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.

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 possible, but play is not possible ? No "Initialization" is not possible.
