Thought I'd share my experience with the NR1007. HDMI board finally gave out about a month ago. No network, none of the DSP/speaker icons lit on the left side of the display, etc. Before that the audio would drop out on occasion or while powering on. All the functions, OSD, etc that didn't require sound or the network seemed to work fine.
I E-mailed the Onkyo support people about the problem. Got a response the next day asking for more information: name, address, S/N, bill of sale. My receiver was just over 6 months out of warranty when I sent the mail. They generously gave me a one time extension of the warranty to get the unit repaired. Dropped it off at the service center they told me to use Monday. Got a call today (Thursday) that the HDMI board was bad, a replacement board had been requested Monday, and that the unit was now fixed and ready to be picked up. I was honestly expecting this process to take more than a week, not 3 business days excluding the 3 days spent sending/receiving emails.
After some of the horror stories I've read Onkyo has definitely improved their customer support tremendously. I really can't imagine this repair going any quicker than it did. Not to mention that it was out of warranty and they didn't have to do anything. On the other hand the HDMI board failures almost seem worthy of a product recall. Glad to have this thing back and working. TV speakers on a flat screen just don't quite sound the same!
