Question about Audio & Video Receivers
I have a NAD T 773 receiver and it makes a loud sound like "bang" and shuts down completely. Could not operate from remote or front of unit. Red light upper left corner of unit came on. Powered down from front of unit and unplugged for a few minutes. Plugged back in and started unit with the remote and it turned back on. Sound was very bad so turned unit off with remote and back on again and sound was ok. This happened a few days ago for the second time and do not know when it will happen. Unit is enclosed and nothing is around or on top of it so there is good air movement. Unit is still under warranty but a massive pain to unplug all and replug again. Could it be a overheating problem? Should I take it in for service? Let me know what you think. Thanks
You said it's bang and shut it off, try also to check the current requirment of your unit maybe current req can't stand for your loud audio.. peace!

You said Unit is enclosed!! Does that mean it is inside something? Receivers & Amps need to have a clearance above them so air can circulate, otherwise you'll have an overheating problem. You also might have some of your wires crossed which will cause the Amp to shut down. Look at all your connections and make sure they're correct, including speaker wires.

No fix to this problem. When my T763 had the same symptoms I left it with the dealer who sent it on to service. It ended up being scrapped. So I'm afraid this is the end of your receiver unless your techies are better than the ones who worked on mine.
