I am a new owner of an Onkyo TX-RZ830. Although I generally very happy with the quality and feature set, this morning I experienced something weird with the receiver. Well, actually since I first installed it about a week ago, I have been noticing some random "relay" clicks, even when the receiver was in stand by mode.
Then this morning I was using Airplay for the first time with my iPhone XS. A few songs in, the music stopped. After some investigation I detected the problem: wifi connection was dead in the Onkyo, status "failed". I tried to turn off and on the receiver, turn off and on the wifi connection, but nothing fixed the issue. During all of this, I noticed that the receiver UI was behaving very sluggishly, a couple of seconds between pressing a key and the cursor moving on screen.
So I decided to turn off the receiver and unplug power. Waited a few seconds, plugged back, it initialized and was back to normal operation, including wifi.
My question is, has anyone here experienced this same issue? Should I be worried? It seems to me my receiver experienced some sort of partial system crash, perhaps a firmware bug, but perhaps it is something else?
