This is repeatable.
Odd one… Just for curiosity, I cycled through the display by pushing the button… my intent was to keep the display on all the time… I like peeking at it once in a while and it is black most of the time.
Push the display button… push again and cycle through the inputs (started in USB), it cycles around back to USB (turning off on all inputs except USB and Auto… all OK here) then I hold the button in for a few seconds and start cycling through the other display items… When I hit “Max Volume High”, it stops there and is frozen. I can;'t turn the unit off by pressing the front blue button. I figured it would time out… it doesn’t. (UPDATE1: it timed out and went back to normal… I guess I didn’t wait long enough… not sure how long it was… screen came back to normal showing rate UPDATE2: Nope, still frozen after about 2 hours of use when I tried it all again.). I switched the unit off from behind… pulled the plug and it comes back up just fine.
The unit plays and sounds fine.
I noted a few times before here, the unit randomly went to 80 on the volume… another time I powered the unit down for a few hours and when I powered it back up, it came up with volume on 80. I never touch the volume… I control volume on my integrated amp.
Full disclosure: I live in an area where I have frequent power drops. I get maybe one email every two weeks from my NAS telling me my network is on battery power… logs show gap is only seconds but enough to trigger the NAS to send me an email. I do have the JR on a TrippLite power unit (no battery) that filters and adjusts voltage up or down for sags or whatever (I used to have frequent brown outs back when I lived in Center City Philly).
I also checked if my PrimaLuna remote may be being picked up the the JR… nope… cycled through the buttons and the JR ignores all.
Any tips? Heard about this one? I purchased the unit from on on Feb 7 2018 (this year).
