CD-M4000W/CP-M4000 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..

Although a CD is inserted and the cover is closed, “NO DISC” is displayed. r- Press the OPEN/CLOSE switch (SWl) without inserting a disc, and try starting the playback operation. Figure 42-1 c I 1. Does the pickup move to the PICKUP-IN Switch (SW4) oosition ? No Sled motor (MZ). I- 2. Does the focus (lens) move up and down ? (Waveform drawing Figure 42-l) t-4 No Check the focus peripheral circuit. I No 3. Is the laser lit ? No 4.
