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

SECTION 1

SERVICING NOTE

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.

• In performing the repair with the power supplied to the set,
removing the MAIN board causes the set to be disabled.
In such a case, fix a convex part of the open/close detect switch
(S806 on MAIN board) with a tape in advance.
Handle the FLEXIBLE board (overwrite head) with care, as it
has been soldered directly to the MAIN board.
In repairing the component side of MAIN board, connect the
FLEXIBLE board (overwrite head) and the MAIN board with
the lead wires in advance. (See page 7)

• Replacement of CDX2671-204GA (IC801) used in this set
requires a special tool.

• On the set having the microcomputer version 1.000, some
adjusted values were set in the manual mode at the shipment,
but these data will be cleared when the NV is reset. Therefore,
on the set having the microcomputer version 1.000, change the
adjusted values following the Change of Adjusted Values
immediately after the NV was reset. (See page 17)

TEST MODE

MZ-R501/R501PC

4-1. Outline

• This set provides the Overall adjustment mode that allows CD
and MO discs to be automatically adjusted when in the test mode.
In this overall adjustment mode, the disc is discriminate between
CD and 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.

4-2. Setting Method of T est Mode

There are two different methods to set the test mode:
1 Short TAP801 (TEST) on the MAIN board with a solder bridge

(connect pin 3 of IC801 to the ground). Then, turn on the
power.

with the chassis, etc.
For test mode set with the method 2:
Turn off the power.
Note: If electrical adjustment (see page 17) has not been finished

completely, always start in the test mode. (The set cannot

3. During each test, the optical pick-up moves outward or in­ward while the > or . key is pressed for several sec­onds respectively.

4. Each test item is assigned with a 3-digit item number;
100th place is a major item, 10th place is a medium item, and
unit place is a minor item.
The values adjusted in the test mode are written to the
nonvolatile memory (for the items where adjustment was
made).

4-8. Self-Diagnosis Result Display Mode

This set uses the self-diagnostic function system in which if an
error occurred during the recording or playing, the mechanism
control block and the power supply control block in the
microcomputer detect it and record its cause as history in the
nonvolatile memory.
By checking this history in the test mode, you can analyze a fault
and determine its location.
Total recording time is recorded as a guideline of how long the
optical pickup has been used, and by comparing it with the total
recording time at the time when an error occurred in the self­diagnosis result display mode, you can determine when the error
occurred.
Clear both self-diagnosis history data and total recording time, if
the optical pickup was replaced.

• Self-Diagnosis Result Display Mode Setting Method

ELECTRICAL ADJUSTMENTS

MZ-R501/R501PC

5-1. Outline

• In this set, automatic adjustment of CD and MO can be per­formed by entering the test mode (see page 11).
However, before starting automatic adjustment, the memory
clear, power supply adjustment, and laser power check must be
performed in the manual mode.

• A key having no particular description in the text, indicates a
set key.

• For the LCD display, the LCD display on the set is shown.

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

• Digital voltmeter

• Laser power meter LPM-8001

(Part No. : J-2501-046-A)

• Thermometer (using the Temperature Correction)

3. Unless specified otherwise, supply DC 3V from the DC IN
3V jack (J601).

4. Switch position

Common note on Printed Wiring Board:

• Y : parts extracted from the conductor side.

• : Pattern from the side which enables seeing.

(The other layer’s patterns are not indicated.)

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.

Replacement of IC801 on main board

*

requires a special tool.

• Lead Layouts

Lead layout of conventional IC CSP (chip size package)

surface

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/
specified.

• % : indicates tolerance.

• 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.

• A : B+ Line.

• Total current is measured with Minidisc installed.

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

• Voltage and waveforms are dc with respect to ground
under no-signal conditions.
no mark : PB
( ) : REC

• 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.

E : PB
