Why is there no sound from my JBL Speakers?

If your JBL speaker powers on but produces no sound and the SIGNAL LED does not light up, the issue likely lies with the signal source or the connections. First, check the VU meters on the source mixer to ensure it is sending a signal. Verify that the tape or CD is playing, or use headphones to confirm that the instrument is actually sending an audio signal. Also, disconnect and re-seat the signal cables to ensure they are properly connected. If the problem persists, replace the cable with a known-good cable to rule out any faulty cables.
