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.

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

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

• Strong viscosity
Unleaded solder is more viscous (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.

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 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

Never look into the laser diode emission from right above when
checking it for adjustment. It is feared that you will lose your sight.

NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK
(LCX-5R)

The laser diode in the optical pick-up block may suffer electro­static break-down easily. When handling it, perform soldering
bridge to the laser-tap on the flexible board. Also perform mea­sures against electrostatic break-down sufficiently before the op­eration. The flexible board is easily damaged and should be handled
with care.

In such a case, fix a conve x part of the open/close detect switch
(S806 on MAIN board) with a tape in advance.
Handle the FLEXIBLE board (overwrite head) with care, as it
has been soldered directly to the MAIN board.
In repairing the component side of MAIN board, connect the
FLEXIBLE board (overwrite head) and the MAIN board with
the lead wires in advance.

• Replacement of CXD2677-202GA (IC801) used in this set re­quires a special tool.

• The shipment data will be cleared when the NV is reset. There­fore, change the NV adjusted values following the Change of
NV Adjusted Values immediately after the NV was reset. (See
page 19)

SELF-DIAGNOSIS RESULT DISPLAY MODE

This set uses the self-diagnostic function system in which if an
error occurred during the recording or playing, the mechanism
control block and the power supply control block in the micro­computer detect it and record its cause as history in the nonvola­tile memory.
By checking this history in the test mode, you can analyze a fault
and determine its location.
Total recording time is recorded as a guideline of how long the
optical pickup has been used, and by comparing it with the total
recording time at the time when an error occurred in the self­diagnosis result display mode, you can determine when the error
occurred.
Clear both self-diagnosis history data and total recording time, if
the optical pickup was replaced.

• Self-Diagnosis Result Display Mode Setting Method

6-4. NOTE FOR PRINTED WIRING BOARD AND SCHEMATIC DIAGRAMS

e

MZ-N505

Note on Printed Wiring Board:

• X : parts extracted from the component side.

• Y : parts extracted from the conductor side.

• : 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 par ts face side seen from
(Component Side) the parts face are indicated.

• MAIN board is four-layer printed board.
However, the patterns of layers 2 and 3 have not been
included in this diagrams.

* Replacement of IC801 used in this set requires a spe-

cial tool.

• Lead Layouts

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

surfac

Note on Schematic Diagram:

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

• All resistors are in Ω and 1/
specified.

• % : indicates tolerance.

• 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.

• Total current is measured with MD installed.

• Power v oltage is dc 3 V and fed with regulated dc power
supply from DC IN 3 V jack (J601).

• Voltages and wa v eforms are dc with respect to ground in
playback mode.

• Voltages are taken with a V OM (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.

* Replacement of IC801 used in this set requires a spe-

cial tool.

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