Some receivers shut down automatically if a thermal overload is detected or more commonly if speaker impedance is less than specified, i.e, driving a 2 ohm impedance speaker with an output rated for 8 ohms. If you can get the receiver operating long enough, you may see a message indicating why it is shutting down
Activated protection circuitry means that the amplifier is seeing conditions it does not like and is shutting down the power to prevent further damage. Either you have a short in your speaker wires, in your speakers, or a blown amplifier. Disconnect both speakers and turn on the amplifier. Does it still give the error message? If it does, your amp is blown. If it does not, carefully inspect your speaker wires and their connection. Make sure all looks good and reconnect the speakers and try it again. Still get the error message? You likely have a problem in your speaker cabinet(s).
The problem is not with the inputs. This unit is in protect because a problem has been detected in the output section. Try disconnecting the speaker wires and turning it on. If the unit remains on, there is a short in one of the speaker wires. If the unit still shuts down, there is an internal problem that will require repair. It sounds like this is a new piece. If so, it should be covered under warranty.
I sent this TX-SR605 system to an authorized dealer for repair. It seems like it is a very simply problem - the internal set-up mic jacket closed circuit, so the system think the set-up mic is always plugged in (even when physically unplugged it, the system still detect plugged in). And it enters the automatic speaker setup and never quit.
Now I have the receiver back home and tested it. Everything worked O.K. now. It is a pity that this new-bought equipment (just one month) need repair for just a small action of plug in a mic ( I swear I plugged it in very tenderly). It is shame for such a unreliable performance happened on brand name like ONKYO. How can you be confident for an equipment failure in one month.
