Solved: HDCP Error After Updating Apple TV 4K to TVOS 18.4.1

I recently updated my Apple TV 4K to tvOS 18.4.1. After this, I received HDCP errors when trying to view content from steaming services (e.g., Disney , Amazon Prime, Crave).

These post outlines how I solved this problem.

Background and Context

I am using a TCL 55R635-CA, to which I have connected the Apple TV 4K and a Sonos Arc (with an attached Sonos Sub Mini).

When I updated my Apple TV 4K to tvOS 18.4.1, I received a prompt on my TCL 55R635-CA that I had to rename the Sonos Arc that is plugged into the TCL’s eARC HDMI port. I didn’t think anything of it and selected a new icon, but otherwise made no changes to the configuration of the TCL audio settings. I had never received this kind of prompt, before, when updated the Apple TV 4K.

YouTube content played without any errors. However, when I tried to steam content over Disney , Amazon Prime, or Crave I received HDCP errors. The error messages indicated that I might be trying to copy protected content (I was not doing this). Solutions proposed were to reseat HDMI cables to ensure a good connection, test different HDMI inputs to confirm they all worked, or replace the HDMI cable in case it had become damaged.

Failed Solutions

  1. I tried to reseat HDMI cables. This did not resolve the error messages I was receiving.
  2. I rebooted the Apple TV. This did not resolve the error messages I was receiving.
  3. I reset the Apple TV back to factory settings, and reinstalled streaming services. This did not resolve the error messages I was receiving.
  4. I pulled the plug — to fully depower — the Apple TV. This did not resolve the error messages I was receiving.
  5. I pressed the power button on the TCL remote, to turn off the television, and turned off the Apple TV. This did not resolve the error messages I was receiving.

Solution to Apple TV 4K HDCP Errors

My Apple TV 4K and Sonos Arc are plugged into a TCL 55R635-CA. When you turn off the television using the remote you do not actually turn off the television and, instead, just put the television into standby mode.

To resolve my HDCP errors when using my Apple TV 4K, I pulled the power plug for the television. I left the TCL 55R635-CA fully depowered for approximately 3 minutes. I then plugged the TV back in and turned it on.

Once the television turned back on, and switched over to the Apple TV 4K input, the errors had been resolved. The problem, the whole time, was with the TCL television and fully depowering the television resolve the HDCP errors.

After many months of hope and anticipation, I’m looking forward to finally ditching the (cruddy and privacy intrusive) OS that is built into my TV and enjoying my new Apple TV 4K (Gen 2)! I admit to being disappointed Apple hasn’t transformed the Apple TV into a ‘true’ gaming device, but c’est la vie.

Now the wait begins for the a new Apple Watch

All I want for Apple to release today is a new Apple TV or, failing that, an absolutely massive cut in price to their very, very, very, very, very old Apple TV 4K. But really I want them to announce a new one so that I can take advantage of the full raft of Apple One services on the biggest screen I have in my house!

The Value-Add of Apple TV

Jason Snell over at Six Colors recently asked the question, “Why does the Apple TV still exist?” In the course of answering the question, he noted that Apple TV lets consumers:

  1. Play some games;
  2. Use Homepods for a nice, if somewhat problematic, Atmos sound system;
  3. Use HomeKit on their TV;
  4. Use the…remote?1

He goes on to discuss some of the things that could make the Apple TV a bit better, including turning it into a kind of gaming system, make it better at doing HomeKit things, or maybe even something to do with WiFi. Key is that as Apple’s content has migrated to other platforms and AirPlay 2 has rolled out to manufacturers’ TVs there is less and less need to have an Apple TV to actually engage with Apple’s own content.

I think that Snell’s analysis misses out on a lot of the value add for Apple TV. It’s possible that some of the following items are a bit niche, but nevertheless I think are important to subsets of Apple customers.

  1. Privacy: Smart TVs have an incredibly bad rap. They can monitor what you’re doing nor are they guaranteed updates for a long-time. Sure, some are ok, but do I trust a TV company to protect my privacy or do I trust a company that has massively invested its brand credibility in privacy? For me, I choose Apple over TCL, Sony, LG, or the rest.
  2. Photo Screensavers: I use my Apple TV to display my photos, turning that big black box in my living room into a streaming photo frame. Whenever people are over they’re captivated to see my photos, and frankly I like watching photos go by and remind me of places I’ve been, people I’ve shared time with, and memories of past times. There’s nothing like it on any Smart TV on the market.
  3. Reliable Updates: As Apple develops new features they can integrate them with TV environments vis-a-vis the Apple TV, meaning they’re not reliant on TV manufacturers to develop and push out updates that enable features that Apple thinks are important. Moreover, it means that when a security vulnerability is identified, Apple can control pushing out updates and, thus, reduce the likelihood that their customers are exploited by nefarious parties. TV manufacturers just don’t have the same class of security teams as Apple does.
  4. Family Friendly: Look, it’s great that lots of TVs can stream Apple content and that you can throw your screen/content onto Smart TVs using AirPlay 2. But what about when not everyone has an iPhone on them, or you don’t want to let people onto the same wireless network that your TV is on? In those cases, an Apple TV means that people can find/show content, but avoid the aforementioned frustrations.
  5. HomeKit: I know that Snell mentioned this, but I really think that it cannot be emphasized enough. Apple TV—and especially an updated one that may support Thread—will further let people control their Internet of Things in their home. Assuming that Thread is included in the new Apple TV, that’ll also make the Apple TV yet another part of the local mesh network that is controlling all the other things in the home and that’s pretty great.
  6. Decent Profits: Apple TV has long been a premium product. While Apple won’t earn as much on the sale of an Apple TV as on an iPhone, they’ll earn a lot more than what is being made when someone buys a Sony, TCL, or LG TV.
  7. Brand Lock-in: Let’s face it, if you have a lot of Apple products you’re increasingly likely to keep buying Apple products. And providing an alternative to Google or TV manufacturers’ operating systems is just another way that Apple can keep its customers from wandering too far outside of their product line and being tempted by the products developed and sold by their competitors.

On the whole, I think that there continues to be a modest market for Apple TV. I’d bet that the biggest challenge for Apple is convincing those who have abandoned their Apple TVs to come back, and for those who are using their Smart TVs to pick up an Apple TV that offers a lot of similar uses as their existing TV operating systems. That’ll be a bit easier if there are cool new things associated with a new Apple TV—such as positioning it as a gaming platform with AAA gaming titles—but regardless there is value in the Apple TV. The challenge will be communicating that value to Apple’s current and potential customers but, given their track record, I’m confident that’s a challenge that Apple’s teams can rise to!

Update: Snell catalogues many of the above reasons to get an Apple TV–as well as some others–in a new post based on what his readers told him.


  1. I actually really like the remote, but recognize I’m in the minority. ↩︎

With Apple preparing to potentially update some products for next Tuesday, I’m really hoping that they end up announcing a refreshed AppleTV!

While all the attention for tomorrow’s Apple event is, understandably, on the release of Apple Silicon (and the associated devices running it) I really, really wish that the company will announce either its long-rumoured new headphones or the refreshed Apple TV.
