Question about Audio Players & Recorders
I'm getting no sound from speakers. How can I factory reset to solve problem, before taking to shop.
To reset theHT-R520 to its factory defaults, turn it on and, while holding down the [VIDEO 1] button, press the [STANDBY/ON] button. "Clear" will appear on the display and theHT-R520 will enter Standby mode.

Does it only happen when its being stressed (played really loud)? Is it hot? If so, is it well ventilated and away from other heat sources?
Somewhere in here is the answer.
"The AV receiver turns off as soon as it’s turned
• 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."
That last sentence is misleading. I don't think they actually want you to play an active signal at MAXimum as a test. I think they mean with all sources attached and an idle one selected, like CD, crank the volume knob. If the amp is not in Protection mode you should always be able to detect some hiss up close.
For another thing, if it shuts down only with speakers attached the problem could be outbound at one or more of the speakers. I would isolate that piece somewhat before throwing my hands up and calling Onkyo. Make sure that the speaker cables are not shorting. Disconnect certain speakers and try it again until you figure out which one(s) are involved. Then it could be the speakers.

if you are good at tinkering then you can pulol the top of the receiver and check the fuses on the board to make sure that they did not blow if not then it would be wise to take it to a repair shop to have your receiver checked out and serviced

NEVER USE MAXIMUM VOLUME FOR TROUBLESHOOTING. Carefully examine the front panel for clues like a misplaced Mute or Tape Monitor control or Multichannel Analog Input selected. There is a good chance that a common control may have developed a high-resistance or 'dead

Turn the volume control to something medium.
The errant switch, control or condition may change and you will suddenly release the amp's full power and possibly destroying your speakers. If a signal isn't audible at 1/2 volume it's probably not there.

That depends what's really wrong.
Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.
Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.
You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.
If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.
If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.
