Apple TV 4k, Netflix: Audio only, no Video. restored ATV to factory, reinstalled NF app, cable is compliant, AVR settings and TV settings ok as no issue in other apps. Worked fine until today. OS 11.1. everything has been reset, reinstalled, rebooted, and reconnected. Any ideas? NF works fine through the app on the TV as well as the app on the cable box.
Apple TV 4K, iOS 11, 11.1
I had the exact same problem with the Apple TV 4k (OS 11.1, most recent update)
TV: Hisense 55H9B2 4k curved tv
Cable: Apple-recommended Belkin Ultra HDMI cable
(plus about 6 other 18Gbps cables I bought from Monoprice for much less)
All YouTube 4k content played fine, and I could play 4k movies from iTunes with no problems. Netflix would allow me to browse the content, but when I played 4k videos I would hear sound and could see the UI elements but the video stream was a green screen. When I played regular 1080P content the screen was black, but I could hear sound and see UI.
The Apple TV 4k automatically chose 4k SDR, and would not switch to any other output resolutions. I called Netflix and Apple trying to troubleshoot, but neither could find a solution except to point out that it seems like an HDCP 2.2 issue and to try upgrading my cable. I tried 7 difference cables, including the recommended one from Belkin.
I finally found a post on Amazon for my TV which mentioned that my TV firmware needed an update. The TV's online firmware update feature returned nothing, but I knew mine was the oldest shipped for this TV. Thankfully, someone posted the most recent firmware file on Amazon. I updated via flash drive, and suddenly the Apple TV 4k asked to upgrade the display output to 4k 60Hz HDR. After I changed the output, Netflix started displaying all videos properly.
Check for a firmware update for your television.
For reference for anyone with the Hisense 55H9B2 TV, I upgraded from F1211 to H0117 in order to enable 4k 60Hz HDR (https://www.amazon.com/gp/customer-reviews/R24J42DVDCE5FM/ref=cm_cr_getr_d_rvw_t tl?ie=UTF8&ASIN=B00ZGIJDOU).
using apple tv 4k with LG 65UJ7700 65" 4K tv
I have the same issue where audio keeps coming though but screen is black. restart apple tv video comes back. have swapped out cables with Tripp Lite hdmi 4k cables as well as a belkin cable and problem persists.
I've tried disabling Dolby Vision & running on HDR and issue persists.
it has be something that can be fixed with an update.
have even moved my xbox one s to the port that had the apple tv4k attached to and had zero problems with the xbox.
this happens whether I'm using Netflix, Vudu, HBOGo, or Showtime Anytime.
apple tv is updated to most current version of apple tv os available today 2/6/18 and tv has most current version of LG software updates as well.
Is everyone doing a reset or a restore. RESET will not work.....RESTORE the Apple TV . This will completely delete everything on it and re install the latest iOS. This has to be done using iTunes, maybe this is why if people are only doing a reset nothing is getting resolved. RESTORE not RESET. Just Luke when an iPhone is restored in iTunes. Hope this clears up any confusion on what to do.
For now just turn off the auto sleep feature. I took mine in to Apple and they did a Restore which did fix the problem but I did know until I got home. Just in case I had them order a new Apple 4K tv as well which I did go ahead and get when it came in. I have had no issues with the new one or my original after the Restore. I can only guess the that one of the updates corrupted the firmware and required the Restore which reinstalls the latest iOS.
Someone on AVS forums mentioned to try switching to an input on the TV that doesn't use HDCP when turning the system off. So for me, I programmed my Harmony to switch my 930E to HDMI 1 (which is empty) when I turn the TV off. This seems to have "helped" a bit. I put that in air quotes because it certainly hasn't solved it......but for the past 2 days I have been able to turn on my system and have the ATV be fine. Although it has occurred at least once during the day, so like I said.....not a complete fix. Might be worth a shot for some. In the end I believe this is something Apple needs to address because I have yet to have this problem with my Roku Ultra.
I have a list at least as long as @felixkas with no luck yet....and my list does include turning off auto sleep.
I have also
- made sure the TV stays on the ATV input when turning off
- made sure the TV switches to a non HDCP port when turning off
- adjusted startup timings of devices in chain to give enough time
- I have no screensaver, no sleep on my ATV
Does anyone else notice that often when this happens, when you wake your system up (even if the ATV is set to never sleep), that the ATV interface has the first icon on the first row selected? It's almost as if somewhere during the time when the TV is off...Headboard (which I believe it what they call the tvOS Springboard) crashes.
Usually when I turn my TV off, I leave the cursor on the ATV on the 3rd or 4th item on the first row, yet when I wake things up, it's on the first item. I have no commands on my Harmony to do anything with the ATV during startup, so I'm assuming that something crashes. Wondering if that is contributing to this.
Here are my 2 situations:
1) ATV4K set to 4K SDR/HDR: I lose video in netflix after a few hours of not using the system. Doesn't matter if I let the ATV sleep or not. Only a reboot fixes it.
2) ATV4K set to 1080p SDR/HDR: I lose video in netflix after a few hours of not using the system IF I have auto sleep set to any number value. I DO NOT lose video ever in netflix if I disable the sleep function on ATV.
I’m still on iOS 11.3 with my auto sleep turned off and has been for quite sometime now and I have not had to do a restart. I have a 4K Sony Bravia TV. I have noticed that awhile back that when I tried to watch Netflix after watching something on AMC that I did have to do a reset. This has happened a couple of times to me which is different than what was happening to us all in the beginning. This whole issue has been quite a journey.
Well folks, I think they've fixed it!
Since day one of owning the Apple TV 4k I've had this issue of the video cutting out on my 65" Sony Bravia x900e.
I would have to reboot the ATV every day, sometimes twice a day if there was a long delay between using it.
I've installed the Beta tvOS 11.4.1 (15M5054b) and I haven't had to reboot in 4 days.
So happy, this is working now. Hopefully it doesn't break again when they add all the new features they just announced.
Its possible you went from tvOS 11.2.5 beta 1/2 to Beta 3 which just came out today. So even though the version # is the same, the build number should be different.
Did you do a factory reset on your Sony?
I have not done so yet. It is however updated to the latest firmware (November 2017). Whether it's related to the Sony firmware, I don't know. I will give it a factory reset when I have some time.
Try taking the Apple TV out of being able to go to sleep. That helped me as much as anything. If mine doesn’t work tonight Apple has my replacement Apple TV 4K to pickup.
Just turn off the Apple TV auto sleep. This is the only thing that seems to work without a restart.
I have the same issue with a new Sony 4K panel. Come on Apple fix this!!! I have less issues with my Roku. How about Youtube 4K while you are at it!
The 11.4.1 betas fixed the issue for me. Accidentally left autoupdate on and now I’m on 12 beta. The problem is back now. Anyone know of a way to downgrade?
