My NAD T762 inexplicably stopped outputting Dolby and DTS audio a couple of weeks ago. I've played DVDs and HD DVDs on two different players (digital optical) and an X-box 360 (analog connection), and the receiver isn't able to output proper sound anymore. Stereo music is fine, however. I contacted them about the issue and long story short, am looking at spending nearly 30% of the purchase price just on shipping costs (to an authorized service center) and evaluation fees. This is before I even find out what's wrong with it and decide if the repair is worthwhile. (I'm assuming I'll get hit for return shipping from the service center.) Even if the service center pays for return shipping, the cost of getting it repaired could still keep the overall cost at 30% of what I paid for the receiver 5 years ago. My other option to get it fixed is taking it somewhere locally, but not an unauthorized service center, and hoping I find someone who can solve the problem. But in either case, how much more usage can I expect to get out of the repaired unit? I wonder if I should just cut my losses and get a new receiver (not sure if I'm going to trust NAD again, though).
