• Be careful not to apply force on the conductor when soldering
or unsoldering.

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.

CAUTION

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

SECTION 1

SERVICING NOTE

• When repairing this device with the power on, if you remove
the MAIN board or open the upper panel assy , this device stops
working.
In this case, you can work without the device stopping by fas­tening the hook of the open/close detect switch (S801) with tape.

S801

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

Never look into the laser diode emission from right avove when
checking it for adustment. It is feared that you will lose your sight.

NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK
(LCX-2R)

The laser diode in the optical pick-up block may suffer electrostatic
break-down easily. When handling it, perform soldering bridge to
the laser-tap on the flexible board. Also perform measures against
electrostatic break-down sufficiently before the operation. The
flexible board is easily damaged and should be handled with care.

• This set is designed to perform automatic adjustment for each
adjustment and write its value to EEPROM. Therefore, when
EEPROM (IC802) has been replaced in service, be sure to per­form automatic adjustment and write resultant values to the new
EEPROM.
(Refer to page 20.)

• Replacement of CXD2660R (IC502) and CXR701081 (IC801)
used in this set requires a special tool. Therefore, they cannot be
replaced.

TEST MODE

4-1. OUTLINE

• This set provides the Overall adjustment mode (Assy mode) that
allows CD and MO disc to be automatically adjusted when in
the test mode. In this overall adjustment mode, the protect switch
is detected to judge the disc, CD or MO, and each adjustment is
automatically executed in order. If a fault is found, the system
displays its location. Also, the manual mode allows each indi­vidual adjustment to be automatically adjusted.

• The keys in the description refer to the keys on both set and
remote commander unless otherwise specified. Though LCD
display shows the LCD of the remote commander, same con­tents are also displayed on the LCD of the set.

4-2. TEST MODE

4-2-1. Setting Method of Test Mode

There are two different methods to set the test mode:
1 Short BP801 (TEST) on the MAIN board with a solder bridge

(connect pin y; of IC801 to the ground). Then, turn on the
power.

– MAIN BOARD (SIDE B) –

2 In the normal mode, turn on the HOLD switch on the set. While

pressing the

x key on the set, press the following remote

control keys in the following order:

> t > t . t . t > t . t

> t . t X t X

4-2-2. Operation in Setting the Test Mode

• When the test mode becomes active, first the display check mode
is selected. (Press

x key once, when the display check mode

is not active.)

• Other mode can be selected from the display check mode.

• When the test mode is set, the LCD repeats the following dis-

play.

4-6. SELF-DIAGNOSIS DISPLAY MODE

• This set uses the self-diagnosis system in which if an error oc-

curs in recording/playback mode, the error is detected by the
model control and power control blocks of the microprocessor
and information on the cause is stored as history in EEPROM.
By viewing this history in test mode, it helps you to analyze a
fault and determine its location.
Total recording time has been recorded as optical pick-up using
time, and it is compared with the total recording time in the
self-diagnosis display mode to find when an error occurred.
Clear both total recording time and the time in self-diagnosis
display mode, when the optical pick-up was replaced.

ELECTRICAL ADJUSTMENTS

5-1. OUTLINE

• In this set, automatic adjustment of CD and MO can be per­formed by entering the test mode. (See page 13)
However, before starting automatic adjustment, the memory
clear, power adjustment and temperature adjustment must be
performed in the manual mode.

• The keys in the description refer to the keys on both set and
remote commander unless otherwise specified.
Though LCD display shows the LCD of the remote commander,
same contents are also displayed on the LCD of the set.

5-2. PRECAUTIONS FOR ADJUSTMENT

1. Adjustment must be done in the test mode only.

After adjusting, release the test mode.

2. Use the following tools and measuring instruments.

• Test CD disc TDYS-1
(Part No. : 4-963-646-01)

• SONY MO disc available on the market

• Laser power meter LPM-8001
(Part No. : J-2501-046-A)

• Digital voltmeter

3. Unless specified otherwise, supply DC 3V from the DC IN 3V
jack.

4. Switch position

Common note on Schematic Diagram:

• All capacitors are in µF unless otherwise noted. pF: µµF
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

specified.

• % : indicates tolerance.

f

•

: internal component.

• C : panel designation.

Note:

The components identi­fied by mark 0 or dotted
line with mark 0 are criti­cal for safety .
Replace only with part
number specified.

Note:

Les composants identifiés par
une marque 0 sont critiques
pour la sécurité.
Ne les remplacer que par une
piéce portant le numéro
spécifié.

• A : B+ Line.

• Power voltage is dc 3V and fed with regulated dc power
supply from external power voltage jack.

• Voltages and waveforms are dc with respect to ground in
playback mode.
no mark : REC
( ) : PB

: Impossible to measure

∗

• Voltages are taken with a 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.
J : CD

Common note on Printed Wiring Boards:

• Y : parts extracted from the conductor side.

f

•

: internal component.

• : Pattern from the side which enables seeing.

Caution:
Pattern face side: Parts on the pattern face side seen from the
(Side B) pattern face are indicated.
Parts face side: Parts on the parts face side seen from the
(Side A) parts face are indicated.

• Main board is four-layer printed board.
However, the patterns of layers 2 and 3 have not been in­cluded in this diagrams.
