CD-ES700/CD-ES77 Service E Market CD-ES700/CD-ES77 Manual 7. FLOWCHART CHAPTER [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-ES700/CD-ES77 (1) Focus-HF system check. Stopped CH1=500 mV DC 10:1 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. TDO 3 CH1 v/DIV 500 mV =Filter= Smoothing : ON BW : FULL =Offset= CH1 : 0.000 V CH2 : 0.0 V CH3 : 0.000 V CH4 : 0.
PAGE 72
CD-ES700/CD-ES77 (2) Focus-HF system check. Check the TE waveform at pin 17 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 The tracking servo is not activated. Check the peripheral circuits at pins 16, 17 and 22 on IC1, and FFC1. Yes A normal jump operation cannot be completed or the beginning of the track cannot be found. Check the around pin 22 on IC1. No "Initialization" is not possible.
