Net help for home theatre problem

Since moving to the new house, I have been having problem with my av receiver. Specifically, it gets very hot under a few hours of operation and is then switched off automatically. This had never happened before. I tried simple internet searching for possible reasons and hence a cure, unfortunately to no avail.

So I posted this problem to a forum devoted to home theatre. I have since recieved lots of helpful advice. While I still have not figured out what exactly went wrong, this experience again demonstrates the immense use of the internet as a problem solving tool.
