Your receiver is shutting off and going into what is callled "protect mode". This typically happens when you have +/- wire touching somewhere. The usual culprit is in the bare wire in the connection terminals in the back if the receiver or speaker.

Other things that can cause this....

- Problem internally with the receiver. Perhaps your friend gave you his broken one?

- Over heating. Is it in a cabinet with little air clearance or other really hit electronics in there with it? The #1 culprit here is the cable box getting very very hot and too much stagnant air.

- + or - connections wired backwards (out of phase). This would mean that you have maybe the + speaker wire wired into the red on the receiver, but the black on the speaker. Or vice versa. It could be 1 or all of the speakers causing this.

- The receiver or speakers are from a "home theater in a box" and will only work with speakers that have a particular impedance. Meaning: Your regular speakers (or HTIB speakers, either way) are causing the receiver to shut down. This doesn't mean anything is broken. The amplifier in the unit might only work with a specific type of ohm rated speaker. Typical with HTIB units that come as a package with their own speakers. These are usually very cheap and not meant to be mixed and matched very easily. A name brand stand alone receiver wouldn't typically have this problem. Nirnwould brand name stand alone speakers. However, if they came as a little package, they very well may have compatibility issues.

PM me if you have problems trouble shooting this and I'll shoot you my number and we can set up a time where you can call me and I'll walk you through setting it up correctly. Or, post the model numbers to the receiver and a speaker and I can tell you if they can even work at all.

My initial guess is it is either bare wire touching, or something is from an "all in one" home theater in a box type system and isn't going to be compatible.

Which is where I think I ran into trouble with my Onkyo HTS-3800.  When one of the fronts blew, I upgraded to Cerwin Vega XLS 6 fronts and center channel, and some used Cerwin Vega AVS Sat 4s for the surrounds.  Yeah, I know.....not the best clarity, but for the application I use them for....which is LOUD....they work great.  Problem is, they (the 6.5s) aren't very efficient with peak power at 125 watts.  You combine three of those with the unit having to push a passive 8" sub to boot.....I guess I'm surprised it lasted as long as it did.

The Yamaha handles them with ease, barely gets warm with the fan....and I also added a powered 10" Klipsch sub to the mix, so the receiver isn't having to handle that as well.
