You could buy a universal remote control and try the following NAD audio remote codes to program it with:
NAD
575 773 975

I read somewhere else that the 'Supplied Code for NAD receivers' was 033, but cannot confirm this. Try the first 3 first.

Universal remotes tend to be pretty cheap, certainly cheaper than buying one from NAD.

Good Luck

Your problem is a common symptom of loose connection or cold solder and cleaning problem this is the main caused of no sound or automatic shut off for how many seconds..Cold solder issues - each component is soldered into small holes on the printed circuit board which in turn connects said component to the other components. Due to time, heat, use, some solder joints would be cracked or loose. It is possible that the cold solder is still minimally connected (hanging by a thread). When the receiver turns on heat would be generated which would be sufficient to further loosen up the solder joint to the point it no longer provides electrical contact. Jarring the unit creates movement inside enough to re establish the contact, sometime good enough sometimes not enough. Again, since the unit still operates (sometimes) then it is highly probable that there are no defective components. As you have surmised, it is possibly a loose connection, solder joints are "connections" except that molten soldering lead is used to attach/connect the component to the board, "loose connection" in this sense is equal to "cold solder". Again on the assumption of no defective parts, then seeking a more experienced buddy for the soldering might be to your advantage. This is of course in addition to the possible electrical hazards when repairing.... Good luck: Regards, VOTIT

Sometimes manufacturers change codes from time to time and functions that the remote controlled yeasterday can't be controlled today. You might be able to get some functionality out of another universal remote with a more extensive library of codes available. I understand your frustration - I have a bunch of useless remotes as proof.

I have a T754 which has worked great since day 1 - then i lost IR control. Checked my remote and it is putting out the correct codes and works with another NAD Recv fine. The problem must be in the RECV...


Batteries are flat or incorrectly inserted

• IR transmitter window on remote, or IR receiver window on T 754 is obstructed

• T 754 front panel is in very bright sunlight or ambient light

Hello Robert,

If the standby/protection indicator on the amplifier blinks when you specifically press the volume +/- key, it obviously indicates that the unit is receiving the remote's command.
Try the following while pressing the volume key on the remote:
1.- Put your ear as close as possible to the volume control knob and listen for the sound
of a motor spinning, if you hear it, the volume control assembly needs repair. If you
hear no sound, proceed to next step.
2.- Gently rotate the volume control knob on the amplifier unit (it might be stuck and
needs a "little help").

If none of the above applies, the unit needs to be opened and troubleshooted. I've seen many instances where the volume control motor was not properly connected to the board or the assembly was put back incorrectly (specially in units that have been opened to be refurbished). I've heard NAD has a limited warranty for refurbished items. It might be wise for you to check before sending the unit for repair at your expense or trying to tackle the problem yourself. Hope this helps.

Sounds like a low voltage to the front panel as the indicators are there such as control window illumination is dim and the remote does not function.
The remote sends an invisible signal to a detector just behind the front panel and if the signal from the remote is nice and strong from your new batteries in the remote then it must be the panel electronics.

I have found that if you clean the output panel of the remote with a damp cloth and the same to the front panel glass you may be lucky. Just Damp please not dripping in water!!!!!

If ypu keep the amplifier system very clean then this wont be the problem...But this action has worked on TV's with remotes...

If this doesnt work then a service is due....sorry....no quick fix..

Cheers YOU BEUT
