After updating my Apple TV 4K (first generation) to TVOS 18.2, the setbox shuts off spontaneously sometime between 10-20 minutes even while streaming content from any number of platforms. Can't figure out the reason.
Apple TV 4K (2nd generation)
Knowing that the TV was shutting down, which caused the ATV to shut down, lead me find that the sound bar I had connected to the TV was going to sleep after 20 minutes due to inactivity (I was using headphones through the ATV), causing the TV and the ATV to shut down. I went into my sound bar app and reset the sleep mode time to NEVER, and now my problem seems to have been resolved - no more ATV shutdowns while using headphones. Many thanks to all, especially philwupdx.
Interesting how I went from blaming hardware, then 18.2, then my TV, ultimately to discover the sound bar issue. The value of the community is huge.
I have an Apple TV 4K (3rd generation) new out of the box and also experience random shutdowns. Installed with TVOS 18.2 as well. Just checking to see if anyone has any software/settings ideas before I contact Apple Support.
Update - issue is much more prevalent when bluetooth headphone are connected to ATV. I went into my TV settings and unpaired all bluetooth headphones from the TV in case they were creating some sort of conflict, with no change in results. Next step, unless I get any suggestions here, is to call Apple Support before doing a factory reset.
another additional update - just got my replacement ATV 4K (3rd Gen) and set it up. It came with TVos 17.2 installed and I am not going to update it until after 18.2 us updated. So far, so good, but I will update again if the problem re-appears with 17.2.
The unexpected shutdown issue continues with new device and tvOS 17.2, so I know is not the OS or the hardware. Also, it is only happening when I have my bluetooth headphones connected to the ATV. I believe I somehow have a software/setting conflict somewhere in my ATV. I suppose it could also be with a setting in my TV, but with headphones connected to my ATV I am really only using my TV for picture. I'll do some more experimenting and report back.
Any ideas out there? While my symptoms seem more specific than others (ie happens while connected to bluetooth headphones), it believe the reasons for the shutdowns should be similar.
small update. this problem seems to only happen when I am sending a 4k signal. i just connected to a 1080p tv and the problem has gone away completely. This makes me guess there is either some kind of overheating issue or an overload of memory or cpu of some sort (sorry im not that technical, just guessing)
UPDATE: The problem seems to be stemming from the 3rd gen apple TV remote (usb c). All my cables are good. It's very odd. I paired a 1st gen appletv 4k remote to the apple tv 3rd gen and the problem completely went away. I also used a 1st gen appletv and connected the 3rd gen remote and the problem started happening to the 1st gen atv 4k. Anyone have any thoughts?
Update: I opened my ATV box and have replaced thermal paste. Previously, ATV would shut off within a hour but now it is running continuously for 2 hours. Fingers crossed!
My easing repeatable issue for this is when anyone FaceTimes me at all.
How were you able to unpair the remote?
