Update T187 firmware
I contacted NAD directly and they emailed to me a file to use to update the T187 firmware using my laptop. Alternatively, you should be able to go back to the dealer and have them update it for you. This fixed things for the most part. Rarely I still have a problem, but its all dependent upon how I cycle things on - TV, BluRay player, T187, etc. I did replace my older Samsung bluray player with the integra, but I still had the issue. Leads me to believe its an HDMI handshake issue. One interesting thing to note is that I am experiencing the issues in the 3rd HDMI port. When I switched to the 4, 5 or 6 HDMI ports I had no issues at all. I still had issues with 1 and 2 however. When speaking with the NAD technical rep about this, he was surprised and still suggested I use 1, 2 or 3 as they offer better performance (not sure why), so I deal with the occasional hiccup. When I do have an issue, turning the T187 off and then back usually clears it up and then I'm good to go. Not ideal, but the performance of the T187 has been fantastic otherwise.
