Disconnect rear back channel at the receiver end, turn on receiver and see if the receiver goes into protection mode. If it doesn't than you have a cable or speaker problem.

If it still goes into protection mode, disconnect ALL the speakers at the receiver end, turn it back on and see if it still goes into protection mode.
If it does, the problem is in the receiver. Take it to the repair shop.
If it doesn't, one of your speaker or cable is defective.
