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 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.

CAUTION

Use of controls or adjustments or performance of procedures
other than those specifi ed herein may result in hazardous radia-
tion exposure.

This appliance is classifi ed as
a CLASS 1 LASER product.
This marking is located on the
rear exterior.

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

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 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 refl 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.

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 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.

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

HCD-EX600/EX700/EX900

When installing a new OP unit, be sure to connect the fl exible
printed circuit board fi rst of all before removing the static electric-
ity prevention solder bridge by unsoldering.
Remove the static electricity prevention solder bridge by unsolder­ing after the fl exible printed circuit board has already been con-
nected.
(Do not remove nor unsolder the solder bridge as long as the OP
unit is kept standalone.)

THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is printed in each block.)

For Printed Wiring Boards.

Note:

• X : Parts extracted from the component 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 the pattern face are indicated.
Parts on the parts face side seen from

For Schematic Diagrams.

Note:

• All capacitors are in μF unless otherwise noted. (p: pF) 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
specifi ed.

• f : Internal component.

• 2 : Nonfl ammable resistor.

• C : Panel designation.

Note: The components identifi ed by mark 0 or dotted

line with mark 0 are critical for safety.

Replace only with part number specifi ed.

• A : B+ Line.

• B : B– Line.

• Voltages and waveforms are dc with respect to ground
under no-signal (detuned) conditions.

• Voltages are taken with VOM (Input impedance 10 MΩ).

Voltage variations may be noted due to normal production

tolerances.

• Waveforms are taken with a oscilloscope.
