Some of these units have a circuit protection system that is made with capacitors and/or resistors. The caps can become overheated and eventually wear out. The relays themselves can also become faulty which seems most likely in your case. How is the fuse? Have you check the power form the main power supply to the circuit board? THere should be a label on the inside somewhere that says the DC voltage output. The mulit-meter you use to test it should match the sticker voltage output rating.

NAD T-763 receiver. cannot get surround sound. all speakers work. should the 7.1 and or surround be connected to the receiver and what else. stereo works fine....two front speakers, in stereo mode. ...


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.

NAD T763 - i turned it on and all the lights on the display lit up and stay on. It doesn't work at all !! Any suggestions?


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.

I've bought my NAD C326BEE amplifier almost two years ago, and i got promised a hell of a good quality and that it would last for YEARS. But ever since i bought the damn amplifier, it has been shutting off...


Hi there,
I'm also a Nad fan. I find this pretty odd that you should loose two in such a short space of time. The cutting out is due to the "protection circuit". I would be inclined to get your speakers checked out as if they are faulty or not "matched" to the amp, it will trigger the amp to "protect itself" and shut off.

I have purchased the NAD C320 used. Have been


yes send it back chances are there could still be a warranty on it and that should be covered by it dont mess with it that could invalidate the warranty even if its not in warranty to replace the switch wont cost much.As for the contact cleaner be careful it is flamable and an arcing power button could ignite it do this with the unit unplugged but also make sure its dry after too do not do this unless you find the warranty has expired. Hope this helps

NAD 3150 doesn't play any sound


I, too, have the 3150 and have experienced problems with it. With me the INPUT knob is touchy and needs micro turns sometimes to get both channels to come through. Also, it sounds like the pots are dirty as I get a scratchy sound while adjusting the knob. I have been told that these units are great middle of the road audiophile units. Actually, for the price of a used unit you can't do better. I just had an NAD 2400 THX amp delivered today and am using the 3150 as a preamp. My girlfriend is not feeling well and sleeping in the bedroom, though, and I can't listen to it :( The few minutes I heard of Steely Dan's Cousin Dupree made me bout **** myself (until I got the dirty looks). Sorry I wasn't more help! Goooooo NAD!

T763 Dead


This happens to many of those model. The problem is usually on the power board (if looking down into with the control panel facing your belly... it's the cluster of boards to the left, front of the unit. Look in the top, under the connectors. YOu sometimes have to dissassemble the thing alot to gety to it. Also, on the main board, under all the "cards" (the input/video circuit boards) and near the front (at the back of the cards) tere are heat sink mounted regulators that often need to be re-soldered.

The whole process is a pain, and can take a few hours to do properly, so most repair companies will charge accordingly. Yeah, it's a shame they made them like they did. If it's working, it's a good unit. Aside from these common failures.

Nad c372 prob


The unit is detecting a problem and shutting down in what is usually called "protect" mode. Look for bad connections on the board near the voltage regulators.
