Find your problem in the checklist below, and take 

the indicated corrective action.
If the issue persists, contact your nearest Sony dealer.

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.

 Is the power cord plugged in?

 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?

 Place the speakers as symmetrically as possible.

 Connect only the supplied speakers.

 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.

 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.

 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.

 Return to Normal Play by pressing PLAY MODE  

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

 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.

 Contact your Sony dealer or local authorized Sony 

service facility.

 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.

 Audio CD

 CD-R/CD-RW (audio data/MP3 files)

 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

 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.

 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 a qualified 

service shop.

 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.

 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.

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.

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.
