I have an NAD M# that was working perfectly when the power went out for a moment (the breaker was accidentally shut off). The unit was also plugged into a high-end power conditioner so there shouldn't have been any power surges. When the breaker was switched back on, the M3 was dead. No power light of any kind. No sound of a relay. Tried different outlets. No joy.
Suggestions?

Let me know if you can get working and want to sell. I need a parts donor for a project m3 as the replacement boards are no longer available.
Thanks!

Hi!
If you're lucky, only one internal fuse has blown.
In the worst case, the standby circuit has failed (it can be repaired cheaply).
In any case, a qualified repairman is necessary for the repair, because it is an expensive and complicated device and it is easy to cause even more damage.

Hi!
Try factory reset, i don't know model M3 how to do it, but in M33 in back side have reset button (hole).
In other model of amplifier must press and hold 2 button combination in front panel and put plug in outlet.
