Design and specifications are subject to change

without notice

Notes on chip component replacement

•Never reuse a disconnected chip component.

•Notice that the minus side of a tantalum capacitor may be

damaged by heat.

Flexible Circuit Board Repairing

•Keep the temperature of the soldering iron around 270 ˚C

during repairing.

•Do not touch the soldering iron on the same conductor of the

circuit board (within 3 times).

•Be careful not to apply force on the conductor when soldering

or unsoldering.

CAUTION

Use of controls or adjustments or performance of procedures

otherthan thosespecifiedhereinmay result inhazardous radiation

exposure.

UNLEADED SOLDER

Boards requiring use of unleaded solder are printed with the lead-

free mark (LF) indicating the solder contains no lead.

(Caution: Some printed circuit boards may not come printed with

the lead free mark due to their particular size)

: LEAD FREE MARK

Unleaded solder has the following characteristics.

•Unleaded solder melts at a temperature about 40 °C higher

than ordinary solder.

Ordinary soldering irons can be used but the iron tip has to be

applied to the solder joint for a slightly longer time.

Soldering irons using a temperature regulator should be set to

about 350 °C.

Caution: The printed pattern (copper foil) may peel away if

the heated tip is applied for too long, so be careful!

•Strong viscosity

Unleaded solder is more viscou-s (sticky, less prone to flow)

than ordinary solder so use caution not to let solder bridges

occur such as on IC pins, etc.

•Usable with ordinary solder

It is best to use only unleaded solder but unleaded solder may

also be added to ordinary solder.

SAFETY-RELATED COMPONENT WARNING!!

COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINE

WITH MARK 0ON THE SCHEMATIC DIAGRAMS AND IN

THE PARTS LIST ARE CRITICAL TO SAFE OPERATION.

REPLACE THESE COMPONENTS WITH SONY PARTS WHOSE

PART NUMBERS APPEAR AS SHOWN IN THIS MANUAL OR

IN SUPPLEMENTS PUBLISHED BY SONY.

You can play back the following discs on this

system. Other discs cannot be played back.

List of playable discs

Discs that this system cannot

play

•An8 cm disc

•An8 cm disc converted to a standard disc

using an adaptor

•CD-ROMs

•CD-Rs/CD-RWs other than those recorded in

the following formats:

–music CD format

–MP3format that conforms to ISO9660

1)

Level 1/Level 2, Joliet or Multi Session

2)

•Adiscthat has a non-standard shape (e.g.,

card, heart).

•Adiscwithpaper or stickers on it.

•Adisc that has the adhesive, cellophane tape,

or a sticker still left on it.

1)

ISO9660 Format

The most common international standard for the

logical format of files and folders on a CD-ROM.

There are several specification levels. In Level 1,

file names must be in the 8.3 format (no more than

eight characters in the name, no more than three

characters in the extension “.MP3”) and in capital

letters. Folder names can be no longer than eight

characters. There can be no more than eight nested

folder levels. Level 2 specifications allow file

names and folder names up to 31 characters long.

Each folder can have up to 8 trees.

For Joliet in the expansion format (file and folder

names can have up to 32 characters), make sure of

the contents of the writing software, etc.

2)

Multi Session

This is a recording method that enables adding of

data using the Track-At-Once method.

Conventional CDs begin at a CD control area called

the Lead-in and end at an area called Lead-out. A

Multi Session CD is a CD having multiple sessions,

with each segment from Lead-in to Lead-out

regarded as a single session.

(audio data/MP3 files)

Notes on CD-R and CD-RW

•SomeCD-Rs or CD-RWs cannot be played

on this system depending upon the recording

quality or physical condition of the disc, or

the characteristics of the recording device.

Furthermore,thediscwillnotplayifithas not

been correctly finalized. For more

information, see the operating instructions for

the recording device.

•Discsrecorded on CD-R/CD-RW drives may

not be played back because of scratches, dirt,

recording condition or the driver’s

characteristics.

•CD-RandCD-RW discs recorded in multi-

session that have not ended by “closing the

session” are not supported.

•Thesystem may be unable to play MP3

format files that do not have the “.MP3”

extension.

•Attempting to play non-MP3 format files that

havethe“.MP3”extensionmayresultinnoise

or malfunction.

•Withformats other than ISO9660 level 1 and

2, folder names or file names may not be

displayed correctly.

•Thefollowing discs take a longer time to start

playback.

–adiscrecorded with complicated tree

structure.

–adisc recorded in Multi Session.

–adisctowhich data can be added (non-

finalized disc).

Music discs encoded with

copyright protection

technologies

This product is designed to playback discs that

conform to the Compact Disc (CD) standard.

Recently, various music discs encoded with

copyright protection technologies are marketed

by some record companies. Please be aware that

among those discs, there are some that do not

conform to the CD standard and may not be

playable by this product.

Cautions when playing a disc

that is recorded in Multi

Session

•Ifthediscbegins with a CD-DA session, it is

recognized as a CD-DA (audio) disc, and only

the first session will be played back.

•Ifthe disc begins with an MP3 session, it is

recognized as an MP3 disc, and playback

continues until a CD-DA (audio) session is

encountered.

•Theplayback range of an MP3 disc is

determined by the tree structure of files

produced by analyzing of the disc.

•Adiscwitha mixed CD format will be

recognized as a CD-DA (audio) disc.

•Data part of CD-Extras

1)

•Audiopart of Mixed CDs

2)

1)

CD-Extra: This format records audio (audio CD

data) on the tracks in session 1 and data on the tracks

in session 2.

2)

Mixed CD: This format records data on the first

track and audio (audio CD data) on the second and

subsequent tracks of a session.

MODEL PART No.

Chilean and Peruvian models 4-254-166-1[]

AEP and UK models 4-254-166-2[]

The laser diode in the optical pick-up block may suffer electrostatic

break-down because of the potential difference generated by the

charged electrostatic load, etc. on clothing and the human body.

During repair, pay attention to electrostatic break-down and also

use the procedure in the printed matter which is included in the

repair parts.

The flexible board is easily damaged and should be handled with

care.

NOTES ON LASER DIODE EMISSION CHECK

The laser beam on this model is concentrated so as to be focused on

the disc reflective surface by the objective lens in the optical pick-

up block. Therefore, when checking the laser diode emission,

observe from more than 30 cm away from the objective lens.

LASER DIODE AND FOCUS SEARCH OPERATION

CHECK

Carry out the “S curve check” in “CDsection adjustment” and check

that the S curve waveforms is output three times.
