Troubleshooting

Problems may be caused by any component connected to this unit. Please check the table below, cross-referenc-
ing the instruction manuals for the other components.

The power to the system is not turned on.

• Make sure that the power cable is plugged into the AC

outlet.

• Unplug the power cable from the AC outlet, wait for

10 seconds or more, then plug the cable in again.

The power is turned off during the operation.

• If the SLEEP indicator is lit on the display, the Sleep

timer is functioning. Cancel the Sleep timer.
(See page 62.)

• The DVD receiver enters Standby mode after the timer

playback or recording is complete. (See page 65.)

• If the STANDBY indicator is blinking on and off, the

built-in protection circuit is activated. Be careful not
to short the positive and negative wires.

The DVD receiver turns itself on unexpectedly.

• The ACCUCLOCK function is updating the clock.

This is not a malfunction. You can turn off ACCU-
CLOCK. (See page 25.)

The sound is not heard.

• Make sure the power cable is plugged into an AC out-

let.

• Make sure that the speakers are connected correctly

and the speaker cables’ core wires touch only the
speaker connectors. (See page 18.)

• Check to make sure that the volume level is not set to

minimum. (See page 26.)

• Make sure that the input source is properly selected.
• Check to make sure the muting function is not

engaged.
If the MUTING indicator is flashing, the sound is
muted. Cancel the muting function. (See page 27.)

• When the headphones are connected, the speakers do

not output any sound. Disconnect the headphones.
(See page 27.)

Sound is not good.

• Make sure that the speaker cords are connected cor-

rectly. Check their polarity (+/–). (See page 18.)

• Connect the analog audio cables (RCA) firmly.

(See page 19.)

• Sound quality could be affected by a strong magnetic

field, such as a TV set. Locate such a device far from
the DVD receiver.

• If you have any devices that emit high intensity radio

waves near the DVD receiver, such as a cellular phone
in operation (calling), noise may be generated.

• The DVD receiver uses a rotating unit whose precision

instrument generates faint hissing sound while read-
ing a disc during playing back or searching a track;
you may hear it in a silent environment.

Sound breaks off due to vibration.

• The DVD receiver is designed for use as stationary

type; place it in a location with limited influence of
vibration.

Headphones makes noise or no sound.

• There may be a bad contact. Clean up the headphones

terminal. For information on how to clean up, see the
instruction manual attached to the headphones. Other-
wise, verify the cord of the headphones which may be
broken.

Sound Quality

• The sound quality becomes stable when 10 to 30 min-

utes have passed after the power was turned on. Using
cable ties to bundle audio cables with speaker cables
may degrade the audio performance, so don’t do it.

The disc won’t play or is automatically ejected after

loading.

• Make sure the disc is free from dirt and dust and is not

damaged. (See page 9.)

• Make sure the disc is loaded with the label side face-

up and aligned properly in the disc tray guide.

• Incompatible region number: If the region number on

a DVD-Video disc does not match the number on the
player, the disc cannot be used. (See page 74.)

• Condensation inside the player: Allow time for con-

densation to evaporate. Avoid using the player near an
air-conditioning unit.

• If the Parental Lock function is active, defeat it or

change the level. (See page 71.)
