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 WHOSE PART NUMBERS APPEAR AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTS PUBLISHED BY SONY.

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.

RELEASING THE DISC TRAY LOCK

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

number labels marked directly on the back panel, the model number labels have no relative part numbers.

Because of this, determine the model through the marked model

number when comparing the difference between these models.

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

HCD-EX66/EX88/EX99

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.)

Note:

1. CD Block is basically constructed to operate without adjustment.

2. Use YEDS-18 disc (Part No. 3-702-101-01) unless otherwise indicated.

3. Use an oscilloscope with more than 10 MΩ impedance.

4. Clean the object lens by an applicator with neutral detergent when the signal level is low than speciﬁ ed value with the following checks.

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: (SIDE B) Parts face side: (SIDE A)

• Abbreviation AR : Argentina model E2 : 120V AC area in E model E4 : 220 – 240V AC area in E model E51 : Chilean and Peruvian models EA : Saudi Arabia model MX : Mexican model

Parts on the pattern face side seen from the pattern face are indicated. Parts on the parts face side seen from the parts face are indicated.

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.

– BD76 Board –

no mark : CD PLAY

– Other Boards –

no mark : TUNER (FM/AM)

* : Impossible to measure

• 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.

Voltage variations may be noted due to normal production

tolerances.

• Circled numbers refer to waveforms.

• Signal path.
