What to do if Harman Kardon AVR 151 front-panel display lights, but there’s no sound or picture?
If you're not getting any sound or picture from your Harman Kardon Receiver, even though the front panel lights up, make sure all the input and speaker connections are secure. Also, check if the Mute button is activated and ensure the volume isn't turned all the way down.
Why is there no sound from any speaker on my Harman Kardon AVR 151?
If you are not getting any sound from your Harman Kardon Receiver speakers, it might be in protection mode because of a possible short circuit. Check all the speaker wires at both the speaker and AVR connections to make sure there are no crossed wires. If this doesn't work, the unit might have internal problems and you should contact your local Harman Kardon service center.
