Suddenly my Apple TV stoped working , I changed hdmis , plug / unplug from tv to tv, restart with the remote, also menu & - volume...and is not working it seems like the tv is not receiving signal. So,I bought a new Apple TV , I connected and watched at night , then the next day same thing happened, no signal ..... not sure what is happening . I contacted Apple support they just walk me th the basic trouble shooting but not working ....Guys could you help me . I so desperate!!!

So what’s actually happening?
With my TV it powers on when I activate the ATV using the Menu button on the Siri remote, the TV however remains blank even though it’s on the correct HDMI input setting until I press the Menu button again.
Could that be the same issue for you?

tv does not detect the signal , I’m in the right hdmi input, just is not showing anything .... Apple TV is on. i use a monitor to check the same , and monitor says : input signal not found. It seems the ATV is not sending signal.

Probably stupid, but did you try one of the other HDMI inputs on the TV? Or another TV as well. Even most small sets have a HDMI input option.

yes, I tried different HDMIs inputs,cables and also different TVs . I cleanEd the ports too.

Seems weird it’s happened with two different ATVs, I’m wondering if it could possibly be your TV that’s caused damage to the ATV?

Yes I have thought that, but I do not understand TV to ATV communication. from ATV to TV is clear, send the signal ... how can the tv damage the ATV through a HMI cable ?.... I will receive a new ATV, but now I’m afraid that happened again... I use other devices in the same tv, such as Nintendo switch and blue ray...those are working perfectly

First I would check whether the Hdmi cable needs replacing - try it with your dvd or one you know is working from your dvd with the atv... cables are usually the first things to go wrong

i did that , see post above.cables, different TVs, different hdmi inputs .. but still same issue..

Looks like maybe samsung firmware - https://us.community.samsung.com/t5/HD-and-UHD-TVs/Apple-TV-won-t-detect/td-p/866682 This wouldn't explain why the TV then doesn't work when connected to other devices, unless they're maybe samsung also? Unless the TV is changing the settings on the TV first time round which it remembers & doesn't work with other devices, think there's a auto HDMI setting it video & audio in settings on TV if that turned off and set to manual.
Maybe try this - Hit tv and menu buttons simultaneously and hold til light on Apple TV comes back on.
& this from 2017 looks like similar topic https://discussions.apple.com/thread/7860380?page=2

Thanks McSobby... I found that and I did the factory setting to the tv, but still the same, also I did the reset to the Apple TV ( tv icon + menu) no change, not sure how the tv can affect the Apple TV, ....I have a HP monitor , i also connected there , but not working ...same issue .... my previous Apple TV was working perfectly for more than 2 years, then suddenly that happened ...

Just to be clear... your AppleTV light is on (solid green) but the screen is blank? If you have no picture, you can't use the AppleTV Remote or the app to control your AppleTV from your phone to reset the device... you need a picture to use the menus. I don't believe you can use the computer to reset the AppleTV 4K, but it's the only manual option that I know of.

If you have exhausted all of the above... consider the possibility that the device is defective. The fact that it worked then stopped working suggests the system board may be the culprit. Is it still under warranty?

Going into settings and see if "Input Signal Plus" is turned on for that particular HDMI input. Something I have to fix frequently in my custom install job. I believe it is under system and external device manager. I avoid Samsung like the plague because of how they won't play nice when it comes to UHD and other things....

I found my old Apple TV .... previous gen ,not even HD , I connected and works really good, today, I received the new Apple TV ( replacement )not sure if I want to connect to my tv.....

Sorry Jamie, not on this forum daily but yes the TV settings. Samsung has stuck to their own standards and ignored most of the new high resolution options. I can't say for sure but a simple setting being turned off can bring your Apple TV picture back. The first time I stumbled on this issue I spent about four hours troubleshooting before I found the issue. Now when I customer has no video output from a 4K Apple TV, I immediately check to see if the Samsung TV has somehow turned input signal plus back on....

Well, not sure if this is the problem , because when I plugged to other devices like an HP monitor happened the same, I can not see image/signal ... it seems strange , but not sure if the TV damages the Apple TV, but I will give a look.

Possible, but I've never heard of a single instance where this has happened.

I`ve had a similar issue multiple times and this has always fix the problem for the time being.

Thanks Mann, I will try...but the weird think here is if I connect to other devices I had same issue, I connected to a HP monitor and it says “not signal”. Not sure if there is a communication TV to ATV, and tv is damaging the ATV

GUESS WHAT.
