Kenwood equips its receivers with a protection mode to safeguard them. Your stereo receiver is going into protection mode because the receiver has an internal short, a speaker is bad or the speaker wiring has a problem, such as incorrect wire gauge or bad connections.
Turn off the receiver and let it cool for a few hours; then try again. If the protection mode warning doesn’t go away on its own, press the reset button. If that doesn’t work, disconnect the power lead from your receiver for 30 seconds and then reconnect it. If it still doesn’t work, it’s time to take it to the dealer.
