SECTION  1
SERVICING  NOTES
NOTES  ON  HANDLING  THE  OPTICAL  PICK-UP  
BLOCK  OR  BASE  UNIT
The laser diode in the optical pick-up block may suffer electrostat-
ic 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 fl exible 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 refl ective surface by the objective lens in the optical 
pickup block. Therefore, when checking the laser diode emission, 
observe from more than 30 cm away from the objective lens.
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 fl ow) 
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.
About the Hard Disk Drive
Because of its high storage density, the hard disk can read and
write data a very high speeds.
It is, however, easily damaged by mechanical vibration, shock, or
dust. Although the hard disk is equipped with safety mechanisms
to prevent the lost of data due to these factors, the following
precautions should be taken during the handling of the  unit.
• Do not subject the  unit to strong shocks or vibrations.
• Do not place the unit in a location subject to mechanical
vibration or at an unstable location.
• Do not move the unit while the power cord is connected to a 
wall outlet.
• Do not disconnect the power cord while the unit is recording or
playing a track.
• Do not use the unit in a place subject to extreme changes in 
temperature (a temperature gradient greater than 18°F (10°C)/
hour).
• Do not attempt to replace or upgrade the hard disk drive by
yourself, as this may cause the unit to malfunction.
Sony cannot provide compensation for any loss of data caused by a 
damaged hard disk drive.
On data back up
Audio data and system settings stored on the unit’s hard disk may
be lost during repairs done to the unit. Before taking the unit in for 
repairs, it is recommended that you record the settings on a piece
of paper and that you use the Back Up function to back up the data 
to a shared folder on your computer or a USB hard disk drive (see
“Backing up and restoring audio data” on page 104).
Data on the unit’s HDD is subject to damage during normal
operations. To prevent the loss of data, you should back up the data 
on a regular basis. Please note that we cannot take responsibility
for any data that may be lost or
repairs.
Cleaning the cabinet
detergent solution. Do not use any type of abrasive pad, scouring
powder, or solvent, such as thinner, benzine, or alcohol.
Note on the power cord
Before you unplug the power cord from the wall outlet, make sure
that the unit is in standby mode (the On/Standby indicator is lit up 
red or orange). If you unplug the power cord while the unit is
operating (the On/Standby indicator lit up green), data that was
recorded may be lost or the unit may malfunction.

Notes on CDs
v
 Do not scratch or attach stickers to the surface of the disc.
v
 CDs with non-standard shapes (e.g., a star, heart, or square)
cannot be played on this unit. Attempting to do so may damage
the unit.
v
 When cleaning the disc, use a cleaning cloth and wipe the disc
from the center out to the edge. If the disc is extremely dirty,
wipe the disc with a slightly moistened cloth, followed by a dry
cloth. Do not clean a disc with a benzine thinner, commercial
cleaners or anti-static sprays intended for vinyl LPs.
v
 Do not place discs in hot places, including places exposed to
direct sunlight, near heat sources such as hot air ducts, or inside
parked cars.
v
 Do not use a rental or second-hand disc on which glue that
spread from under the label attached to it. If you do, there is a 
chance that the disc may become stuck to parts within the unit,
causing it to malfunction.
v
 Do not use a commercial cleaning disc as it may cause the unit
to malfunction.
Music discs encoded with copyright protection technologies
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.
Note on DualDiscs
A DualDisc is a two sided disc product which mates DVD
recorded material on one side with digital audio material on the
other side. However, since the audio material side does not conform 
to the Compact Disc (CD) standard, playback on this product is
not guaranteed.

Notes
v
 If the disc begins with a CD-DA (or “ATRAC”/MP3) session, it
is recognized as a CD-DA (or “ATRAC”/MP3) disc, and other
sessions are not played back.
v
 A disc with a mixed CD format is recognized as a CD-DA
(audio) disc.
v
 Some CD-Rs or CD-RWs may not be played on this unit,
depending on its characteristics and the recording conditions.
v
 CD-RWs may require some time
is because they have a lower
of discs.
v
 In the case of discs containing more than 500 tracks of audio
data, the unit will not recognize track 501 or above.
v
 Discs with many directories or a complicated structure may
require some time before they start playing. When recording
albums to a disc, it is recommended that recording will be done
no deeper than the sub-directory 2 level.

HOW  TO  DRAW  OUT  FORCIBLY  THE  DISC  TRAY
In the event that the disc tray does not come out due to any fail-
ure, three methods are available to draw it out forcibly. Use either 
method described below according to the symptom.
METHOD  1
If the power did not turn on or if the power is OFF:
1.  With the power cord unplugged, remove the panel (side L) / 
(side R) assembly, panel (top), and panel (front). (See “How to 
Remove 2-2, 2-3 (page 8), 2-6 (page 10)”)
2.  As shown in the fi gure, insert a thin rod into the hole at the 
lower part of CD block, and push it in the arrow A direction.

Peel the cushion (CD) a 
little when it hides the hole.
METHOD  2
If the CD-ROM drive is turned on but the mother board does not 
start:
1.  Insert a thin fl at-tip screwdriver into a round hole at the bottom 
of the set.
2.  Through a hole at the bottom of CD-ROM drive, short the 
points (patterns) on the board of CD-ROM drive.

METHOD  3
If the mother board starts but the system software is abnormal:
Plug in the power cord while pressing the [Z] button.
Note: This method is same as “CD Start Mode” of test modes. Load the 
start disc and close the disc tray, and if the start disc is not recog-
nized, start the CD as usual.
