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.
SAFETY-RELATED COMPONENT WARNING!
COMPONENTS IDENTIFIED BY MARK 0OR DOTTED LINE
WITH MARK 0ON THE SCHEMATIC DIAGRAMS AND IN
THE PARTS LIST ARE CRITICAL TO SAFE OPERATION.
REPLACE THESE COMPONENTS WITH SONY PARTS
WHOSE PART NUMBERS APPEAR AS SHOWN IN THIS
MANUAL OR IN SUPPLEMENTS PUBLISHED BY SONY.
This appliance is classified as
a CLASS 1 LASER product.
This marking is located on the
rear exterior.
CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous radia-
tion exposure.

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.
ABOUT THE REMOTE COMMANDER USED IN THE
SERVICE MODE
When the service mode is operated, the following, remote com-
mander is necessary.
(The service mode cannot be operated by remote commander to
which this machine is attached)
Remote commander (RM-ASP004): Part No. 1-479-272-21
Note: Above-mentioned remote commander is one example. If it is the
one printed under a remote commander as “DVD”, any remote com-
mander can be operated.
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.

TEST MODE
When the service mode is operated, the following, remote com-
mander is necessary.
(The service mode cannot be operated by remote commander to
which this machine is attached)
Remote commander (RM-ASP004): Part No. 1-479-272-21
Note: Above-mentioned remote commander is one example. If it is the
one printed under a remote commander as “DVD”, any remote com-
mander can be operated.
COLD RESET
The cold reset clears data stored in microcomputer’s RAM to ini-
tial conditions.
Procedure:
1. Press three buttons of [ x ], [
Z
] and [
?/1
] on the set simultane-
ously.
2. “COLD RESET” appears on the
fl uorescent indicator tube. Af-
ter that, the
