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 on the top

or back 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?

There is no sound.

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

 Are you using only the supplied speakers?

 Is anything blocking the ventilation holes on the top or

back of the system?

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 socket.

 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 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.

 Return to Normal Play by pressing PLAY MODE 

repeatedly until both “PGM” and “SHUF” disappear.

Starting playback takes more time than usual.

 The following discs take a longer time 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.

The disc tray does not open and “LOCKED”

appears.

 Contact your Sony dealer or local authorized Sony

service facility.

Tuner

Severe hum or noise, or stations cannot be

received. (“TUNED” or “ST” flashes on the

display.)

 Connect the antenna properly.

 Find a location and an orientation that provide good

reception, and then set up the antenna again.

 Keep the antennas away from the speaker cords and the

power cord to avoid picking up noise.

 Turn off nearby electrical equipment.

Precautions

Discs that this system CAN play

 Audio CD

 CD-R/CD-RW (audio data/MP3 files)

Discs that this system CANNOT play

 CD-ROM

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

format or MP3 format conforming to ISO9660 Level 1/

Level 2, 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) 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 it in a car parked in

direct sunlight.

On safety

 The unit is not disconnected from the AC power source

(mains) as long as it is connected to the wall outlet,

even if the unit itself has been turned off.

 Completely disconnect the power cord (mains lead)

from the wall socket (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.

 AC power cord must be changed only at the qualified

service shop.

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.
