TABLE OF CONTENTS
NOTES ON CHIP COMPONENT REPLACEMENT
• Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be dam-
aged by heat.
FLEXIBLE CIRCUIT BOARD REPAIRING
• Keep the temperature of 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.

SECTION 1
SERVICING NOTES
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 viscous (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.
NOTES ON HANDLING THE OPTICAL PICK-UP
BLOCK OR BASE UNIT
The laser diode in the optical pick-up block may suffer electro-
static 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 re
fl 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.
RELEASING THE DISC TRAY LOCK
The disc tray lock function for the antitheft of an demonstration
disc in the store is equipped.
Releasing Procedure:
1. Press the [
?/1
] button to turn the power on.
2. Press two buttons of [
x
] and [
Z
] for 5 seconds.
3. The message “UNLOCKED” is displayed on the
fl uorescent
indicator tube and the disc tray is unlocked.
Note: When “LOCKED”is displayed, the disc tray lock is not released by
turning power on/off with the [
?/1
] button.
NOTE OF REPLACING THE MOTOR BOARD
When the MOTOR board is damaged, exchange the entire
LOADING (BK) ASSY.
NOTE OF REPLACING THE IC107, Q1101, Q1102,
Q2101 AND Q2102 ON THE AMP BOARD
IC107, Q1101, Q1102, Q2101 and Q2102 on the AMP board can-
not exchange with single. When these parts are damaged, exchange
the entire mounted board.

PRECAUTIONS FOR DISASSEMBLY AND ASSEMBLY
Many of the internal parts in this unit use iron plates. Be careful not
to injure your hands while carrying out disassembly or assembly
procedures.
PRECAUTIONS FOR OPERATION CHECKS
If checking operations with the power on, be sure to connect the
GND wires (earth terminals) connected to the AMP board and
MAIN board to ground.
The units may fail to operate and parts may become damaged if
the GND wires are not connected properly. Be sure to connect the
GND wires before checking either board.
If the GND wire (earth terminal) is not long enough to reach when
the circuit board is removed, use alligator clips or a similar part to
extend the length to enable connection to ground.
