CD-M8000W/CP-M8000 TROUBLESHOOTING 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-M8000W/CP-M8000 Stopped CH1=500 mV DC 10:1 (1) Focus-HF system check. Although a CD is inserted and the cover is closed, "NO DISC" is displayed. CH3=500 mV DC 10:1 T 500 ms/div (500 ms/div) NORM:20 kS/s FDO 1 Press the OPEN/CLOSE switch (SW1) without inserting a disc, and try starting the playback operation.

CD-M8000W/CP-M8000 (2) Tracking system check. Check the TE waveform at pin 15 on IC1. If the waveform shown in Figure 40-1 appears and soon after NO DISC appears ? Yes The tracking servo is not activated. Check the peripheral circuits at pins 14, 15 and 20 on IC1, and CNS1A/B. Yes A normal jump operation cannot be completed or the beginning of the track cannot be found. Check the around pin 20 on IC1. No "Initialization" is possible, but play is not possible ? No "Initialization" is not possible.
