CD-E500 CD-E55/E44 TROUBLESHOOTING 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. "Track skipping and/or no TOC (Table Of Contents) may be caused by build up of dust other foreign matter on the laser pickup lens.

CD-E500 CD-E55/E44 (2) Tracking system check. Check the TE waveform at pin 15 on IC401. If the waveform shown in Figure 42-1 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 IC401, and FC401. Yes A normal jump operation cannot be completed or the beginning of the track cannot be found. Check the around pin 20 on IC401. No "Initialization" is possible, but play is not possible ? No Data cannot be read.
