I’ve recently started to notice the top half of the picture from a 2015 HD Apple TV (not the latest 4K version) flickers every once in a while. It’s connected to a 4K TV via a Marantz AV8801 and it seems to flicker whether we are watching an Apple TV show, a movie or a Netflix show. Anyone else seeing this kind of problem?

Will give it a go. The problem is intermittent so it's hard to know if the cable swap is effective. I guess I will swap one cable and leave it for a few days. If I see one flicker, I'll swap the cables back and swap out another.
Going direct to the TV seems to eliminate the glitches and blackouts. That would seem to indicate it’s a problem with the Marantz unit. I guess it’s possible that using different HDMI cables might improve the situation. The ones I’m using are very high quality so I’m not confident it will fix the problem.
I have Chord HDMI cables so I’m pretty sure they are not the issue. Yeah, looks like the HDMI circuits on the pre-amp. I might move The Apple TV to another input to see if it’s just one input or all of them behaving the same way.
I moved the Apple TV to another HDMI input - I have 7 so lots to choose from :) No flickering or dropouts on the other input. So it looks like it might be a faulty HDMI input on the pre-amp. I guess I can live with one less input but I might contact the Marantz service dealer anyway to see what I can find out. Thanks for all the suggestions here.
Please check the hdmi cable , try another cable to see if that may be it.
I'll see if going direct to the TV improve the situation. It removes a cable and the AV unit from the mix. Thanks.
Yes, it sounds like the Marantz but to be sure test with another high quality HDMI cable.
