Why is there no music coming from my Karaoke USA GQ450 Karaoke System?

  If your Karaoke USA Karaoke System is producing no music, first, ensure the AUX IN cable is correctly connected to the appropriate AUX IN input jack on the front. If that's not the issue, check if the unit is set to BLUETOOTH mode and switch the Function switch to AUX IN mode. Also, verify that the volume isn't too low on both your smart device and the unit itself; increase the volume on both.

  Barbara FisherAug 17, 2025
  If your Karaoke USA Karaoke System displays no picture, make sure that a disc is inserted. If a disc is already inserted, ensure that the disc isn't stained, warped, or scratched, and that it is in good condition. Check that you are using the correct disc type; the unit plays CD, CD+G, and MP3+G formats. Also, ensure the Function switch is in DISC mode.
