Solved! Onkyo 7.2 surround sound shuts off in 2 seconds

[larryrolson]

I have a Onkyo receiver amplifier 7.2 surround sound. It stays on for two or three seconds and shuts itself off. Anyone have any idea what might be wrong with it? How can I troubleshoot it? Is it something that a handyman could fix it home?

Thank you very much

1. Disconnect all the speaker wires from the back of the receiver. Turn the receiver on.
2. If it stays on then one of the speaker wires was shorted or one of the speakers are bad. Reconnect them one at a time and turn the receiver on. When you connect the bad wire or speaker the receiver will shut down. If after you connect them all if the receiver now stays on then there was a short where the wires were connected to the receiver that you repaired when you replaced them.
3. If the receiver goes into protection with no speakers connected then disconnect all the inputs and other wires and try turning it on again. This isn't likely to make any difference. If the receiver continues to shut down then it has an internal problem that would require a technician. Hope it's under warranty.

People posting questions never mention, this EVER worked before? kinda important.

'Cuz if this is your first time setup, you maybe using low-ohm speakers your Onkyo is unable to handle.

Thank you the theater has been set up for several years and functioned perfectly and the problem with the unit shutting off spontaneously mysteriously developed recently.

I followed your instructions, and one by one disconnected the wiring. I'm not sure what I did but it's working again!

Thanks 1, million
