No sound and red power light on NAD C372


I haven't talked to my dealer or NAD yet about this problem, but I wanted to check if anyone has had a similar issue with their NAD or could identify what's wrong. I usually leave the C372 powered up and on standby, but after powering down and unplugging the unit for a couple of days when I wasn't around, I powered it up again to find that it provides no sound from any source, into speakers or headphones. The power light glows its warning red, but I've checked all of the potential issues in the manual (speaker cable shorts, overheating, speakers selected, tape monitor not selected, etc.) and all of that's been OK. I powered it down, disconnected, checked, and reconnected everything, powered it up again and still the same thing. I've done this numerous times, tried different sources, and so forth. This happened once before, a few weeks ago, but when I powered down and up again it was fine. Any suggestions?

The amp is only a month old, and I'm using it with Vandersteen 2ce Signature IIs and Sennheiser HD 600s, with a Marantz changer, Playstation 1, and Technics TT as sources. Cabling is Tributaries and Monster. I've been very pleased with the amp and with my system's sound as a whole, and I've also owned other NAD integrateds (302, C325BEE) in the past without incident. Thanks for any input!

You lost your signal to your outputs, which indicates that a signal path is open.
the problem can be twofold:
1. lost one of your voltage supplies that biases your component in the signal path.

2. defective component in your signal path. When you had the same problem but you managed to have it work indicates that the component was starting to break down at the point and now has completely broke down.
Pound on the various area of the case top and bottom and if you managed to bring back the signal, then you have a cold solder joint. But I suspect that your component is bad.
If you lost your signal to both your outputs, That would be another problem, probably a mechanical problem. (switches)

either way, Best for you to send your instrument back for diagnostic by the company. I dont think there is anything you can do to bring it back. Like Xti said, most components die the first 90 days, after 90 days, you can have confidence that your system will last a long time.
