I have a NAD T773 that seems to be working in every way except there is no power to the speakers. As a pre-amp, it works just fine, powering external amps that is. But with the connector pins back in and all the settings still the same, there is no sound from any of the speakers. I guess it is time for taking it in to be serviced, but I cannot help but wonder if there could be something simple that could save me some time and money (3 years old). I have gone through the on-screen menus and found nothing amiss there. Any ideas?
Hi Tahoe; it sounds like a power supply problem to the power amplfiers section of the receiver. The problem sounds like it is common to all amplifiers. If you are looking under the case of the receiver, I would look for a possible blown fuse that could be common to all amplifiers. If there are separate fuses to each of the power amplfiers, I would see if they are ok or blown as well.
