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.

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.

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

MZ-B100

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 above when
checking it for adjustment. It is feared that you will lose your sight.

NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK
(LCX-4R)

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.

• 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 (S804).

S804

• 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 Section 5 Electrical Adjustment. (page 19))

• Replacement of CXD 2671-209GA (IC801) used in this set re­quires a special tool.

OPTICAL PICK-UP FLEXIBLE BOARD

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 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.

SECTION 4

TEST MODE

[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.

[Setting Method of Test Mode]

There are two different methods to set the test mode:
1 Short SL801 (TEST) on the MAIN board with a solder bridge

(connect pin 202 of IC801 to the ground). Then, turn on the
power.

• 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.

[Releasing the Test Mode]

For test mode set with the method 1:
Turn off the power and open the solder bridge on SL801 (TEST)
on the MAIN board.

Note: Remove the solders completely. Remaining could be shorted with

the chassis, etc.

For test mode set with the method 2:
Turn off the power.

Note: If electrical adjustment (see page 19) has not been finished com-

pletely, always start in the test mode. (The set cannot start in nor­mal mode.)

[Self-Diagnosis Display Mode]

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

1. Setting the test mode. (See page 12)

[Clearing Self-Diagnosis Data and Total Recording Time]

1. Setting the test mode. (See page 12.)

2. Move up the jog key on the set or press the [DISPLAY] key on the remote commander activates the self-diagnosis display mode.

3. Press the X key or [REC] key on the set during display of self-diagnosis data when clearing the self-diagnosis data, or during display of

total recording time when clearing the total recording time. Thus, “ClrOK?” will be displayed on the LCD, and press the same key again,
and when self-diagnosis data is cleared “ErrCLR” is displayed and the data is cleared. Also when total recording time is cleared, “ ReeT
O” is displayed and it is cleared.

[Key Check Mode]

This set can check if the set and remote commander function nor­mally.

• Setting Method of Key Check Mode

1. Setting the test mode. (See page 12)

2. Press the [T MARK] activates the key check mode where all

segments of LCD turn OFF. (At the last two digits of DOT
section, AD value of remote commander key line is displayed
in hexadecimal)

3. When each key is pressed, it is displayed on the LCD, imply-

ing that it was successfully checked as shown below. How­ever, for the slide switch on the set, it is not checked unless it
is reciprocated.

* The key pressed to enter the key check mode was already

checked at that time.

ELECTRICAL ADJUSTMENTS

MZ-B100

[Outline]

• In this set, automatic adjustment of CD and MO can be per­formed by entering the test mode. (See page 12)
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.

[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)

Available SONY CD disc

• Recorded MO disc PTDM-1
(Part No. : J-2501-054-A)

Available SONY MO disc (recorded)

• 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
