Question about Sony STR-DG810
I connected my STR-DG810 to a Bose Acoustimass 10 system and get no audio out of the speakers (but the audio on the TV speakers work). I have my Comcast HDTV box connected to the receiver, and the receiver to the TV via HDMI cables, and nothing else. I have triple-checked all the connections, and also unplugged and re-plugged in the Acoustimass to the AC outlet. (There really is no way to tell if it is being powered.)
Go into the menu settings by pressing "Receiver" --> "6-Video" --> "HDMI Audio" select "Amp," not "Amp+TV"
Yeah, it makes total sense to have a very important audio setting in the video menu.

Overloads can be from excessive periods of high output 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 hands-on tech.
