A PROTECT message displays when I try to use this receiver and locks out the ability to use it. How do I get rid of that message, I am not a technical person. Thanks hope you can solve this, the usere manual does not address this message. NAD AV-716 Receiver
I had this same problem.... twice. The system protects itself form frying because you have crossed wires while the system is on.
Prevent this by: Never touching or messing with wires when your system is on. Always unplug before messing with them.
Also, trial and error - locate the bad cable. Never use old beat up cables, use clean ones without breaks or sufficiently fixed with electrical tape.
Solution: I had to send my unit back to Sony. They were nice enough to take it off of protection and send it back (both times). It took a little less than three weeks for me to get my unit back (not too bad all things considered).
Hope this helps, it was a nightmare til i figured it out. Very frustrating especially with a new unit
Just called Sony and they were very helpful. It is either an issue with having a surge protector or a speaker connection. I plugged my receiver into wall without protector with no change. Once i removed all of my speaker connections to receiver, the problem went away. Upon reconnecitong speakers i noticed that my center speaker wires were touching and shorting out connection. Once i fixed this everything was hunkey dorey.

Modern AV receivers such as your NAD have protection circuits to prevent damage when there is a short on the speaker terminals. Look carefully at the speaker connections on the back of the AV receiver- for example, the speaker cable for front left speakers labelled + and - : there should not be any stray strands of wire that connect from + to - ; this would be a short circuit. Check each of the connections on the AV receiver as well as on the back of each of your Speakers themselves. Also ensure all connections are snug (do not use pliers). If this does not solve your problem, you may need to take your AV receiver on for a service checkup. Good luck !
Hi, try powering up the unit with out any speaker connected if it still goes to PROTECT try factory reset if possible.
To reset the AV receiver to its factory defaults, turn it on and, while holding down VCR/DVR, press ON/STANDBY. "Clear" will appear on the display and the AV receiver will enter standby mode.
If this does not fix your problem you should take your unit to service . :)
Hello Check the connection to speaker with this amp, for any short or any other fault. disconnect the outputs, ie, speakers from the amp, and switch it On, and see the protect display comes or not. If it comes, the fault is internal and the set need service. Your M3 dual Mono integrated amp, is of high output power and its outputs are protected against any overload or short circuit. If the system detect any among this condition specified above, it will show protect mode display. Never load this amp, as protection display is there, as it may damage the speaker or its internal power amplifier section circuits, may cause more money to get it repaired. OK.
It sounds as if you are still infected. If you have acess to another PC you can download and burn the F-Secure rescue CD which will scan your system before your OS boots (you need to set your BIOS to boot from CD).
Your receiver is basically going into protect mode.
The Denon AVRs contains a microcomputer for signal processing and control functions. In an unlikely event, it may cause it to lock up. Unplug the power cord from the wall outlet, wait for 10 to15 seconds and then plug it back again.
But, before you do than, please also check your speaker cabling again. Make sure that all of them are seated properly, none is touching each other or the body of receiver. Take out all the wire and put them back again if necessary.. Some times even a little tiny frayed wire touching the receiver could trigger the protect mode. Be careful, since protect mode is sometimes not fast enough and it could blown a few trasistors in the power circuit. Just check your speaker as well....whether they play all right thru another receiver or amplifier. its posiible they might be shorting inside. A little frayed wire could also trigger the protect circuit in your receiver. I hope this should solve your problem.
If you still can’t resolve the issue yourself, try resetting the AV receiver/AV amplifier before going on to opening the Receiver.
Hope you can sort out your problem with the above trouble shooting. Let me know if I can guide you further. Best of luck. Thanks for using FixYa!
i would like to inform you that I mail you a letter by post and you will received it within two weeks time. Regarding NAD AV- 716 details and spare part requirement and also i would like to remind you that my second letter stated all requirements etc.dated 8th march 2013. Please refer to the given below Email address. ( email@example.com)
The output section is probably in protect mode because a problem was deteceted internally. Please update this with the specific model and I'll try to provide details. Please note that there are variants for a number of NAD receivers based upon the serial number. Please post the serial number as well.
