how are your four outside speakers hooked up? If you have four speakers hooked up to only two output channels on the receiver, the receiver is sensing a short and shutting down to avoid damage to the amp.
too big a speaker load,unit sensors shut unit down when speaker impedance gets too low . and draws too much current at hi volume.A bad woofer or tweeter voice coil burned by sudden excess volume can cause this,also partially shorted speaker wires.
It looks like your receiver's high-speed protection circuit is being activated. It is definitively not a fuse. When a fuse pops, you have to physically replace it. When the protection circuit is activated, the speaker output is cut off and the power supply indicator flashes. There are a few reasons why this happens:
1.- Your speaker wire connections are loose. Whether they are banana plugs or bare wire ends, make sure the speaker terminals on the back of your receiver are tight using clockwise turning. 2.- Verify that your speakers have an impedance between 6 and 16 ohms. Your receiver was designed to work with that impedance range. Any impedance lower than 6 ohms will activate the protection circuitry. 3.- The receiver is used at high volume levels over a long period, which results in an extreme temperature rise. Improving the ventilation conditions around the unit might help alleviate the problem.
If after complying with these suggestions, problem is still present, you might need to have the unit checked by a professional for possible circuit failure. Hope this helps. Let me know.
If you have your reciever in an entertainment center that is enclosed or a tight fit for the reciever you need to remove it and put it on top of the center. I have a VR407 and it was doing the same thing. This keeps your unit much cooler and the overheat relay will not turn it off. also I found it much easier to add or wire components much easier.

When speaker systems A and B are used separately, speakers with an impedance of 6 to 16 ohms can be connected for use as front speakers
Be careful when using two pairs of front speakers (A + B) at the same time if their impedance is less than 12 ohms.
The protector circuit may be activated of the set is played for long periods of time at high volumes with an impedance lower than specified are connected.
That may be a clue to your shutdown problem. Disconnect that speaker and see if the unit still shuts down. If it does not, then there is a problem with this speaker,or the wiring going to this speaker. If the unit still shuts down, disconnect each speaker at a time to see where the problem is. If none of the speakers seem to cause the shutdown problem, there is na major fauly in the amp circuit, so the amp will need serviceing or replacement. Good Luck
