4k TV randomly loses HDMI signal

4k tv randomly stops playing, displays a black screen, then returns to show with it paused. Sometimes it states that there is no HDMI. All this since I updated to iOS 26 last night. I have replaced the HDMI, reset device, and all the other recommended actions.


This happened a couple of years ago and the fix was to alter the setting that allows the Apple TV to turn of the display TV…tried that also!


Can I roll back my iOS update??

Done, and done…swapped it with an Apple TV from another room that’s on the previous software release and it works perfectly. The fault followed the updated box when I put it on a different tv, DEFINITELY a bug with the new iOS release…it was working perfectly prior to the update.


Guess I’ll have to wait for the next update 🤷🏻‍♂️

No you can't roll back an update.
