I got my replacement Apple TV. It's on TV OS 11.0 it works perfectly. The problem must have been with TV OS 11.1 & 11.2I just took advantage of the DirecTV Now promotion to get a free Apple TV 4K today. Upon setting up the device I immediately updated to tvOS 11.1.
After the update I noticed a major issue that's happened frequently throughout the day. I would start a stream on DirecTV Now and it will work fine for a few minutes until the screen goes completely black. There's no video at all except a black screen but audio plays just fine. The guide within the app works normally during this time. I would exit to the home screen and picture with all my apps would come back. So it may be app specific. Except that it happens to all my apps. When I go back to streaming content all it would show is a black screen. The only way to fix this is to restart the Apple TV and it would work fine again for a few hours.
This issue applies to all apps that stream video including Directv Now, Netflix, Hulu and Plex. Black screen but audio works. I'm able to scrub through the video such as fast forward and rewind. The UI still works fine but video stays black screen no matter what I do. I'm a bit lost and confused as to why this is happening. I never had this issue on my Apple TV 4 and I didn't notice this happening prior to updating to tvOS 11.1. Could it be that it's a bad update?
I'm about to perform a factory reset and hope for the best. Does anyone have a similar experience with their Apple TV 4K? Could it be an HDMI cable issue? Maybe it's the software? Any ideas? Thanks in advance!
For those wondering, video Format is set to 4K SDR YCbCr Chroma 4:2:0.
That's good to hear. At least that leaves us some hope that Apple can fix this in their next firmware update.I got my replacement Apple TV. It's on TV OS 11.0 it works perfectly. The problem must have been with TV OS 11.1 & 11.2
Has it ever been possible? I thought it is always been the same wih all iOS devices - once Apple closes the old firmware signing window, there is no going back, irrespective of the ports.It sucks we can't downgrade our Apple TV's this generation because they decided to leave out the USB-C Port.
Yes, Apple has always locked their firmware past its signing date. But if the firmware is still being signed it can still be downgraded.Has it ever been possible?

Or was it different with aTV??
What brand & model TV are you connecting the ATV4K to, also what HDMI port and rating on your TV?If you turn off your TV with the Apple TV input on it will do this. I notice if you turn off your TV when it is on a different input it does not occur.
I have found out that with HDMI issues pulling the plug is sometime the only solution. I have just done it now, and finally turning off the (Bravia) TV it turns off the ATV 4K as well. I hate the software of this TV! It's a complete mess.This bloody Android TV needs also restarting, more often than you might want to think.
On Sony you either hold the "power" button on remote down for 10 seconds or pull the plug.
I am not sure I am allowed to talk about it (NDA crap) but being in the Appleseed program I have opened a bug report. No answers yet, though.Anybody found any fixes yet? Have me made Apple aware? (assuming it's an apple issue as it used to work a few updates ago).
My all-Sony setup behaves exactly the same.On a slightly different matter, is it normal for the AVR (I have a Yamaha RX-v483) to take up to 10 seconds to run on after turning on the Apple TV 4K? The TV turns on immediately. Is it again something with the Bravia (like, I don't know, the AVR is off so the ATV 4K goes through standby HDMI passthrough, the TV turns on and then the TV via HDMI-CEC turns on the AVR). The "stop" from ATV 4K is immediate for all devices, though.
So after the last 11.2.5 beta update the AVR turned on immediately the few times I tested it (I did few tests because I noticed that change). Now it's a bit back to the usual, maybe it take a bit less time. Having 3 pieces involved (TV, AVR, ATV 4K) who knows what's going on..My all-Sony setup behaves exactly the same.
aTV will only report to connected TV that it wants to become "active source". TV+AVR will then figure out the correct signal routing and TV will wake AVR to apply it's part of routing, if needed. AVR will also negotiate with TV and become the default Audio device (Bravia will flash a banner about that event).
I can provide you with my CEC logs if you want to dig deeper into the protocol
Power-off from aTV is sent as broadcast, ie all devices on bus receive it at same time. Everyone will process it in own pace, naturally. For example UBP-X800 will take 30-60 seconds to wrap itself up and shut down.
PS Check the Supplement 1 CONSUMER ELECTRONICS CONTROL (CEC) on page 213 in the definitive document. It documents all required message flows.
I also have a bug report opened with Apple but have yet to hear anything on it. I have sent logs/sysdiagnose/console output to them.I am not sure I am allowed to talk about it (NDA crap) but being in the Appleseed program I have opened a bug report. No answers yet, though.
And today after the latest 11.2.5 update it still doesn't work (just tested it)...

This is interesting. So what you are saying is.....before turning off the TV, simply change the TV input to any other input, just not the one the ATV is on? I'll have to try this.Not leaving on the Apple TV input when turning off the TV seems to fix it. As long as I have it on another input when i turn the TV off it seems fine as I have not had to reboot it in days.
Yeah, it does sound like an HDCP error between the ATV and the TV after a period of idle time. @tonyr6 had an interesting approach of making sure the TV switches to a different input before powering off. Guessing the point in this is to make sure the next time the TV is turned on, you have to change the input to the ATV input, thus forcing that handshake again. I've managed to program this into my Harmony.....so we'll see if that works.A black screen with working audio sounds like a bug in the HDCP authentication:
It's a hardware issue... which is why Apple Store will suggest a new cord.
This is same reason why you can't take an Apple TV, plug it's HDMI-out into your computer via a 4K capture card (like for video game streaming)........ if you try to "record" Netflix content, you'll get a black screen with full audio...... somehow it "knows" you're plugged into non authenticated device, and blocks the video.
In 11.3 beta the ATV 4K randomly turns off when turning off the TV. It worked a couple of times that I tested it. It didn't another couple of times. Well, it isn't vital.I also have a bug report opened with Apple but have yet to hear anything on it. I have sent logs/sysdiagnose/console output to them..
