SOURCE: I have Sony STR DE845
If you consult the card that came with the remote, you will find several codes for "Sony". You will need to experiment with each code until you find one that will power the receiver on and off. Then you will have control of the receiver. If you don't have the card, then go to the web site and download a copy in PDF format from there. I have a lot of Sony stuff, and I have found that the codes varry according to the year the equipment was made and its function.

Generally speaking, an amp protects itself from heat, shorts and overloads.
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.
