I've had an Integra DHC40.1 for about 10 months, and it went silent back in early November - no sound from any input, including the tuner.
These things happen, so I went through the process of requesting warranty service and sent the unit in.
Integra told the the repair center that the part needed was unavailable, with no date foreseen for it to become available, and the service people requested that a replacement unit be authorized.
The service people are doing what they can. I wish I could say the same for Integra. Over a month has passed, and with the holidays it would be good to be able to have sound with the movies in the media room.
I've called the Onkyo/Integra service line repeatedly, and sent email from the website. So far, over 3 hours on hold, going into their 5pm ET closing time twice, and being disconnected once. Easily the worst service experience I've had in 40+ years of heavy electronics ownership.
The dealer says they are pretty notorious for this, and they would expect another month to go by before I hear from anyone there.
This is (allegedly) a "premium product", but the service really stinks. Out out 11 months of ownership, it's been out for service for over a month, heading toward two.
Newsflash - Another hour on hold just ended with a message that the office was now closed and I should call back! It offers to let you enter your number, but, amazingly, this feature doesn't work - I tried it twice using a landline phone and a cell phone, and it misses digits in when you put in your number.
Word to the wise - Buy Marantz, Anthem, Anybody But Onkyo or Integra
