My AV Receiver went into protective mode

Something happened, and my Onkyo TX-NXR506 (2008 model) went into, what I found out is a protection mode. Basically, it attempts to get powered on but ater 1-2 seconds goes into "Suspend".
I disconnected everything and kept it completely off for 2 days. It did not resolve the problem.
- Does anyone have any advice on how to get it back to life?
- Is it worth to attempt to fix it ? what would be involved ? I do not have any special electronics tools around to test the voltage at various components, etc..,

Onkyo TX-NXR506 or TX-SR506 ?

Onkyo's TX-SR506 operating manual provides the following instructions:

"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."


"If you cannot resolve the issue yourself, try resetting the AV receiver before contacting your Onkyo dealer. To reset the AV receiver to its factory defaults, turn it on and, while holding down the [VCR/DVR] button, press the [ON/STANDBY] button. "Clear" will appear on the display and the AV receiver will enter Standby mode. Note that resetting the AV receiver will delete your radio presets and custom settings."
