My panasonic system 5 cd changer sa ak 133 turning fm , but AM not turning even single station?

It sounds like your SA AK 133 5 CD changer has some issues. The AM radio band not turning on could be due to a faulty antenna, a problem with the power supply, or a software issue. To resolve this issue, you should check the antenna first and make sure it is connected properly. If the antenna is connected properly and the issue persists, you may need to check the power supply or contact the manufacturer for assistance. The issue with the CD not ejecting could be due to a faulty drive motor or a faulty eject mechanism. To resolve this issue, you should check the drive motor and the eject mechanism and replace them if needed. The issue with the tapes not working could be due to a faulty cassette player mechanism. To resolve this issue, you should replace the cassette player mechanism.
