Question about Sharp Audio & Video Receivers
The protect mode is an indication that the unit has detected a problem in the final stage of the amplifier. This can be caused by a shorted wire as indicated by toddg, but one the short occurs, there usually is internal damage that the removal of the external short will not fix. This problem can also occur without crossing the wires because of component failure. If you can post the make and model of the unit in question here, I can give you the most likely defective parts along with their replacement costs.'

This denotes a short in the wiring or a cross of the negative and positive polarity of the speaker wires. Check to make sure the speaker wires are not touching anywhere. This would be the most obvious place of the wire cross. Look for any fray or anything that is touching another cable.
