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 items.

• If your system has a voltage selector, is the voltage selector set to the correct voltage?
• Are you using only the supplied speakers?
• Is anything blocking the ventilation holes on the top or back of the system?

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

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.

• Press PLAY MODE repeatedly until both "PGM" and "SHUF" disappear to return to normal play.

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.

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 antenna away from the speaker cords and the power cord to avoid picking up noise.
• Connect a commercially available external antenna.
• Consult your nearest Sony dealer if the supplied AM antenna has come off the plastic stand.
• Turn off nearby electrical equipment.

To change the AM tuning interval
The AM tuning interval is factory-preset to 9 kHz (or 10 kHz, for some areas).
Use buttons on the unit to change the AM tuning interval.

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/CDRW 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 Layer3 (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 antistatic 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

• 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.
