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 270C 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.

SECTION 1 SERVICING NOTE

1-1. SERVICE MODE
Mode to allow the mechanical parts to operate with the main board open. This set uses the photo reflector PH701 to detect the rotation of the idler gear. PH701 is on the main board and so removal of the main board does not allow the set to detect the rotation of the idler gear. This makes motor control impossible which prevents normal operation. When repairing the set as energized with the main board removed, proceed as follows: 1. Setting 1) Remove the cabinet (rear) (refer to the Disassembly) and open the main board. 2) Apply a trapezoidal of 10 to 100 Hz (at 1.3 V) from oscillator to TP20. (Connect the ground to TP30.) 3) Supply DC 3.0 V to the positive and negative terminals of the battery with a stabilized power supply. 2. FF mode 1) Apply a trapezoidal to hall sensor TP20. 2) Press the FF key. 3) Turn on the S103 (POWER) switch. 3. REW mode 1) Apply a trapezoidal to hall sensor TP20. 2) Press the REW key. 3) Turn on the S103 (POWER) switch. 4. PLAY mode 1) Apply a trapezoidal to hall sensor TP20. 2) Press the PLAY key. 3) Change over the S101 (REC/PB) switch to PB side. 4) Turn on the S103 (POWER) switch. 5. REC mode 1) Apply a trapezoidal to hall sensor TP20. 2) Press the REC key. 3) Change over the S101 (REC/PB) switch to REC side. 4) Turn on the S103 (POWER) switch.

PRECAUTION

1. Clean the following parts with a denatured-alcohol-moistened swab : record/playback/erase head pinch roller capstan rubber belt 2. Demagnetize the record/playback/erase head with a head demagnetizer. (Do not bring the head demagnetizer close to the erase head.) 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 (1.3 V) unless otherwise noted.

SECTION 8 ELECTRICAL PARTS LIST
NOTE: Due to standardization, replacements in the parts list may be different from the parts specified 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 ordering these items. SEMICONDUCTORS In each case, u : , for example: uA. : A. uPA. : PA. uPB. : PB. uPC. : PC. uPD. : PD. CAPACITORS uF : F COILS uH : H
