Apple 4K TV Black Screen Audio Only in Netflix

Saw a message this morning when ATV wasn't outputting video in netflix saying my HDMI cable doesn't support HDCP, which obviously it does. Rebooted and everything went back to normal.

Somehow the ATV4K loses its ability to output HDCP content after some period of time. I'm sure a bug like that should be resolvable if acknowledged and worked on.

This is what worked for me!

After months of playing around trying to resolve this issue, I finally figured it out.

Go to System > Settings > Reset (or reset and update)

This will reset the Apple TV back to factory settings, you may lose all your apps.

Set up the Apple TV from scratch following the prompts.

My Apple TV said that it needed to automatically change settings on my TV.

I clicked YES and it configured the TV and Apple TV to the correct settings.

Now Netflix works perfectly. No more black screen with audio.

If this works for you please let me know, I want to know if it works for others too.

Good Luck!!

I had the same problem after installing a 4K ATV.

After many resets of both TV & ATV, I have a solution that worked for me permanently.

Under TV video settings there was an option for HDMI settings which was set to Auto. I changed this to video and magically Netflix video content is now displayed.

I hope this helps you.

The issue appears to have been fixed in the latest tvOS beta. I have a Sony X800D and after updating my Apple TV 4K to tvOS 11.4.1 the issue completely disappeared. I'm going 7 days straight with no black screens or any other problems. Its been running fine this whole week. I have the auto sleep timer set to 30 minutes and it sleeps and wakes up fine. I highly recommend everyone having problems to update to the tvOS 11.4.1 Beta and see if it solves their issue. I will report back if the problem returns but so far mines running great!

Exact same issue here with a Samsung 4K tv. Seems to have started recently (aka last update).

Right now the fix I have is to switch to a different source and back to the Apple TV source. This seems to force the tv back to the correct resolution.

I switched off the new video settings in the Apple TV (her & framerste) but thus doesn’t fix the problem (but does lessen it).

I’m glad to hear this could be a bug and not a problem that requires a repair...

I had the same problem. Thought it was a Netflix problem so I watched it directly from my TV (2017 LG 65" OLED). Still didn't work the next day found this forum. I tried just doing the restart under settings and now things seem to be working again.

Well, a found a work around that worked for me. I ran my ATV through my Marantz NR1508 and used it as a hub, then ran that to the A1E. It solved the black screen issue. When I hooked the ATV directly back to the A1E, the issue came right back so what ever the issue is between the ATV and a lot of televisions is not an issue with my Marantz. Since the Marantz has HDR10 and Dolby Vision pass through...., everything works great. Been running this about 4 months now, the issue is completed gone for me.

Hello all!

Had same problem with black screen.

Found solution!!! Is below.

In mu case it was black screen, with sound and actually apple tv was working just black screen.

Problem appeared after update of firmware on my android based tv.

Restart of tv and restart of apple tv was jot helping.

Changing of source display, and back to apple tv was also not helping.

Solution: enter tv settings. In my case point called: picture style, it was as personal setup after update of tv, and i just put standard, and black screen dissapeared.

Let me know if worked with you,

Hope my post will be helpful.

I'm on my third AppleTV 4K with these same issues. Even updating to tvOS 11.4 the issue still exists. Everything works fine until I turn off the TV and return later to watch again. Everything in Netflix works except when I play content the video is black and caption and audio are working fine. On Amazon Prime content simply does not load. On directTV NOW the content just stops with black video and if I back up one level everything works again.

The only way to fix this is a restart of the AppleTV after which everything works great until the next time I turn off the TV.

I had a case open with Apple, escalated to the highest level, where they barely acknowledged this was a know issue. I have dealt with this for 3 months now.

I'm using a brand new Sony Bravia 4K (930E).

Once I upgraded my HDMI cable my problems went away.

Having had the same issue, I bought a more expensive HDMI cable. Problem solved. No hiccups whatsoever. It appears that not al HDMI cables are the same.

i turned off sleep and i have not lost video in a few weeks. that does seem to be the issue.

Chances are the HDMI cable doesn’t support 60Hz. Try changing to 4k HDR 30Hz on the video formats of the ATV settings

I have the Sony A1E OLED and 64 gb Apple TV 4k (Stunning picture quality I must say). I had the same problem when the Apple TV was plugged into any HDMI port directly on the TV but I did find what appears to be a permenant solution.

I purchased a 4K Marantz AVR (NR1508), ran the Apple TV through that, then ran the Marantz to the TV via ARC, and whala, that problem disappeared. Going on close to a month now no issues. The Marantz allows 4k and Dolby Vision pass-through and has the added benefit of directly decoding the audio.

Check again. I also noticed the issue is not presenting with the update. But if you look carefully you’ll notice it’s because the AppleTV no longer goes to sleep. This issue happens when the AppleTV goes to sleep. Until they figure out the real problem they just keep the unit awake.

It’s a good work around but don’t mistake this as a fix.
