Hello, How long have you owned the receiver for and when did the problem occur?

Thanks for the reply. This can be caused by a hardware failure in the receiver in many cases, however it would be worth trying a hard reset.

First disconnect the receiver from power then disconnect all speaker wires from the unit. Then plug only the receiver back into power and attempt to power it up. Let me know what happens.

If this does not work then the Onkyo has a hardware failure in the power supply circuit and requires repairs. The average cost for this type of repair is in the $200 range, which in most cases is more cost effective to purchase another receiver in lieu of repairs.

Your suggestion didn't resolve the problem.Keith

Keith, It wasn't merely a suggestion- it was all you can try on a user level to fix this. If the receiver is still not powering up beyond 3 seconds and then clicking off, it's a hardware issue as mentioned above.
