Appendix A Troubleshooting Guide
If the Casablanca III HD should function abnormally during operation, please review the items in the following
checklist. Please be sure to thoroughly check all other connected components such as speakers, amplifiers,
input devices (CD/LD transport, VCR, TV, etc.) as well as cables.
Symptom Possible Cause(s) Remedy
Mute on permanently. No Lock LED. Verify valid data at selected digital input.
No digital source connected. Verify that source is securely connected.
No power or front panel
lights and no sound. Power cable is not inserted 100% into IEC
connector. Ensure that the AC cord is inserted all the
way into the Casablanca III HD and that the
wall outlet is active.
Circuit breaker is open (AC outlet or
Casablanca III HD). Check the AC outlet circuit breaker and reset,
if necessary or contact your dealer.
No “LOCK” light. Defective or intermittent cable.
Verify that the digital cable is not defective by
checking the continuity, that both ends are
firmly connected. If possible, try a different
cable.
Digital source is not selected in the search
order. Toggle the A-D button until the jack name for
the desired source is displayed.
Defective source component. Verify that the source component is
functioning correctly and outputting valid
digital data.
Source component improperly connected. Ensure that the output cable from the source
component is connected to its active digital
output.
No audio output. No Lock LED. Verify valid data at selected input.
NOISE SEL activated with no speakers
selected. In the SETUP / INPUT / LEVELS submenu,
verify that the SOURCE parameter is set to
SOURCE ( A-D button).
Distortion from analog
input. Clipping. Adjust analog input level until the red clip LED
goes off.
No output from a
speaker. Speaker set to OFF or PHTM (Phantom). In the SETUP / INPUT / CONFIG submenu, set
the speaker to an appropriate parameter for
your system.
Low output from an
analog source. Analog input level set too low. Increase analog input level as high as
possible without clipping.
No Sub Woofer. SUB is set to 0 . Set the number of SUB s to reflect the current
speaker configuration in the SETUP / INPUT /
CONFIG submenu.
The currently selected MODE does not
support sub woofers.
Review the MODE Function section, detailed
on pages 47 – 49 to select a MODE that
functions for both the current input signal
format as well as the desired speaker or
system configuration.
No speakers are crossed over. Ensure that one or more speakers are
crossed over in the
SETUP / INPUT / CONFIG
submenu.
The current program material does not
contain an LFE track. N/A.
