Troubleshooting

Your Nēo ACE is a "smart" All-in-One that is equipped
with a self-diagnostic system that will automatically
shut itself down when it detects a problem. There are
ten (10) unique scenarios that can cause the ACE to
shutdown after displaying a diagnostic message. These
messages will help determine the exact cause of the
problem in case you have to contact a member of the
MOON support team. Error messages are shown for a
duration of ten (10) seconds; The blue LED will blink at
the same time. Then the ACE will go into "Standby"
mode. Here is a complete list of diagnostic messages,
each with a brief explanation:
"Incorrect Voltage on 1.3V
related to the DAC power supplies:
"Incorrect Voltage on 3.3V Unit will Shutdown" is related
to control logic and CPU power supplies:
"Incorrect Voltage on 5V Unit will Shutdown" Is related
to control logic supplies:
"Incorrect Voltage on 12V Unit will Shutdown" is related
to the main power supply:
"Incorrect Voltage on -15V Unit will Shutdown" and
"Incorrect Voltage on 15V Unit will Shutdown" are
related to the DAC and Preamplifier power supplies:
Unit will Shutdown" is
"Incorrect Voltage on -36V Unit will Shutdown" and
"Incorrect Voltage on 36V Unit will Shutdown" are
related to the power amplifier's power supplies.
"DC Detected on Output Unit will Shutdown" is related
to DC (direct current) coming from the source
component that you are currently listening to through
your ACE:
To confirm that there is DC present, first power down
the ACE via the main power rocker switch on the rear
panel; then disconnect the cables between the suspect
source component and the ACE. Next power up the
ACE via the main power rocker switch. Then attempt to
turn on your ACE again via the "Standby" button: A
successful power up will confirm that DC was coming
from this source; If power up is unsuccessful and/or you
still see the "DC Detected on Output
Shutdown" message, then consult your MOON retailer
for assistance.
"Temperature too high
to the ACE's operating temperature:
If your ACE reaches a dangerously high operating
temperature it will shutdown to avoid overheating
which can lead to physical damage inside the unit. You
will need to wait until the ACE cools down before
powering it up again. If this occurs repeatedly then
consult your MOON retailer for assistance.
If your ACE simply doesn't power up, turn off the main
power switch and check the AC fuse on the rear panel. If
the fuse appears good, put it back into its socket and
consult your dealer for assistance. If the fuse appears
blown, replace it with a fuse of the same size and rating.
Then turn on the main power switch. If your ACE still
doesn't power up, consult your MOON retailer for
assistance.
