    XL-DK257N 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.
  • Page 71 XL-DK257N (1) Focus-RF system check. Although a CD is inserted and the cover is closed, "NO DISC" is displayed. 1. Does the pickup move? Sled motor (M2A). 2. Does the focus (lens) move up and down ? Check the focus peripheral circuit.
  • Page 72 XL-DK257N (2) Tracking system check. Check the TE waveform at pin 6 on IC1. If the waveform shown in Figure 4 appears and soon after NO The tracking servo is not activated. DISC appears ? Check the peripheral circuits at pins 6, 7, 10, 98 and 100 on IC1, pins 17, 18, 35 and 36 on IC2 and FFC1.
  • Page 73 XL-DK257N (4) PLL system check. When a disc is loaded, start play operation. TMAX LPFO The RF waveform is normal, but the TOC data cannot be read. Check the TMAX waveform. (Figure 6) Figure 6 Check around Pins 72, 73, 74, 75, 76 and 78 on IC1.
