CD-BA3000 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 micro-micro-farad and the unit of the capacitor without such a symbol is microfarad.

CD-BA3000 TROUBLE SHOOTING When the CD does not function When the CD section does not operate when the objective lens of the optical pickup is dirty, this section may not operate. 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-BA3000 (1) Focus-HF system check Stopped CH1=500mV DC 10:1 Although a CD is inserted and the cover is closed, "NO DISC" is displayed. Press the OPEN/CLOSE switch (SW1) without inserting a disc, and try starting the playback operation.

CD-BA3000 (2) Tracking system check Check the TE waveform at pin 18 on IC1. If the waveform shown in Figure 39-1 appears and soon after NO DISC appears. Yes The tracking servo is not activated. Check the peripheral circuits at pins 18 and 19 on IC1, pin 23 on IC2, and CNS1A/B. Yes A normal jump operation cannot be completed or the beginning of the track cannot be found. Check the around pin 23 on IC2. No "Initialization" is possible, but play is not possible. No "Initialization" is not possible.
CD-BA3000 (4) PLL system check Stopped CH1=500mV DC 10:1 CH3=1V DC 10:1 1999/04/05 17:33:17 CH4=1V 500ms/div (500ms/div) DC 10:1 NORM:20kS/s PDO1 When a disc is loaded, start play operation. 3 4 The HF waveform is normal, but the TOC data cannot be read.
