      If there is no sound coming from your JBL speakers, first ensure that your receiver is powered on and playing audio. Then, verify the 'Balance' control on your receiver is properly adjusted. Check all the wires and connections between the receiver/amplifier and the speakers to make sure they are connected correctly. Also, inspect the speaker wires to ensure that none are frayed, cut, or punctured. If you are using multiple pairs of speakers, confirm that the minimum impedance requirements of your receiver/amplifier are met.
