I did an update last week to 3.10.0 and since then my Atom seems to want to randomly turn itself off for what looks like no reason. I was watching a film on Netflix this afternoon through an Apple TV 4K and noticed random silence when the Atom just turned itself off. Never had this issue prior to installing the last update, TV is an LG C1 OLED connected with optical for audio, the Apple TV uses a Chord HDMI cable not optical and since having just the TV on using optical it hasn’t turned off.
Any idea’s?, I saw a thread on here from a while back but the comments have been turned off and the thread closed. Not sure if the update is just coincidental or if there’s an HDMI protocol issue.
Check you don’t have any loose speaker connections - caused issues for me once.
If the HDMI is to the LG not via HDMI ARC to the Atom I think an HDMI issue is unlikely, and equally can’t see optical from TV to Atom would be problematic.
Hold the Atom power button for several secs and unplug it from the mains and restart it to see if that helps.
I don’t think AppleTV/HDMI/Optical are likely to be causing the shutdowns.
I’ve just updated to the latest firmware and my Atom turned itself off after playing a couple of songs. Very annoying. Will disconnected it from the mains for a while and see what happens.
