Troubleshooting
In general, refer any service problems to your Mark Levinson dealer. Before con-
tacting your dealer, however, check to see if the problem is listed here. If it is, try
the suggested solutions. If none of these solves the problem, contact your Mark
Levinson dealer.
1.
THE Nº30.5 WON’T FUNCTION, AND THE DISPLAY IS DARK.
✓
The standby button on the front panel isn’t turned on.
✓
The PLS-330 isn’t plugged into the AC mains.
✓
The center (digital) section of the Nº30.5 isn’t receiving DC from
the PLS-330 (double check the center section DC connection).
✓
The wall socket, adapter, or extension cord is faulty.
✓
There’s a tripped circuit breaker or blown fuse in the wall
outlet’s circuit.
✓
A fuse is blown in your PLS-330 (contact your Mark Levinson
dealer).
2.
THE DISPLAY IS LIT, BUT THERE IS NO OUTPUT
✓
The proper source isn’t selected on your Nº30.5.
✓
The proper source isn’t selected on your preamplifier.
✓
The interconnecting cables are connected incorrectly.
✓
The Left and Right towers of the Nº30.5 aren’t receiving DC from
the PLS-330 (double check their DC connections).
3.
THE Nº30.5 DISPLAY READS “NO DAS.”
✓
The selected digital source component is turned off.
✓
The digital connection between the digital source and the
Nº30.5 is faulty.
✓
The CD is inserted upside down in the CD transport.
4.
THE LINKED FUNCTIONS DON’T WORK.
✓
The Link cable is disconnected, or is connected incorrectly.
✓
The digital audio cable is disconnected, or is connected incor-
rectly (in which case the Linked function would work correctly,
but you might not be able to hear the results).
✓
Try turning off/disconnecting AC power from both the Nº31 and
the Nº30.5. After several seconds, restore AC power to the digital
processor,
then
turn on the Nº31’s
main power
switch.
✓
You may have older versions of the system software in your as-
sociated Mark Levinson components which do not fully support
all Linked functions. Contact your Mark Levinson dealer with the
model and serial numbers of your Mark Levinson components.
If needed, new EPROMs will be provided at no charge.
5.
THE DISPLAY FLASHES “RECORDING”
✓
The Record Link is preventing you from interrupting an active
digital record loop. Change the selected record input, or press
the function button twice. (See
Record link
, page 28.)
