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 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.
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.

WM-EX910 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 malfunction. Further, the DIRECTION switch (S702) is also mounted on the MAIN board, and with the board removed, the mechanism position 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 follow. 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 DIRECTION 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 towards the side REV and then to the side FWD. Move the DIRECTION 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) according 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.
