Wow, really? How long has it been gone at this point? Do you recall which repair center it was sent to? I sure as heck hope mine's not gone for months.
We are FAR from the only ones I've seen online mention this exact same issue with their X700 line Denon, and even in some other lines. I would hope at this point the techs would be like ... yup, we know what this problem is, and just knock out a fix. Guessing it's a bad board. But a problem might be getting replacement if enough of these are bad in the same way they might not have made enough replacements, and everyone moving forward is SOL cause they're not making more. Could be why yours is held up so long, just a guess.
I suppose I should update this...
I received it back two weeks ago. They said they replaced a power supply board and an amplifier board. They said the delay was waiting on parts. The repair cost me $0 out of pocket, fortunately. Rather than place it back in service, I elected to sell it to a friend with a 1 year "SteveDallas" warranty. AFAIK he has not done anything with it yet, as he bought it for a future home theater project he has not started.
So far, the 4800 I bought to replace it serving me well, and I like its feature set better than the 4700. And no, I cannot hear any difference in the DACs.
