Rca 5 disc changer RS 2640 I have everything lighting up and functioning but I have no sound.?

If your RCA 5-disc changer RS 2640 is lighting up and functioning but not producing sound, check the audio connections to ensure they are secure and correctly plugged into your amplifier or receiver. Verify that the correct input source is selected on your audio system. Additionally, inspect the volume settings on both the changer and the connected device, as they may be muted or set too low. If all else fails, consider testing with different cables or speakers to rule out any hardware issues.
