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.
