Troubleshooting

In general, refer any service problems to your Mark Levinson dealer. Before contacting 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 Nº390S won’t function, and the display is dark.

The unit is in standby. Press the standby button.

The Nº390S 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 Nº390S (contact your Mark Levinson dealer).

2.The display is lit, but there is no output.

The proper digital input isn’t selected on the Nº390S.

The proper analog input isn’t selected on your preamplifier.

The interconnecting cables are connected incorrectly or are faulty.

The variable output volume adjustment is set to 0.0 (off).

3.The Nº390S 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 Nº390S won’t play a CD inserted in the player.

The CD is inserted upside down.

There may be condensation (moisture) on the laser pickup. This can happen if the Nº390S is moved from a cold environment (such as a warehouse or a shipper’s truck) to a warm one. Set the main power switch to its "" position, and leave it on for one hour to warm up, then try playing a CD again.
