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.

CAUTION

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

This appliance is classified as
a CLASS 1 LASER product.
The CLASS 1 LASER
PRODUCT 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 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.

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.

pressed, the display changes starting from MC version, GC
version, CD version, CDD version, CDMA version, CDMB
version, BDA version, BDB version, ST version, TA version,
TM version, and TC version this order , and returns to the MC
version display on the liquid crystal display.

6. Press the [REPEAT/FM MODE] key, the key check mode is
activated.

7. In the key check mode, the liquid crystal display displays “K0”.
Each time a key is pressed, “K” value increases. However,
once a key is pressed, it is no longer taken into account.

8. When [FUNCTION] key is pressed while the version numbers
are being displayed except model and destination, year, month
and day of the software creation display. When [FUNCTION]
key is pressed again, the display returns to the software version
display. When [PLAY MODE/DIRECTION/TUNING MODE] key
is pressed while year, month and day of the software creation
are being displayed, the year, month and day of creation of
the software versions are displayed on the liquid crystal display
in the same order of version display.

9. To release this mode, press three keys in the same manner as
step 2, or disconnect the power cord.

[COLD RESET]

• The cold reset clears all data including preset data stored in
the RAM to initial conditions. Execute this mode when
returning the set to the customer.

Procedure:

1. Press the I/1 key to turn the power ON.

2. Press three keys of I/1 , [DISPLAY] and x (TAPE)

simultaneously.

3. The liquid crystal display becomes blank instantaneously, and
the set is reset.

[SHIP MODE (NO MEMORY CLEAR)]

• This mode moves the optical pick-up to the position durable
to vibration. Use this mode when returning the set to the
customer after repair.

Procedure:

1. Press the I/1 key to turn the power ON.

2. Press the [FUNCTION] key to select “CD”.

3. Press three keys of [DSGX], x (CD) and +simulta­neously and the ship mode is set.

[SHIP MODE (MEMORY CLEAR)]

• This mode moves the optical pick-up to the position durable
to vibration. Use this mode when returning the set to the
customer after repair.

Procedure:

1. Press the I/1 key to turn the power ON.

2. Press the [FUNCTION] key to select “CD”.

3. Press three keys of [DSGX], x (CD) and – simulta­neously.

4. After the “ST ANDBY” display blinks, “LOCK” is displayed
on the liquid crystal display, and the ship mode is set.

[CD SLOT LOCK MODE]

• This mode is used to unable to take sample disc out of disc
slot in the shop.

Procedure:

1. Press the I/1 key to turn the power ON.

2. Press the [FUNCTION] key to select “CD”.

3. While pressing the Z (CD) key, press the x (CD) key for
5 seconds.

4. The message “LOCKED” is displayed on the liquid crystal
display and the disc slot is locked. (Even if pressing
the Z (CD) key, the message “LOCKED” is displayed on
the liquid crystal display and the disc slot is locked)

5. To release from this mode, pressing the Z (CD) key, press
the x (CD) key for 5 seconds.

6. The message “UNLOCKED” is displayed on the liquid crystal
display and the disc slot is unlocked.

[CD SERVICE MODE]

• This mode can run the CD sled motor freely. Use this mode,
for instance, when cleaning the optical pick-up.

Procedure:

1. Press the I/1 key to turn the power ON.

2. Press the [FUNCTION] key to select “CD”.

3. Press three keys of [PLAY MODE/DIRECTION/TUNING MODE],
M L and x (CD) simultaneously.

4. Press the M L key to move the optical pick-up to outside

track, or press the l m key to inside track.

5. Press the CD u key, “LD OFF” is displayed and laser diode

is turned off. Each time CD u key is pressed, laser diode
ON/OFF seitch is performed.

6. To release this mode, press the I/1 key.

[CD ERROR CODE MODE]

• This mode can be used for error display of CD section.

Procedure:

1. Press the I/1 key to turn the power ON.

2. Press the [FUNCTION] key to select “CD”.

2. Press the [FUNCTION] button to select CD function.

3. Press the I/1 button again to turn the power off (standby).

4. While pressing the x (CD) button, press the I/1 button.

5. It turns power on and display “CD POWER”, then display

“ON” or “OFF”.

[CHANGE-OVER THE AM TUNING INTERVAL]

(Singapore and Korean models)

The AM tuning interval can be changed over 9 kHz or 10 kHz.

Procedure:

1. Press the I/1 button to turn the power on.

2. Press the [TUNER, BAND] button to select TUNER (AM)

function.

3. Press the I/1 button again to turn the power off (standby).

4. While pressing the [TUNING +] button, press the I/1 button.

5. It turns power on and display “STEP 9kHz” or “STEP 10kHz”,

and thus the tuning interval is changed over.

PRECAUTION

1. Clean the following parts with a denatured alcohol-moistened
swab:

record/playback heads pinch rollers
erase head rubber belts
capstan idlers

2. Demagnetize the record/playback head with a head de-

magnetizer.

3. Do not use a magnetized screwdriver for the adjustments.

4. After the adjustments, apply suitable locking compound to

the parts adjusted.

5. The adjustments should be performed with the rated power

supply voltage unless otherwise noted.

Note:

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

2. Use YEDS-18 disc (3-702-101-01) unless otherwise indicated.

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

4. Clean the object lens by an applicator with neutral deter gent when the
signal level is low than specified value with the following checks.

5. Check the focus bias check when optical pick-up block is replaced.

Procedure :

1. Connect oscilloscope to TP (RFACI) and TP (VC) on the BD
board.

2. Press the I/1 button to turn the power ON, and press
the Z (CD) button to open the CD disc tray.

3. Set disc (YEDS-18) on the tray and press the CD u button
to playback.

4. Confirm that oscilloscope waveform is as sho wn in the figure
below. (eye pattern)
A good eye pattern means that the diamond shape (◊) in the
