Bose L1 I Troubleshooting

Troubleshooting – Preset Update Process for L1™ model I systems
Symptom
I'm playing an
upgrade disc from the
DVD player, but the
power LED on the
power stand does not
blink.
Red LED
Cause
The DVD player is not actually
playing the disc.
Data is not yet streaming into the
power stand.
The DVD player is not connected to
the power stand.
The digital audio output setting on
the DVD player is set to the wrong
output format.
The digital audio output is altered by
other "sound-enhancing" settings on
the DVD player.
The RCA patch cable is damaged.
The power stand was sent
Resolution
Ensure that the DVD
player is playing the disc
by viewing the
incrementing playback
time on the DVD display.
Make sure PAUSE is not
on.
Wait at least 10 seconds
of playback to witness
the LED blinking on the
power stand after the
disc begins to play.
Connect a RCA patch
cable from the DVD
player's coaxial digital
audio output to the
power stand Data IN
jack.
With a TV connected,
check the menu options
of the digital audio
output connection.
Sometimes an option for
Bitstream or PCM is
available. Bitstream
should be selected on
most players. If
Bitstream does not
work, then try PCM or
other available options.
With a TV connected,
check the menu options
for audio output. Some
players offer 3D,
normalization, and
compression settings.
All of these should be
turned off.
Try another good-quality
RCA cable.
Reboot the power stand
