Mass (approx.) 3.8 kg

Design and specifications are subject to change
without notice.

Laser component in this product is capable of emitting radiation
exceeding the limit for Class 1.

This appliance is classified as
a CLASS 1 LASER product.
This marking is located on
the rear or bottom exterior.

CAUTION

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

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

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.

SAFETY-RELATED COMPONENT WARNING!!

COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINE
WITH MARK 0 ON 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.

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.

NOTES ON LASER DIODE EMISSION CHECK

The laser beam on this model is concentrated so as to be focused on
the disc reflective 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.

DISC TRA Y LOCK

The disc tray lock function for the antitheft of an demonstration
disc in the store is equipped.

Setting Procedure :

1. Press the ?/1 button to turn the set on.

2. Press the [FUNCTION] button to set DVD function.

3. Insert a disc.

4. Press the

x button and the A button simultaneously for five

seconds.

5. The message “LOCKED” is displayed and the tray is locked.

Releasing Procedure :

1. Press the x button and the A button simultaneously for fiv e
seconds again.

2. The message “UNLOCKED” is displayed and the tray is
unlocked.

Note: When “LOCKED” is displayed, the tray lock is not released by

turning power on/off with the ?/1 button.

Note on MAIN board replacement

New part of EEP ROM (IC1103) on the MAIN board cannot be used.
Therefore, if the mounted MAIN board (A-1191-800-A, etc.) is replaced,

exchange new EEP ROM (IC1103) with that used before the replacement.

Self-diagnosis Function

(When letters/numbers appear in the
display)

When the self-diagnosis function is activated to
prevent the system from malfunctioning, a 5­character service number (e.g., C 13 50) with a
combination of a letter and 4 digits appears on
the screen and the front panel display. In this
case, check the following table.

C:13:50

First 3
characters of
the service
number

C 13 The disc is dirty.

C 31 The disc is not inserted correctly.

E XX
(xx is a number)

When displaying the version
number on the screen

When you turn on the system, the version
number [VER.X.XX] (X is a number) may
appear on the screen. Although this is not a
malfunction and for Sony service use only,
normal system operation will not be possible.
Turn off the system, and then turn on the system
again to operate.

Cause and/or corrective action

,Clean the disc with a soft cloth

,Restart the system, then re-insert

the disc correctly.

To prevent a malfunction, the
system has performed the self­diagnosis function.

,Contact your nearest Sony

dealer or local authorized Sony
service facility and give the 5­character service number.

Example: E 61 10

PRECAUTION WHEN INSTALLING A NEW OP UNIT /
PRECAUTION BEFORE UNSOLDERING THE STATIC ELECTRICITY
PREVENTION SOLDER BRIDGE

When installing a new OP unit, be sure to connect the flexible printed circuit board first of all before removing the static
electricity prevention solder bridge by unsoldering. Remove the static electricity prevention solder bridge by unsoldering
after the flexible printed circuit board has already been connected.
(Do not remove nor unsolder the solder bridge as long as the OP unit is kept standalone.)
