Sounds like you have an issue with your electrical circuit. Your receiver could be receiving spikes of current from the electrical wiring in your house.
Review your current electrical situation. Keep in mind that certain outlets are on the same circuit and that running multiple, high-wattage devices on the same circuit can cause issues with some of those devices. Especially when it comes to turning devices on and off.
Many devices take a sudden, rapid charge to power their circuitry the moment you turn the device on. Home audio and HVAC systems are particularly notorious for doing this. Other devices on the same circuit can sometimes suffer influxes of power flow and may either turn off or go into standby mode to protect themselves from the resulting surges.
I've lost audio systems that way... I lived in an apartment building that has wiring most likely dating back into the 40's. I once turned on a space heater on it's max 1500 watt setting and blew my Logitech Z-680 speakers. (The "BOOM" sound that emitted from my subwoofer was AMAZING. I had just blown an amp circuit. It literally exploded inside of the subwoofer. Took pics and everything.)
If you have the means to do so... You might consider re-wiring your electrical circuit. Take into consideration where you're going to run certain devices and wire the system accordingly.
In the meantime, you would want to be sure to buy a HIGH-QUALITY surge protector for the audio system. Spend a few bucks and get a GOOD one with a good warranty on it. Don't use those cheapy ones that we only really use to split the outlet. NOTHING under 1,000 joules.
My receiver sometimes locks itself like that, though. If we have a power outage or the unit is unplugged suddenly, it will keep itself in standby mode until you unplug it, press the power button a few times to discharge any current left in the capacitors and plug it back in normally. Only then will it turn on again.
Let me know what you come up with.

SOURCE: Audio glitch on Marantz SR-19
It's probably not heat due to the Marantz' large frame and heat-synchs.
This could simply be a mismatch of impedance. The amp is 120w per channel, so make sure the speakers can handle this. Check the impedance (ohms) of the speakers and the amp as well. Clipping can be caused by overpowering the speakers, which could damage the speakers in the long-run.
If this is only from 1 source- (i.e.- Blu-ray player or cable) then it could be digital clipping.. This Marantz can decode 96kHz PCM or normal Dolby Digital & DTS. If this is a Blu-ray it may be streaming 192kHz PCM... (but most likely the Marantz will not even attempt to play that audio)
I hope this helps.
