CD-MPX870W CHAPTER 6. CIRCUIT SCHEMATICS AND PARTS LAYOUT [1] Notes on schematic diagram • Resistor: To differentiate the units of resistors, such symbol as K and M are used: the symbol K means 1000 ohm and the symbol M means 1000 kohm and the resistor without any symbol is ohm-type resistor. Besides, the one with “Fusible” is a fuse type. • Capacitor: To indicate the unit of capacitor, a symbol P is used: this symbol P means pico-farad and the unit of the capacitor without such a symbol is microfarad.

CD-MPX870W CHAPTER 7. FLOWCHART [1] Troubleshooting 1. When the CD does not function The CD section may not operate when the objective lens of the optical pickup is dirty. Clean the objective lens, and check the playback operation. When this section does not operate even after the above step is taken, check the following items. Remove the cabinet and follow the trouble shooting instructions.
CD-MPX870W Stopped CH1=500 mV DC 10:1 (1) Focus-HF system check. CH3=500 mV DC 10:1 T Although a CD is inserted and the cover is closed, "NO DISC" is displayed. 500 ms/div (500 ms/div) NORM:20 kS/s FDO 1 Press the Tray1 CD Eject Button without inserting a disc, and try starting the playback operation.

CD-MPX870W (2) Tracking system check. Check the TE waveform at pin 16 on IC1. If the waveform shown in Figure 4 appears and soon after NO DISC appears ? No "Initialization" is possible, but play is not possible ? Yes Yes The tracking servo is not activated. Check the peripheral circuits at pins 15, 16 and 23 on IC1, and FFC1. A normal jump operation cannot be completed or the beginning of the track cannot be found. Check the around pin 23 on IC1. No "Initialization" is not possible.
