DTS-CD, display the option
menu after selecting the input source and set
"Decoder Mode" to "DTS."
Set "Memory Guard" to "Off."
Disconnect the power cable from the AC wall outlet,
wait about 30 seconds and then plug it in again.
Make sure all speaker cables are connected correctly.
Move this unit further away from such equipment.
Wait about 1 hour for this unit to cool down and then
turn it back on.
Remedy
Disconnect some of the HDMI components.
Connect an HDMI component that supports HDCP.
