Questions and answers
The CD player is not recognizing the discs that iare inserted
The Aiwa Z-L720 CD player may not be recognizing discs due to issues with the optical block (PICK-UP Assy PWB, KSS-213F). The service manual warns that electrostatic potential on the body or clothes can damage the laser diode in the optical block. If the laser diode is damaged or misaligned, the CD player may fail to read discs. Additionally, there could be issues with the CD mechanism (6ZG-1), which requires checking in the relevant service manual. Removing protective solder after replacing the optical block is also necessary for proper operation.
