It sure dosent sound good!! The clicking sound you here are the protection relays to assist in protecting your speakers from blowing out. Your output devices are shorted it sounds like. Do not ever ever attemp to jump out those relays as it will burn out your speakers and possibly burn down your house!. Theres alot of current inthese amps for high power so if your not a tech and you think its worth it take the unit in to be looked at as there are no serviceable user parts inside these units . Sorry to have to tell ya this.. Good Luck
The amp protection circuit has been activated. Remove the power cord from the wall outlet immediately. Disconnect all speaker cables and input sources, and leave the AV receiver with its power cord disconnected for 1 hour. After that, reconnect the power cord and reconnect an input and a pair of speaker wires onto the unit. If the receiver still does not turn on than you will have to bring it in for service. Turn up the volume and if the receiver doesn't shut down, power off the receiver and add another pair of speakers. Power up the unit again and turn up the volume. If it doesn't shut down, power off the unit again. Now connect all your input sources and turn on your receiver. If the unit shuts down again, your unit will need to be further serviced at an authorized Onkyo service center.
