Apple TV 4K Keeps Cutting Out - How Do I Fix This?

Just bought Apple TV 4K. My TV is a Sony Bravia 4K from 2015. They are connected via a 4K HDMI cable.

Very happy with the Apple Box, but for some reason it keeps cutting out. This happens randomly. The screen will go black for about a second, then carry on as normal. Sometimes it won't happen for a while. Sometimes it will happen every five minutes.

This happens on a couple of apps, like the iPlayer app and the Now TV app.

I've re-started the Apple Box and made sure it is up to date. I've re-started the router.

Any ideas? Please keep in mind that I am not technically minded!

Sorry, Egon. I don't quite understand.

Where do I change the tv screen mode? Are you saying that the tv screen mode has to match the format setting?

I’m quite sure it’s a software problem not a hardware as such, I tried my older Apple TV HD that had older software as it’s been in a drawer having a rest….worked fine. Updated the tvOS and now has the same problems of randomly cutting out.

Waiting for the next os iteration.

Disappointing that a software release comes with such a problem. Also could not connect AirPlay with iOS 14.6.

Hi,

No it’s not hardware, I don’t want to be cryptic but the moderators would flag and delete. It’s, for me anyway, a software fault, I had tried changing all the hardware components so the logical thing was the remainder, TVOS 14.6 or if you like XIV.VI,

initially i had the apple box format set to 4K Dolby and the tv screen mode was cinema (from a choice of cinema, game, natural etc) and it kept cutting out, i first chance the apple box format to 4K SDR, this solved the problem however i knew my tv had 4K Dolby so i was playing with the settings when i discovered the screen mode showed 4K Dolby (as well as cinema, game etc) when the apple box was connected and selected as the source, once i changed the source it did not show. I then changed the tv and the box to 4K Dolby and its all good.

If your output settings are set to 4:4:4, change them to 4:2:0 and see if that stabilizes your signal.
