Apple TV 4K Random HDMI Signal Loss

Hello,

I have the same issue with the same TV as you. When I unplug the HDMI on the Apple TV 4k and plug it again, it works for short time. This is a very annoying issue 😟

My Apple Tv4k just lost signal three times in ten minutes. I’m giving the Echogear HDMI a try...

I've been connected via Ethernet since day 1. Definitely has nothing to do with WiFi. My guess it's a fault in the HDMI handshake process between the Apple TV and TV. tvOS software issue I assume.

Worked ok with the Costco cable for a few weeks then the problem cropped back up. Now back to the Echogear and everything is working so far.

I am thinking this is an HDCP handshake issue with the TV and the devices. Since LG is taking a very long time to release a new firmware update to the US, I am hoping this will be fixed, soon.

Not an Apple issue, although it happens with the Apple TV.

I have the same issue with the Xbox One S.

I think the issue rests with LG, especially when you look at all reports about this issue.

I have the same issue with an Apple TV4, which makes me think it is a coding problem, also it seems to have gotten worse since last tvOS update. It is connected to an acer Beamer.

Same issue. I have a LG 65SJ8500 65-Inch 4K TV. The signal from my ATV 4K to the TV drops out randomly several times each day. To get the picture back, I have to put the ATV to sleep and then turn it back on. I tried all new cables. I tried factory reset. I have wired ethernet connection. Apple TV 4K signal loss is very frustrating.

Thanks Jason for your awesome comentson TV4k- I am afraid that I would go through the same problem.

So I can see here that I need to upgrade to 4kitune? I had tried whole morning to buy the TV4k but my hard

luck. I could not get customer service help for the feedback on phone..they seemed very busy. Your coments

have answered my question.

Thank you so much.

Follow up - I took my unit in and got it replaced. However I am now starting to see the same problems again. I did replace the cable and had it running to the TV with a 6' HDMI cable and had no issues. I have now reinstalled everything and am using a 15' cable - same brand. I'm not sure if the units are ultra sensitive to cable lengths?

Same issue here. Mine is an older LG 1080p TV. Sitting there watching something and then the picture judders briefly, then TV goes to ‘No Signal’. For me, the picture comes back after a few seconds, but I have to rewind the content. Very annoying. LG seems to be the common theme here (as well as th ATV4K of course).

Great find! I am actually using the Apple recommended Belkin Cable for the Apple TV found here and I am experiencing HDMI signal loss with this cable:

Belkin Ultra High Speed 4K HDMI Cable (2m) - Apple

It appears the Echo Gear cable is currently out of stock on Amazon but I'm encouraged that this is the fix. Would be interested to hear if anyone else has found another cable that might be in stock that works?

I too am suffering from this issue, glad I found this forum and it's not just me. I am using an Apple TV 4K, AmazonBasics High-Speed HDMI Cable, 10 Feet, 18gbps, LG OLED OLED65B7P with the latest update 4.70.36 WebOS. Even after the WebOS update last night I experience the blackout twice this morning, hoping it won't happen again. Also, I notice the blackouts more often while using Sling TV, I also use DirectTV Now, Netflix and Amazon Prime, but I've only had it happen a few times in these. I will be keeping an eye out for the ECHOGEAR 4 ft Braided HDMI 2.1 cables, hoping my cables are the only issue now and this is the fix.

I have ATV 4K, LG C7 TV. Everything was working perfectly for about a month, but now I am experiencing same random HDMI signal loss issue. It tends to be intermittent, but I have noticed it happening more frequently this past week. It is very frustrating. I'm not convinced that it has to do with HDMI cables as it was running perfectly for past month using same cables (which are brand new: Amazon Basic). Perhaps it can be fixed with a software update?

Same issue with my LGC7. Spoke with Apple last night and they suggested it was a cable issue, but they offered to replace my Apple TV with a “remanufactured” replacement.

It is the opinion of the group that I will likely experience the same issues with a different Apple TV box? I don’t want to go through the time and frustration if the problem will likely persist...
