Question about Audio Players & Recorders
Protection is very likely caused by an over heat condition, even with the fan working if the receiver is in a very enclosed place that warms up and is not ventilated it will cause the problem. The solution is to provide more ventilation so that the receiver can cool itself properly.

Protect mode will kicking whenever a fault is detected.
Causes that can start protect mode are:
Electrostatic harges on internal circuits.
Leave the unit unplugged for power for one hour or so, this will allow discharge.
Bad speaker wiring.
Check speaker wiring, try unplugging and plugging back, or start after removing one speaker at the time.
Internal fault is the natural cause for protect mode. If all the above did not work, then the problem is a blown component or an internal fault. In this case the unit must be taken apart , tested and repaired by an experienced person.
If the unit is less than one year old, or if you want to get service, call Sony at the phone number listed on the product documentation.

I have HT-X40 home theater, but my problem seems similar to yours. It's related to overheating. First check the fan and air flow from it. If it's OK, the problem can be inside the unit. In my case one of the output filter capacitors got broken - it had a crack on its body. Replacement of the capacitor fixed the shutdown on protection.
Another question is what damaged the cap. Preliminary I consider placement of the capacitors as a possible problem - they are too close to the output inductors which can get relatively hot even at normal working condition.

the protect means a circuit overload check that you dont have any wires for your speakers touching or backwardly installed if those are all fine you may have blown a fuse inside the receiver.
