NAD T763 shutting down in certain modes

SOURCE: Right surround channel not working in some modes

I had the same problem with the right channel.    It turned out to be a broken wire inside the receiver; it can be found connecting from the main PCB to the card for the 5.1 board.    After repairing the broken wire, it has worked fine.   

The harness connects the 5.1 low level signals to the board which are then redistributed to the amplifier section.     It is a bundle of wires in gray casing and with red, black and white wires (with shielding).

Find the offending wire, repair or replace and it should be fixed.

Hope this helps

Have you tried doing a factory reset?

1. With unit powered ON, press the VIDEO and TONE DEFEAT buttons.
2. Display will show "AH RESET DONE".
3. Power off (from rear panel switch) and back on.

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.

SOURCE: How to reset a NAD L54 DVD reciever?

This is the technical solution, you have to open the unit:
Locate IC33 and connect pin 6 to ground, connect power, and then remove the ground connection at pin 6.
The unit will then boot up in factory default.
