Optional components

There is no sound.

• Refer to General item “There is no sound.” on

page 47 and check the condition of the system.

• Connect the component properly (see page 45)

while checking:

– if the cords are connected properly.

– if the cord plugs are firmly inserted all the way.

• Turn on the connected component.

• Refer to the operating instructions supplied with

the connected component and start playing.

The sound is distorted.

• Set the volume of the connected component

lower.

The sound from the component connected to the

AUDIO IN MD (VIDEO) jacks is distorted.

• If “VIDEO” appears when you press

FUNCTION repeatedly, switch the function to

“MD” (see the tip for “Listening to audio from a

connected component” on page 46).

Tuner

Severe hum or noise/stations cannot be

received.

• Set the proper band and frequency (see page 33).

• Connect the antenna properly (see page 9).

• Find a place and an orientation that provide good

reception, then set up the antenna again. If you

cannot obtain good reception, we recommend

you connect a commercially available external

antenna.

• The supplied FM lead antenna receives signals

along its entire length, so make sure you extend

it fully.

• Locate the antennas as far away from the speaker

cords as possible.

• Consult your nearest Sony dealer if the supplied

AM antenna has come off the plastic stand.

• Try turning off surrounding electrical

equipments.

A stereo FM program cannot be received in

stereo.

• Press REPEAT/FM MODE until “STEREO”

appears in the display.

If the system still does not operate

properly after performing the above

measures, reset the system as

follows:

1 Disconnect the mains lead.

2 Reconnect the mains lead.

3 Press ?/1 to turn on the system.

4 Press ?/1 while pressing x and z REC.

The system is reset to the factory settings

except for DVD settings. You should set the

settings you made, such as the preset stations,

clock, and timer.

To reset the DVD settings, select “RESET” in

step 3 of “Using the Setup Display” (page 19).

After you select “RESET” and press ENTER,

select “YES”, then press ENTER to reset the

settings (it takes a few seconds to complete).

Do not press ?/1 when resetting the system.
