Troubleshooting

1 Make sure the power cord and speaker

cords are correctly and firmly connected.

2 Find your problem in the checklist below,

and take the indicated corrective action.

If the issue persists, contact your nearest Sony

dealer.

If “PROTECT” appears on the

display

Immediately unplug the power cord, and

check the following items after “PROTECT”

disappears.

 Are the + and  speaker cords short-

circuited?

 Is anything blocking the ventilation holes of

the system?

After you have checked these above items

and found to be all right, reconnect the power

cord, and turn on the system. If the issue

persists, contact your nearest Sony dealer.

General

The system does not turn on.

 Is the power cord plugged in?

The system has entered standby mode

unexpectedly.

 This is not a malfunction. The system enters

standby mode automatically in about

30minutes when there is no operation or audio

signal output. See “To turn off the automatic

standby function.”

The clock setting or the Play Timer

operation has been cancelled

unexpectedly.

 If about a minute elapses with no operation,

the clock setting or Play Timer setting is

cancelled automatically. Perform the operation

again from the beginning.

There is no sound.

 Are the + and  speaker cords short-circuited?

 Are you using only the supplied speakers?

 Is anything blocking the ventilation holes of

the system?

 The specified station may have temporarily

stopped broadcast.

Sound comes from one channel, or the

left and right volumes are unbalanced.

 Place the speakers as symmetrically as

possible.

 Connect only the supplied speakers.

Severe hum or noise.

 Move the system away from sources of noise.

 Connect the system to a different wall outlet.

 Install a noise filter (available separately) to the

power cord.

The remote does not function.

 Remove any obstacles between the remote

and the remote sensor



on the unit, and

position the unit away from fluorescent lights.

 Point the remote at the system’s sensor.

 Move the remote closer to the system.

CD/MP3/WMA player

The sound skips, or the disc will not play.

 Wipe the disc clean, and replace it.

 Move the system to a location away from

vibration (for example, on top of a stable

stand).

 Move the speakers away from the system, or

place them on separate stands. At high volume,

speaker vibration may cause the sound to skip.

Play does not start from the first track.

 Set the play mode to normal play mode.

Starting playback takes more time than

usual.

 The following discs can increase the time it

takes to start playback;

 a disc recorded with a complicated tree

structure.

 a disc recorded in multisession mode.

 a disc that has not been finalized (a disc to

which data can be added).

 a disc that has many folders.

Tuner

Severe hum or noise, or stations cannot

be received.

 Connect the antenna properly.

 Try another place and orientation for better

antenna reception.

 Keep the antenna away from the speaker cords

and the power cord to avoid picking up noise.

 Turn off nearby electrical equipment.

Several radio stations can be heard at the

same time.

 Try another place and orientation for better

antenna reception.

 Bundle the antenna cable using commercially

available cord clips, for example, and adjust the

cable length.

DAB/DAB+ radio station is not received

properly.

 Check all antenna connections, then perform

the DAB Automatic Scan procedure (see

“Reception of DAB/DAB+ radio station”).

 The current DAB/DAB+ service may not be

available. Press PRESET+/PRESET



to select

a different service.

 If you have moved to another area, some

services/frequencies may have changed and

you may not be able to tune to your usual

broadcast.

Perform the DAB Automatic Scan procedure to

re-register the contents of broadcasts.

(Performing this procedure clears all previously

stored presets.)

To reset the system to factory

settings

If the system still does not operate properly, reset

the system to factory settings.

1 Disconnect and reconnect the power

cord, and then turn on the system.

2 Hold down 



on the remote and EQ

Precautions

Discs that this system CAN play

 Audio CD

 CD-R/CD-RW (audio data/MP3/WMA files)

Discs that this system CANNOT play

 CD-ROM

 CD-R/CD-RW other than those recorded in

music CD format, conforming to ISO9660 Level

1/Level 2 or Joliet

 CD-R/CD-RW recorded in multisession that

have not ended by “closing the session”

 CD-R/CD-RW of poor recording quality, CD-R/

CD-RW that have scratches or are dirty, or

CD-R/CD-RW recorded with an incompatible

recording device

 CD-R/CD-RW which is finalized incorrectly

 Discs containing files other than MPEG 1 Audio

Layer-3 (MP3)/WMA files

 Discs of non-standard shape (for example,

heart, square, star)

 Discs that have adhesive tape, paper, or sticker

attached to them

 Rental or used discs with attached seals where

the glue extends beyond the seal

 Discs that have labels printed using ink that

feels tacky when touched

Notes on discs

 Before playing, wipe the disc with a cleaning

cloth from the center out to the edge.

 Do not clean discs with solvents, such as

benzine, thinner, or commercially available

cleaners or anti-static spray intended for vinyl

LPs.

 Do not expose discs to direct sunlight or heat

sources such as hot air ducts, nor leave them in

a car parked in direct sunlight.

On safety

 Completely disconnect the power cord (mains

lead) from the wall outlet (mains) if it is not

going to be used for an extended period of

time. When unplugging the unit, always grip

the plug. Never pull the cord itself.

 Should any solid object or liquid get into the

system, unplug the system, and have it

checked by qualified personnel before

operating it again.

 The AC power cord can be changed only by a

qualified service facility.

On placement

 Do not place the system in an inclined position

or in locations that are extremely hot, cold,

dusty, dirty, or humid or lacking adequate

ventilation, or subject to vibration, direct

sunlight or a bright light.

 Be careful when placing the unit or speakers on

surfaces that have been specially treated (for

example, with wax, oil, polish) as staining or

discoloration of the surface may result.

 If the system is brought directly from a cold to

a warm location or is placed in a very damp

room, moisture may condense on the lens

inside the CD player, and cause the system to

malfunction. In this situation, remove the disc,

and leave the system turned on for about an

hour until the moisture evaporates.

On heat buildup

 Heat buildup on the unit during operation is

normal and is not cause for alarm.

 Do not touch the cabinet if it has been used

continuously at a high volume because the

cabinet may have become hot.

 Do not obstruct the ventilation holes.

On the speaker system

This speaker system is not magnetically shielded,

and the picture on nearby TV sets may become

magnetically distorted. In this situation, turn off

the TV, wait 15 to 30 minutes, and turn it back on.

If there is no improvement, move the speakers

far away from the TV.

Cleaning the cabinet

Clean this system with a soft cloth slightly

moistened with a mild detergent solution. Do not

use any type of abrasive pad, scouring powder,

or solvent, such as thinner, benzine, or alcohol.
