Notes on chip component replacement
• Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be dam-
aged by heat.
Flexible Circuit Board Repairing
• Keep the temperature of the soldering iron around 270 ˚C dur-
ing 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.
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  PUB-
LISHED  BY  SONY.

SECTION  1
SERVICING  NOTES
This set detects the rotation of the idler gear (A) (side S and side
T) using the photo reflector (PH701, 702). The PH701, 702 are
mounted on the MAIN board, therefore the idler gear (A) (side S
and side T) cannot be detected with the MAIN board removed. As
a result, the motor (M601) cannot be controlled, causing malfunc-
tion.
Further, the DIRECTION switch (S702) is also mounted on the
MAIN board, and with the board removed, the mechanism posi-
tion cannot be detected and the operation is not changed over.
Therefor, when the voltage check is executed with the MAIN board
removed, follow the procedure provided below.
1.
Setting
1) Refer to “3. DISASSEMBLY”, and remove the MAIN board.
2) Connect the MAIN board to the motor (M601) and the plunger
(PM701) using jumper wires. These can be connected easily
with the use of the extension tool (Part No. 1-769-143-11) (ten
in one set).
3) Short the lands by solder.
4) Connect the AF oscillator to the TP31 (PH-S), TP32 (PH-T)
and the TP (GND).
5) Supply 1.3 V to the battery terminals using the regulated power
supply.
2.
Preset state
To set the PLAY, FF, REW modes, the preset state must be set.
1) Check that the slider (NR) and the DIRECTION switch (S702)
are set to the center position. If not, set the preset state as fol-
low.
2) Move the DIRECTION switch (S702) to the side, which the
slider (NR) is facing.
3) The slider (NR) will move when the regulated power supply
switch is set to OFF once and then set to ON. Move the DI-
RECTION switch (S702) according to this timing and set to
the center position.
3.
FF, REW modes
1) Check that the preset state is set.
2) Input the square wave or sine wave to the TP31 (PH-S), TP32
(PH-T) and the TP (GND).
3) Move the jog lever (S703) toward [FF] or [REW].
4.
PLAY mode
1) Check that the preset state is set.
2) Input the square wave or sine wave to the TP31 (PH-S), TP32
(PH-T) and the TP (GND).
3) Press the jog lever (S703) will move the slider (NR) once to-
wards the side REV and then to the side FWD. Move the DI-
RECTION switch (S702) according to this timing will set the
PLAY mode (side FWD). Press the jog lever (S703) another time
for a second and move the DIRECTION switch (S702) ac-
cording to the movement of the slider (NR) will set the PLAY
mode (side REV).
Note 1: If the above fails, perform from preset again.
Note 2: When using headphones, the timing for move the DIRECTION
switch (S702) can be determined from the beep sound.

NOTE:
• Due to standardization, replacements in the
parts list may be different from the parts speci-
fied in the diagrams or the components used
on the set.
• -XX and -X mean standardized parts, so they
may have some difference from the original
one.
• RESISTORS
All resistors are in ohms.
METAL: Metal-film resistor.
METAL OXIDE: Metal oxide-film resistor.
F: nonflammable
• Items marked “*” are not stocked since they
are seldom required for routine service.
Some delay should be anticipated when order-
ing these items.
• SEMICONDUCTORS
In each case, u: µ, for example:
uA. .
: µA. .
uPA. . : µPA. .
uPB. . : µPB. .
uPC. . : µPC. .
uPD. . : µPD. .
• CAPACITORS
uF: µF
• COILS
uH: µH
The components identified by
mark 0 or dotted line with mark
0 are critical for safety.
Replace only with part number
specified.
When indicating parts by reference
number, please include the board.
