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 the STANDBY indicator flashes
Immediately unplug the power cord, and check the
following item.
• If your system has a voltage selector, is the voltage
selector set to the correct voltage?
After the STANDBY indicator
stops flashing,
reconnect the power cord, and turn on the system. If
the issue persists, contact your nearest Sony dealer.
General
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 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 “STEREO” 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.
• Turn off nearby electrical equipment.
Tape deck
The sound exhibits excessive wow or flutter
or dropout.
• Clean the capstans and pinch rollers. Also, clean and
demagnetize the tape heads. See “Precautions” for details.
To improve tuner reception
Turn off CD player power by using the CD power
management function. By default, CD power is turned on.
Use buttons on the unit to turn off CD player power.
1
Press CD on the remote (or FUNCTION
repeatedly)
to select the CD function.
2
Press
to turn off the system.

After “STANDBY” stops flashing, press DISPLAY
to display the clock and then press
while holding down
on the unit.
“CD POWER OFF” appears. With CD player power
turned off, disc access time is increased. To turn on
CD player power, repeat the procedure until “CD
POWER ON” appears.
To reset the system to factory settings
If the system still does not operate properly, reset the
system to factory settings.
Use buttons on the unit to reset the unit to its factory
default settings.
1
Disconnect and reconnect the power cord, and
then turn on the system.

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 or multisession
• 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 socket,
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.
• 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.
To prevent a tape from being accidentally
recorded over
Break off the cassette’s overwrite protection tab from
side A or B as illustrated.
Break off the
cassette tab
To later reuse the tape for recording, cover the broken tab
with adhesive tape.
About a tape longer than 90 minutes
The use of the tape with more than 90 minutes of play
time is not recommended except for long, continuous
recording or playback.
Cleaning the tape heads
Use dry- or wet-type cleaning cassette (available
separately) after every 10 hours of use, before you start
an important recording, or after playing an old tape.
Failure to clean the tape heads can cause degraded sound
quality or an inability of the unit to record or play tapes.
For details, refer to the instructions of the cleaning
cassette.
Demagnetizing the tape heads
Use a demagnetizing cassette (available separately)
after every 20 to 30 hours of use. Failure to demagnetize
the tape heads can cause an increase in noise, a loss of
high frequency sound, and an inability to completely
erase tapes. For details, refer to the instructions of the
demagnetizing cassette.
