Or else the HDMI board failure or HDMI switching issue. very common issues with NAD av receivers & HT processors. NAD home theater gears (AV receivers & processors) are well known for that. they are buggy, so are Rotel's & Cary Cinema 11 & 12 processors.
Don't get me wrong they all sounded great especially for music but are buggy.
Unlike those Japanese AV receivers & processors that are reliable and aren't buggy but don't sound as good as the NAD or Rotel or the Cary Cinema.
