The protect message indicates that the output amp section has a problem. Normally this requires the replacement of the output transistors or the output amp pac. Expect the repair cost to be about $20-$60 for parts plus the local labor rate.

Power problem

If the protect function works but is causing you problems, cancelling the protection function should help, and it will be possible to enter the self-diagnostic function mode. This should disable all functions of the protection mode, excluding the 'excess electrical current detection' feature.

While pressing the "Tone Control" and "Info" keys, try pressing the power key to turn on the power. Keep pressing those 2 keys for 3 seconds longer.

this should activate the Self Diagnostic function, with your Protection Mode disabled.

in this mode the 'sleep' section on the tv's fluorescent display flashes to indicate that the mode is properly activated.

just be very aware, this function is normally there as a safety feature and i cant guarantee that disabling it altogether won't cause other problems down the road. best of luck!

Your receiver probably went into protect mode because you were overloading the output stage with concert blast. In some units, protection consists of fuses that blow; in others protection is provided by thermal shutdown devices.

Take every single cable out of the unit, now power on the unit.

If the power protection still shows then there is an internal fault, usually a short or a component defect.

If it powers on ok, switch off and insert 1 speaker at a time and power on the unit until the protection mode comes on again, the last speaker you have put in has overloaded it for some reason, also as you are trying each speaker use the volume and bass controls to see if there is an internal overload.

Thats as much as I can offer you until you narrow the fault down to the unit or one of the speakers.

Protection displayed and shuts off

are all the speakers good?? discont all the speakers and see if all the lites come on. Then shut off and start to connect one at a time untill the unit shuts down and then you know you have a shorted speaker. If the same thing happens you probably have a power supply or an output stage falure and this should be serviced by someone who is quilified to work on stereos
