Re: onkyo reciever keeps shutting off

Unplug all your speakers from the back. If it still goes into protect mode when you try to turn it on, something is wrong inside and you need to send it in.

If the unit fires up fine with the speakers unplugged, then you have a short somewhere in your speaker wiring and the amp is (rightfully) protecting itself.

Good luck.

Re: onkyo reciever keeps shutting off

If it works with the speakers removed, take a Volt Ohm meter and test resistance on each speaker wire pair to narrow down the culprit.

When did this happen??? Did you make any changes??? Was it working before???

I agree with Anthony, if the AVR works with the speakers disconnected, check all wires to see that they're not touching; maybe a staple or nail cut them and there making a short circuit

Then it must be the AVR which has developed a fault and that will need to go in for repair, some sound advice from Anthony in the first Instance for fault finding

I hope you get it sorted quickly!

Re: onkyo reciever keeps shutting off

Some units have a factory reset procedure that usually involves holding down a button for 15 seconds or holding the power while you plug it in. It wipes all the user settings, but puts everything back to the original state.

Not likely to fix it, but worth a shot in case this is an internal "software" glitch. Hopefully someone here knows it for Onkyo products and can help. It may even be in the regular user manual towards the back in the troubleshooting section.

Otherwise, back for repairs. Might be covered under warranty. Sometimes they get extended (due to a known fault) or the CS rep is nice and they honor it anyways. I had my Marantz fixed out of warranty several years ago. Cost me $280 total to replace two output stages (2 channels blew in the amp section). This was local, though, no shipping required.

Good luck.

Re: onkyo reciever keeps shutting off

The reset procedure should be in the manual, mine is but i've got a Denon. If not in there check the website for resetting. I really hope this will help but i have a good feeling it's an internal problem beyond a glitch. Good luck and let us know how you come out.

Re: onkyo reciever keeps shutting off

Did you follow this procedure??? (Is in the manual page 92)

Can't turn on the AV receiver
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 set the volume to maximum. If the AV receiver
stays on, set the volume to minimum, disconnect the
power cord, and reconnect your speakers and input
sources. If the AV receiver turns off when you set the
volume to maximum, disconnect the power cord, and
contact your Onkyo dealer

I also found this to reset AVR...
