It could be a heat issue, is the receiver able to get air to cool itself? Also, a bad speaker or mismatched speaker may cause this. Sometimes hooking up extra speakers may cause this. Other than that, it would be a service issue.

The clicking is the sound of a bad relay. A relay is an electrical switch that opens and closes under the control of another electrical circuit. There is no user solution for this. You'll have to take it to an electronics repair shop (~$150) or dump the whole unit.

SOURCE: NAD 712 Display unit

On my system the bulbs burned out some time ago. Today, I bought a pair of 12v micro lamps at Radio Shack (part 272-1092). Then removed the board behind the display and replaced the bulbs. This required some soldering. The bulbs have held up for more than 6 hours, so I do not think they are going to burn out.

SOURCE: My NAD T743 will not switch on

Hi, have you checked the power button in the back to see if it got pressed by accident? It's a round button located right under the speaker inputs in the back.

1996 cougar turn signal switch or hazars dont work


Im not sure if you mean if bolth or one system isn't working If bolth the problem is likely in the fuse box if one the sending unit located in the center on a 96 is likely the problem. You have to go up and look for the relay center . The units just unplug cost about 10 dollars and are bolth the same interchangeable. If not this then its the muilty funtion switch on the coloum or a bad connection between the fuse box and the relay center or the muilty fuction switch Wiggle wires around to see if it starts to work even for a second that means its a bad connection and the switch and relays are working

NAD T743: The digital channels stop working after a short time.


Hmm, sounds similar to my problem. Analog input and FM seems to work but all coax/opto input are dead ( for me there isn't a buzz).
Have you, fredrik648, solved your problem?
Anyone with ideas what to do?

Thanks

Using NAD t743 with Panasonic DMP-BD55


The reciever you have has 5.1 inputs at the backof it.The only way to get Dolby True HD and DTS HD is to run the 7.1 analog out from the bd55 to the nad. You'll have to leave the 2 rear surround open on the bd55 leaving the remaining 6 connected to the nad. The digital coax and the optical will not transmit the hd data, only the analog out will. Run a hdmi right to your HD tv for picture bypassing your amp. this will workfine and you'll have the audio you want. You,ll have to change the input settings for dvd in your amp to 5.1 to recieve the audio.

Power on T743


Just had my t753 in bits... sounds like its overheating to me. Check that the fans on the bottom still turn and aren't clogged up with dust. Make sure that it has plenty of ventilation.

hmm, also try unplugging everything and leaving it on and see if it still freezes? ie check you're cabling is ok, there are no shorts from bare speaker wires etc...

Could try resetting it too? (in each case hold the buttons for 5 seconds then release)
- Firmware version: hold video 6 and tone control
- Reset DSP: video6 + tone defeat
- Reset completely: video6 + right source button (this will wipe all settings - hold for 5 seconds, release and then unplug from the wall or turn off with the rear power switch)

Turns itself off


NAD Technical Bulletin T743-H2005-06 describes the problem "Unit may shut down, shortly after turn on".  Reason: There is a diode on the standby board that maybe operating intermittently.  Solution: Locate and identify D756 on the standby board.  Change only if the diode is a 1N4148.  Change from a 1N4148 to a 1N4004 or equivalent.  
It is located near a transformer and some fuses.

Does not respond to remote control


I have had the T743 for about three years now. The first unit which I got from the local shop was doing exactily like your described after couple of minutes use. Well, I took is back and got a new one covered by the warranty.

Unfortunately I never got any explanation to this problem from my local shop or anywhere else, so I guess the only way is to contact your local shop.
