Ver 1.1

Notes on the AC power adaptor

Use only the AC power adaptor and USB
cradle supplied with the player. Do not use
any other AC power adaptor since this may
cause the player to malfunction.

The player is not disconnected from the
AC power source (mains) as long as it is
connected to the wall outlet, even if the
player itself has been turned off.

If you are not going to use the player for a
long time, be sure to disconnect the power
supply. To remove the AC power adaptor
from the wall outlet, grasp the adaptor plug
itself; never pull the cord.

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.

SERVICING NOTES

UNLEADED SOLDER

Boards requiring use of unleaded solder are printed with the lead­free 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.

• Replacement of CXR704060-201GA (IC1003),

MBM29SL800BE-90PBT (IC1101), S1R72003BOOA100
(IC2001), CXR710160-211GH (IC3001), CXD1616GH
(IC7001) and EDL1216CASA-10L-E (IC7002) used in this
set requires a special tool.

• Note for Printed Wiring Boards and Schematic Diagrams

Note on Printed Wiring Board:

• X : parts extracted from the component side.

• Y : parts extracted from the conductor side.

• f : internal component.

• : Pattern from the side which enables seeing.

(The other layers' patterns are not indicated.)

Caution:
Pattern face side: Parts on the pattern face side seen from
(Conductor Side) the pattern face are indicated.
Parts face side: Parts on the parts face side seen from
(Component Side) the parts face are indicated.

• MAIN and HDD boards are multi-layer printed board.
However, the patterns of intermediate-layer have not been in­cluded in diagram.

*Replacement of IC1003, 1101, 2001, 3001, 7001 and 7002

used in this set requires a special tool.

• Lead Layouts

surfac

Lead layout of conv entional IC CSP (chip size package)

Note on Schematic Diagram:

• All capacitors are in µF unless otherwise noted. (p: pF)
50 WV or less are not indicated except for electrolytics
and tantalums.

• All resistors are in Ω and 1/
specified.

• f : internal component.

• C : panel designation.

Note:

The components identi­fied by mark 0 or dotted
line with mark 0 are criti­cal for safety.
Replace only with part
number specified.

• A : B+ Line.

• Power voltage is dc 4.2 V and fed with regulated dc pow er

supply from CN9501.

• Voltages and waveforms are dc with respect to ground
under no-signal conditions.
no mark : PLAYBACK

• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal produc­tion tolerances.

• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal produc­tion tolerances.

• Circled numbers refer to waveforms.

• Signal path.

F : AUDIO

*Replacement of IC1003, 1101, 2001, 3001, 7001 and 7002

used in this set requires a special tool.

• The voltage and waveform of CSP (chip size package)
cannot be measured, because its lead layout is different
form that of conventional IC.
