Hi My Apple TV 4K (64GB) arrived on December 16th. The set-up was easy and I was impressed with the new interface etc. A few days later I noticed some flickering on the left side of the screen whilst the screensaver was playing. At the time I thought it might be a corrupt stream and put the Apple TV to sleep. It worked fine until last night when the same problem occurred again... The Television works fine through the normal Android apps, so this is definitely an issue with the Apple TV. I spoke to Apple Support today and they asked that I re-set the Apple TV, which I have done, however, it remains to be seen if the issue comes back. To me it looks like a hardware problem as I have looked elsewhere for a similar issue, but haven't found anything yet. The problem can be viewed here... Set-up: Apple TV 4K 64GB Sony Bravia 55" 4K TV Apple HDMI cable Any thoughts will be appreciated.
