Question about Audio Players & Recorders
Your receiver is basically going into protect mode. Check your speaker cables. Make sure that all of them are seated properly and none is touching each other or the body of receiver. Take out all the wires and put them back in again. Even a tiny little frayed wire touching the receiver could trigger the protect mode. It is also posiible something is shorting out inside. A little frayed wire could also trigger the protect circuit in your receiver. You may have to open up the unit to replace a fuse or do some soldering. If you still have a warranty then send it in for repair. Something is overheating inside the amp

When you mean a short time how long is a short time. Also long does it take before you can turn the receiver back on.
It sounds like you have a short on the receiver its self or another device is grounding back to the receiver.
The thing to keep in mind is with modern electronics they do not have a physical switch but they us contact switches. A contact switch works by making a connection to turn on or off.
The problem is if the an extra charge is being applied to the receiver this can cause the contact switch to engage.
To test this unplug all your connections to the receiver. Note most likely the speakers are not the problem so you do not need to disconnect them. However you do want to disconnect all connection including any HDMI cables. I had a case the other day where some on had a bad cable causing the problem. Next start plugging back in the devices to see which one is causing the problem.
If the receiver still turns off with all connection unpluged then the problem is with the receiver its self.
Let me know if you have any more problems or questions

Generally speaking, an amp protects 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. Eure 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.
