Why my Harman JBL Professional Eon 610 Speakers have no sound when turned on?

If your Harman speaker comes on but produces no sound, the problem might be with the signal source or the cables. First, check the VU meters on the source mixer and verify that the tape or CD is playing. Use headphones to confirm the instrument is sending an audio signal. Also, disconnect and re-seat the signal cables, and replace any suspected faulty cables with known-good ones.
