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.
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.
CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous
radiation exposure.

SECTION 1
SERVICING NOTE
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.
• In performing the repair with the power supplied to the set,
removing the MAIN board causes the set to be disabled.
In such a case, fix a convex 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. (See page 8)

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-4R)
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.

• Replacement of CDX2671-204GA (IC801) used in this set
requires a special tool.

OPTICAL PICK-UP FLEXIBLE BOARD
• On the set having the microcomputer version 1.000, some
adjusted values were set in the manual mode at the shipment,
but these data will be cleared when the NV is reset. Therefore,
on the set having the microcomputer version 1.000, change the
adjusted values following the Change of Adjusted Values
immediately after the NV was reset. (See page 18)
• If the nonvolatile memory was replaced on the set, the modified
program data must be written to the nonvolatile memory. In such
a case, write the modified data that meets the microcomputer
version following the patch data rewriting procedure at the
replacement of nonvolatile memory. (See page 23)

TEST MODE
4-1. Outline
4-3. Operation in Setting the Test Mode
• This set provides the Overall adjustment mode that allows CD
and MO discs to be automatically adjusted when in the test mode.
In this overall adjustment mode, the disc is discriminate between
CD and MO, and each adjustment is automatically executed in
order. If a fault is found, the system displays its location. Also,
the manual mode allows each individual adjustment to be automatically adjusted.
• Operation in the test mode is performed with the set. A key
having no particular description in the text, indicates a set key.
• For the LCD display, the LCD on the set is shown.
• When the test mode becomes active, first the display check mode
is selected.
• Other mode can be selected from the display check mode.
• When the test mode is set, the LCD repeats the following display.

For test mode set with the method 1:
Turn off the power and open the solder bridge on SL801 (TEST)
on the MAIN board.
Note: Remove the solders completely. Remaining could be shorted
with the chassis, etc.
For test mode set with the method 2:
Turn off the power.
Note: If electrical adjustment (see page 18) has not been finished
completely, always start in the test mode. (The set cannot

4-8. 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
1. Setting the test mode (see page 12).

Memory was Replaced
When the microcomputer in this set is replaced with a different
version of microcomputer, it is needed to initialize the modified
program data in the nonvolatile memory and write specific modified data for the new version in the memory.
If the microcomputer is replaced with a different version, the patch
data should be rewritten as performed when the nonvolatile memory
is replaced.
For a version where the method to write patch data is not described,
the modified data should be initialized as specified below:

Common 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 1/4 W or less unless otherwise
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.
Note:
Les composants identifiés par
une marque 0 sont critiques
pour la sécurité.
Ne les remplacer que par une
piéce portant le numéro
spécifié.
• A : B+ Line.
• Total current is measured with Minidisc installed.
• Power voltage is dc 3V and fed with regulated dc power
supply from external power voltage jack.
• Voltage and waveforms are dc with respect to ground
under no-signal conditions.
