Fuses are OK, does the same whether connected to speakers etc. or not. Relays click allright. I am experienced with electronics..

Check all your cables, not likely but just in case.
Try removing all but two. Left and Right. Does it still happen,
If you can identify the speaker channel try swapping the speaker if possible.
It sounds like one of the speakers has an issue, could be a short in a cross over or speaker coil. If true the speaker is drawing too much current and causes the protect circuit to trip.
Depending on the quality either replace the blown speaker driver or purchase new ones.
If the speaker is not the issue it could be an issue with a power amp. Best to take it in for service.

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

SOURCE: No signal from sub connected to NAD T760 in test mode.
Try using front pre out to the sub from the receiver. the crossover is in the sub anyway. If this works change your settings on the receiver and test again. If sub is still inop, could be an internal issue with the sub amp. Does your sub amp have an on/auto/off switch or light? check that as well. Hope this helps, if you need further assistance, send a reply and I'll help some more

Check to see if one of the Tape Monitors is ON. Turn it OFF.
There's supposed to be a pair of jumpers between Pre Out and Main In. Are they there? If not, install a short RCA cable pair.

Have you looked at the manual? There is no internal source that would produce 7.1 audio other than the test tones. Attach a multichannel source according to ITS manual.

Check them first and inform me which one has blown out. I'll give you detais after that. OK.
Generally speaking, an amp protects itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.
Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.
You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.
If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.
If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.
