How to fix a Harman Kardon Receiver that won't turn on?
If your Harman Kardon Receiver is not functioning when you turn on the main power switch, ensure that the power cord is properly plugged into a working power outlet. Check if the outlet is controlled by a switch.
What to do if my Harman Kardon Receiver can't connect to the network?
If you're unable to establish a network connection with your Harman Kardon Receiver, the network programming may require rebooting. Cycle the receiver into standby mode and then turn it back on.
What to do if my Harman Kardon AVR 2700 Receiver shows 'PROTECT' and has no sound?
If you're not getting any sound and the display shows 'PROTECT', it means the amplifier has gone into protection mode. This could be due to a short circuit in your speaker wires. Check all speaker wires at both the speaker and receiver connections for any crossed wires. If the issue persists, it may be due to internal problems, and you should contact your local Harman Kardon service center.
Why is my Harman Kardon AVR 2700 Receiver not responding to the remote control?
If your Harman Kardon Receiver isn't responding to the remote, the batteries might be weak. Try changing the batteries in the remote. Also, make sure that the remote sensor on the front panel of the receiver isn't blocked and is in direct line of sight with the remote.
What to do if my Harman Kardon AVR 2700 Receiver has display but no sound or picture?
If the front-panel message display lights up but you're not getting any sound or picture from your Harman Kardon Receiver, ensure that all input and speaker connections are securely connected. Also, make sure the mute button is not activated, and the volume is turned up.
Why is my Harman Kardon AVR 2700 tuner buzzing?
If you're experiencing intermittent buzzing in the tuner of your Harman Kardon Receiver, it might be due to local interference. Try moving the receiver or antenna away from computers, fluorescent lights, motors, or other electrical appliances.
Why is there no sound from the surround speakers on my Harman Kardon AVR 2700 Receiver?
If you're not getting sound from the center or surround speakers on your Harman Kardon Receiver, first check that you've selected a surround mode other than stereo. If the program material is monophonic, it won't have surround information. Also, verify the speaker configuration in the setup menu. The surround decoder may not create center or surround-channel information from nonencoded stereo programs.
Why do the remote buttons light up, but my Harman Kardon AVR 2700 doesn't respond?
If the remote buttons light up, but your Harman Kardon Receiver isn't responding, the remote might be in Zone 2 mode. Slide the zone selector switch to the Zone 1 position.
Why can't I access surround-back speaker settings on my Harman Kardon AVR 3700?
If you cannot access the surround-back speaker settings and the test tone doesn't play through those speakers on your AVR 3700/AVR 370 Harman Kardon Receiver, it could be because multi-zone operation has been selected, and amplifier channels have been assigned to Zone 2. Use the speaker setup menu to reassign the assigned amp to the surround back left and right channels.
