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 Nº31.5 WON’T FUNCTION, AND THE DISPLAY IS DARK.
✓ The unit is is standby. Press the standby button.
✓ The Nº31.5 isn’t plugged into the AC mains or the main power
switch isn’t turned on.
✓ 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 Nº31.5 (contact your Mark Levinson
dealer).
2. THE DISPLAY IS LIT, BUT THERE IS NO OUTPUT
✓ The proper source isn’t selected on your digital processor.
✓ The proper source isn’t selected on your preamplifier.
✓ The interconnecting cables are connected incorrectly or are faulty.
3. THE Nº31.5 DISPLAY READS “NO DISC”
✓ There is no disc in the drawer for the transport to read.
✓ The disc is upside down and therefore cannot be read.
✓ The disc has loaded improperly and cannot be read—open the
drawer, ensure that the disc is placed properly in the drawer, and
try again.
4. THE Nº31.5 DISPLAY READS “NO DAMPER”
✓ There is no damper in the transport well; reopen the lid and
place the damper on the disc.
✓ The damper is incorrectly positioned; center it on the CD
spindle.
✓ The lid was interrupted before it could close, and therefore could
not sense the damper’s presence; remove the obstruction and al-
low the lid to close.
5. THE Nº31.5 WON’T PLAY A CD INSERTED IN THE PLAYER.
✓ The CD is inserted upside down. Be sure to insert it shiny side
down (label side up).
✓ There may be condensation (moisture) on the laser pickup. This
can happen if the Nº31.5 is moved from a cold environment
(such as a warehouse or a shipper’s truck) to a warm, humid one.
Set the main power switch to its "|" position, and leave it on for
at least one hour to warm up, then try playing a CD again.
6. WHEN A CD IS PLAYING, THE SOUND "SKIPS."
✓ The CD is severely scratched or dirty.
✓ The Nº31.5 is on an unstable surface or is too close to your
speakers.
