Apple TV 4K Random HDMI Signal Loss

I appreciate the help and advice. I got a new tv within a few days of getting the 4K Apple TV, so I don’t know whether the tv, the HDMI, or the Apple TV is the problem (the same HDMI cable was connected to the previous gen Apple TV and I never had any issues, and I didn’t notice a problem with the Apple TV 4K before upgrading to a 4K set, but it had only been a day or two before I switched) and am trying to save myself a lot of troubleshooting time.

At least now I know that replacing the Apple TV won’t solve the problem...

Thanks for sharing your experience with that cable. I know one other person in this thread also said using this cable fixed their issue. This cable looks like its in stock oil January 11th at Amazon. So I'll give it a try and report back. I'm really hoping this is actually a cable issue and not some other underlying issue with either the TV or the ATV4K.

Do you think running it through a sound bar woild still give me problems even if both cables I’m using are the echo gear? Or should I just hook the sound bar up directly to the TV and no bother with hdmi pass through?

OK, so after a few weeks with the Echo Gear 2.1 HDMI cable, I am still getting the random single loss. It was fine for a few weeks with NO single loss at all. Than all of a sudden, today, multiple signal losses and have to reboot the ATV4K. This has to be an Apple TV 4K issue. I cant see how its the TV's issue here when the set is a brand new LG OLED 4K that is dolby vision capable. Not sure if it has something to do with the new Apple TVOS software that apple pushed out yesterday. But the cable was working fine until today. Its just so strange honestly. I have it set to Dolby Vision 4K 60Hz.

I called Apple, and they said its got to be the cable. But I'm dubious that this is a cable issue at this point. There is no other fix for this. I have had no other issues connecting anything else to the TV such as cable boxes Blue ray players ect. This only ever. happens when I'm using the ATV4K. So even WITH the new 2.1 HDMI cable I'm still; getting the signal loss. So who knows at this point. Apple sure does not seem to think its the ATV though. If anyone has any suggestions. I'm all ears.

Yes, I mention that to them. And I'm supposedly talking to "Apple TV" geniuses here apparently. They just keep directing me to that **** 30$ belkin cable. But I've read at least one person on here has been still having the issues with the Belkin cable.

I hate to be the bearer of bad news, but I thought the same thing after I bought the echo gear and was using it for a little over 3 weeks before... you guessed it, SINGAL LOSS. It does not happen nearly as often as it did with the regular cables, BUT it still happens. Why its intermittent is a mystery to me, but it still happens. And its super frustrating. And the apple "geniuses " have NO clue what or why not would happen, their only susggetion is to buy the 30$ Belkin cable.

Since I’m having this issue with both my AppleTV4K and my PS4Pro, I’m wondering if perhaps it’s my Denon AV Receiver? The issue happens primarily (always?) when the device is outputting Dolby Vision or HDR (which, in the case of the AppleTV4K, it’s always outputting In Dolby Vision). Does anyone else have a receiver in between their AppleTV4K and their TV?

Im not using a AV receiver, my ATV4K is plugged right into my TV using an echoer HDM 2.1 cable. And it only happens when im outputting DolbyVision or HDR. Never had a problem with this same TV with the older non 4K ATV. So in my mind, this has to be an ATV4K issue with how it is outputting the signal to the TV (maybe?) im no expert of course but it just does not seem like one Televisions are these here.

What model TV are you using? And I certainly dont want to be the bearer of bad news, but I thought the same thing when I got the Echoer cable. Worked great for a few weeks, no signal loss. and then BAM. single loss again even when using the Echoer. So, your problem is fixed, for now. But is sure to return. Unfortunately.

My LG OLED is Dolby Vision compatible, its one of the main selling points of the TV. its an LG OLED B7. So While I agree with everything you say, its certainly accurate, I still am not convinced this is a Television issue, as I dont have this issue with other HDR or 4K content from other non ATV devices. Even when I output HDR or just regular 4K (non Dolby Vision 4K) I get the single loss. **** Even when im outputting 1080P I get the signal loss. Although NOT as often. But just the fact that it happens makes me believe that this is not an issue with my TV. Non of my other devices has this issue, even my older gen non 4K ATV didnt have this issue. And when talking with Apple Techs about it, they dont ev ben mention \that your television set needs to be HDCP 2.2 they just say, but the 30$ Belkin cable.

Hello,

Just purchased an ATV 4K for my 2017 LG OLEDC7 two days ago. I have been experiencing signal loss issues multiple times a day and last night every few minutes since I switched over from non 4K ATV. The problem seems to be getting worse and I even tried the Belkin cable that was mentioned in the thread to no avail. Had to go back to old ATV just so I could watch a show in its entirety. Only way to reset the ATV when signal loss happens is to unplug the power as it becomes totally non responsive. hopefully there is a solution out there.

Hi AviatorG822,

When I experience this issue, I most often continue to hear audio although the video signal is lost. Given that audio also originates from the wifi connection, I doubt wifi is the issue. Also, other devices connected to wifi at the same time don't experience a drop.

Thanks for you reply and experience, but this has been mentioned in past posts, and it is not really a solution to an issue that shouldn't be happening. Most people bought the ATV4K for the sole purpose of using dolby vision. The fact that it drops the single randomly almost defeats the whole purpose of this device. As The Dolby Vision is the main selling point. So thank you, but if im going to turn off Dolby Vision I might as well just get rid of the ATV4K and go back to the old non 4K one. And Apples only solution to this issue is " Buy our 35$ HDMI cable" which people have done (me included) which die not even solve the issue.

The issue still persists even if you turn off Dolby Vision, even if your using HDR or other non DV 4K, as you will im sure, soon find out. Good Luck. We sure are getting no help from Apple on this issue.

Been there, done that. It’ll start again. Just give it time. This is an ATV4K issue and not an issue with our TV’s (most likely) Apple needs to fix it and every “fix” that people come on here wth almost always is a temp solution before they are back a few days or weeks later saying it didn’t work. Apple needs to address this issue.

I referred him to this thread as well as sending videos of the issue. All was passed on to senior engineers. Radio silence ever since. I’ve been bugging Apple since I purchased the ATV4K (which I bought right on launch). Took them months just to realise the issue wasn’t my ATV going to sleep automatically (even though I made it painfully clear it was a HDMI issue and sent them videos etc).

I’ve given up checking in with them - disappointing and lackluster support. Seems to be a trend of Apple lately - great hardware, buggy half-baked software and they expect us to just wait 6-12 months for the bugs to be cleared out (if at all).

That’s my whinge for today!
