Check the speaker connections. Make sure that all of the speaker wires are properly connected to the receiver and that there are no stray wires touching each other.
Disconnect the speakers. Turn off the receiver and disconnect all of the speaker wires. Then, turn the receiver back on and see if the "protect" message goes away. If it does, then one of your speakers is likely the problem. Try connecting the speakers one by one to see which one is causing the problem.
Check the speaker impedance. Make sure that the impedance of your speakers is within the range specified by the receiver. If the impedance is too low, it can cause the receiver to go into protect mode.
Check for overheating. If the receiver is overheating, it will go into protect mode to protect itself. Make sure that the receiver is properly ventilated and that it is not located in a hot environment.
Reset the receiver. If you have tried all of the above and the "protect" message is still appearing, you can try resetting the receiver. To do this, turn off the receiver and unplug it from the power outlet. Wait for at least 30 seconds, then plug the receiver back in and turn it on.
If you have tried all of the above and the "protect" message is still appearing, then the receiver may need to be repaired. You can contact Sony customer support for assistance.
Here are some additional troubleshooting tips:
Try using a different power outlet.
Try using a power conditioner or surge protector.
Check the receiver's firmware and update it if necessary.
Clean the receiver's dust filters.
Avoid using the receiver in dusty or humid environments.
If you are not comfortable troubleshooting the receiver yourself, you should take it to a qualified repair shop.
