The continuous play button is on the remote control.

In most cases when the CD does not play it is possible that the optical head is a suspect. Sometimes it might pick up ordinary audio CD but will not play other formats. This indicates that the optical head is weak and so there is no detection or scanning of the CD . If the optical is working the tracks will be read immediately but with no scanning the laser head can be defective.
Sometimes certain cleaner disks will not be tracked to run for cleaning as it will not be read and so will reject. Hence it is ideal to manually clean the laser head eye using a cleaning swap /cotton bud with gentle pressure on the lens eye.
If there is no result then watch if the CD spins or tries to spin. If so the board seems to work unless a test is taken on the main board but the possibility of a defective optical head can be the suspected fault.
If any of the above seems otherwise we must recheck with possibilities of a malfunction of the main processor board

It does have an aux input with two levels but this isn't suitable for a turntable. A suitable input should have RIAA correction with a sensitivity of just a few millivolts for a magnetic cartridge.

The sound you're hearing could be due to a variety of reasons, such as a loose connection, a malfunctioning component, or a power issue. Here are some steps you can take to troubleshoot the issue: Check the speaker connections: Ensure that the speaker wires are properly connected to the receiver and the speakers. Make sure that the positive and negative terminals are correctly aligned. You can also try disconnecting and reconnecting the wires to ensure a secure connection. Check the power source: Ensure that the receiver is plugged into a working power outlet and that the power cord is securely connected to the receiver. You can also try plugging the receiver into a different power outlet to see if that resolves the issue. Check the volume level: Ensure that the volume level on the receiver is not set too high. High volume levels can cause distortion and other issues. Reset the receiver: Try resetting the receiver to its default settings. To do this, turn off the receiver and unplug it from the power source. Wait for a few minutes, then plug the receiver back in and turn it on. If these suggestion don't help, you may have to seek professional repair.
