NAD AV713 receiver won't power up

In the past couple weeks, my NAD AV713 AV receiver will switch off after about two minutes, after which I just press the Power button again and everything will be OK. Last night, it decided to die on me. Could it be a burnt internal fuse? There was a thunderstorm in the day but nothing else blew or tripped. If it is a fuse, where is it located? Haven't had a reason to open up the unit so am clueless. Thanks for any info.

    One of my Sony A/V receivers has somewhat the same problem. I turn it one. Gets power then 30 seconds later powers down.

    I assume there is a fuse burned out. I did crack the case but did not see any internal fuse spots and there are no external ones.

    This is about 5 years old and the silver finish models.

My onkyo HT RC330 will not power up at all. Have had problems past couple of months with starting it but if you played around with swith it would start. Now nothing.

Try resetting the AV receiver To reset the AV receiver to its factory defaults, turn it on and, while holding down VCR/DVR, press 8 ON/STANDBY. "Clear" will appear on the display and the AV receiver will enter Standby mode.

It is possible that the protection circuitry has been activated. Remove the power cord from the wall.. Disconnect all speaker cables and input sources, and then leave the AV receiver with its power cord disconnected for 1 hour. After that, reconnect only the power cord and set the volume to maximum. If the AV receiver stays on, set then the volume to minimum, disconnect the power cord, and reconnect your speakers and input sources. If the AV receiver turns off when you set the volume to maximum, disconnect the power cord, and contact your dealer.

If the standby light is lit it and the unit will not boot it is most likely that the protection circuit has been activated. If there is no standby light then check the fuses. These units check that the power supplies are operating near specification. If a capacitor or resistor in the circuit, or a broken solder connection the unit will shut down. Because of the temperature the thermal cycling around the power supplies a broken solder joint can occur. This will make for an intermittent operation.

Hope this helps.

My NAD T747 keeps shutting down in Protection Mode at 6db when it used to go much louder. I cleaned the unit. Still nothing.

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 !

How to connect ONYZ home kit sirius to a NAD T775?

Try a factory reset of the receiver.
To perform a factory reset, press and hold the MENU and SOURCE buttons until Factory Reset is displayed. Then Power Off from Back panel for 1 minute and power up normally.
You may have damaged the receiver if you did not power off before installing the Onyx module.

You don't say if all speakers are silent or just the ones to the unspecified NAD power amp. Do ANY speakers work regardless of which device powers them? Could the NAD be the problem?
