Samsung TV suddenly won't recognize Apple TV connected through HDMI. Used to work fine, but now for that input it gives me the option of Samsung Screen Mirroring. Cables,WiFi, etc. all are good.

Having the same issues, get a no source message on Samsung tv. Have to unplug apple tv to fix. This is with the new 4K Apple TV.

Having the same issue on a Samsung un40j5200af. The Samsung is not reading the Apple TV all the time. Switching th HDMI port yields same result. Every other HDMI device works on the TV (PS 3, 4,etc..)

unplugging the Apple TV from power then back on, the TV will recognize it, but this is not a permanent fix It eventually reverts to no signal.

detecting Anynet device also does not work, it reads that it is an Apple TV, but fails.

The only two fixes that have worked for me are the unplugging and replugging and also rebooting the Apple TV using the remote. Hit tv and menu buttons simultaneously and hold til light on Apple TV comes back on. It’s highly annoying.

Hi. I'm not sure what you're doing but I've noticed the following. If I switch my older Samsung TV to a different HDMI input, then back to Apple TV 4 (still on, not sleeping), Apple TV does not send a picture until I click the Home button (TV icon) on the remote. I assume this is because it won't send any signal when the HDCP connection is broken. So, try clicking the Apple TV Home button if it's not sending a signal.

Did you ever sort out this issue? I have the same problem. Turn on TV and change source to the HDMI input with Apple TV and get a no sopurce signal. Unplug and re-plug Apple TV and it works. So irritating.

I have the EXACT same issue, recognizes Firestick and did recognize Apple TV (newest one) and now won't. 60 in tv mounted on the wall can't easily get behind. Have tried to unplug Apple TV and restart still nothing. Please help!

try connecting it to another hdmi port

Hi. Has the Samsung firmware been updated recently? Have you looked in the Samsung settings for an option that affects the third input?

Test on another TV

Try another cable and port

Test on another tv

Same issue. Did you find a way to fix? I was wondering if its related to HDMI-CEC not being enabled or potentially my HDMI cable.

Did you try another cable and port? If possible try on another tv

It actually works after I unplug and replug the atv power cord, so I’m pretty sure the issue is on the tv (samsung) side.

Interesting, I'll give that a try.

Have same issue did you get it fixed?
