HDMI-CEC is not working with Apple TV 4K

With my 4K Apple TV device HDMI plugged into my receiver, all CEC actions fail for all devices. I can plug in my older HD Apple TV and all is happy. Or removing the 4K device resolves the issue as well. I've just updated the 4K to tvOS 14 with same symptoms.

Anyone else experience this? I think the device itself has failed.

Cheers.

Apple TV 4K, tvOS 14

Amazon Prime not working on Apple TV I have an Apple TV model A2169 (64GB) and I have watched Amazon Prime for ever through the Amazon prime app. Now for the last 30 days I keep getting an error : Something went wrong, Please try again later. For more help, go to amazon.com/videohelp. The apps starts to play the video, then it pops up the error message. BUT the program is still playing in the background with sound but i can not get a picture. I have tried every Apple support suggestion. close the app and restart, close the app and power cycle the apple tv, delete the app and reinstall, set the tv back to factory settings. None of these are fixing the problem. What do I do?

Problem with PS5 Controller on 3rd gen 64GB Apple TV My PS5 controller acts erratically on 3rd Gen Apple TV 4K 64GB. Have tried 2 PS5 Controllers and also have the latest Apple Tv and PS5 updates. I also have a 3rd Gen Apple TV 4K 128GB and the controllers work fine. Also work fine on 2nd Gen 4K Apple Tv please release a patch to correct this issue. The controllers are unusable. Sometimes they work for a small period then start loosing the plot.

Apple TV 4K HDR issues on Samsung TV There are several older threads about this issue here, as well as a lengthy one on Reddit, but the solutions are varied, yet no one seems to be able to explain whether they originate from a software glitch on the Apple TV device or not. In brief: my Apple TV 4K has been working great for a few months with a Samsung 4K TV (a TU8000 model) until one day, the colors of everything on the Apple TV main screen and menus appeared greyed out/bluish/washed out. Unplugging the HDMI cable, changing the HDMI cable, changing the HDMI port on the TV, performing a reset of the Apple TV 4K, etc. - none of those worked. Disabling the HDR video format on the Apple TV 4K and enabling 4K SDR instead resulted in a mix of proper and incorrect colors - the menus looked good enough, but when streaming anything on any app (I tried Netflix, Paramount Plus, etc.), the greys and whites were incorrect, etc. What fixed the issue in my case was resetting the picture settings of my Samsung TV and then reenabling 4K HDR video format from the settings of the Apple TV 4K. My TV, by the way, supports HDR10+ and Dolby Vision. My question is: could someone from Apple explain why this keeps happening? There are older threads about this problem from 5-6 years ago, so this hasn't been fixed yet. And, while, in my case, it seems that there was some issue between the TV picture settings and the Apple TV 4K video format, this issue popped out of nowhere, without me changing anything on either the TV or the Apple TV 4K settings.

I've got a HDMI 2.0 cable and CEC has stopped working after the update. So shall I try HDMI 2.1 cable then?

Same issue and 4K is no longer an option for my 4K TV that was working just fine for years.

Didn’t make a difference (and I don’t see why it would).

Nov 7, 2020 10:09 PM in response to rmcewin

So, disabling AirPlay didn’t work here either.

Anyone else have any more ideas?

What is your TVOS version?

Nov 14, 2020 9:46 AM in response to rmcewin

I have the same issue.

Remote control is working fine with the TV and viceversa, but now I cannot power on my TV when I start my Apple TV 4K.

Ok.

Thanks for the steps...but how do you turn off CEC on Apple Tv?

Dec 20, 2020 1:53 PM in response to xseth

Definitely not for me. This is actually using Siri remote to put into sleep mode..

Same problems for me in July 2021. Spent 2 hours on phone with customer support and they couldn’t fix it. Come on Apple! Fix the problem… super disappointing
