So I hooked my new system up last night: NAD T742 A/V surround receiver NHT SB-2s and SB-1s NHT SuperCenter Dayton 10" sub Two minutes into testing it out, the NAD powers off. Just shuts down. Repeated attempts to power it back on result in the green power light on the face of the receiver flashing, but no display in the window — nothing, totally blank. It switches on and off with the remote, but other than the green light coming on, there is no display and no output to the speakers. What did I do? I thought maybe I blew a fuse in the amp, or that the amp just couldn't handle the power. Can that be? The amp is rated at 120V 60Hz; the sub at 150 watts, and the speakers at 8 oms and 15 - 125 watts for the SB-1s and 15 - 150 watts for the SB-2s. All speakers were hooked to the appropriate inputs on the receiver, and the sub went in the audio pre-out sub input. Does this sound like a blown fuse (does it even have a fuse), and why might this have happened? Any advice appreciated.
