TX-NR609 power on issues

We've recently been experiencing issues with the receiver not staying on when we initially turn it on with the remote. We will press the power button and the receiver will act like its going to turn on (lights come on and words on the display) but after a second or two it shuts off. When we go to turn it on the second time there are no issues and it stays on just fine. We've checked all the wiring and don't see any loose connections. Any thoughts on what the problem might be? Thanks!

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.
