I'm really starting to get browned off with this. It seems like almost everyday now that I switch my 626 on, only to find no sound on any input, including the tuner. The net icons also disappear. I have to turn it off at the wall, which is no mean feat in itself getting behind the AV rack, and leave it for around a minute before turning it back on again. When I do this, the Onkyo logo comes up on the screen and "HDMI Initialize" comes up. Theres still 2 years running on the warranty with Richers, and they have suggested trading up with a decent discount for the hassle. But looking back on various forums, it seems this has been a problem over many years with Onkyo amps. Are the 2017 models any more reliable?
