Apple tv 4k - picture drops out, says no input detected...

Hello,

I purchased a 4k Apple tv to go with my new LGC7 set. In the three days I've owned the television, the Apple tv has lost signal / dropped out at least five times. In the middle of a show or movie, the screen goes black, and "no input detected" comes up on the LG screen. The Apple tv box remains lit up, and flashes in response to using the remote, but no signal goes to the television.

I do realize that there is a similar thread, but I saw no mention of the "no input detected" message, and wasn't sure if what I am experiencing is the same thing or not.

It seems that unplugging the HDMI cable from the apple tv and/or unplugging the apple tv and plugging it back it temporarily resolves the issue. I have reset the apple tv, and have also restored to factory setting and set it up a second time, ensuring the software is up to date.

I realize there are many factors at play here - the HDMI cable, the television, and the apple tv itself. I'm still learning the television, and the HDMI cable is fished down through the wall and up on the other side of the room - it will be quite a task to replace it if it comes to that, but can easily attach another cable to test in the meantime.

As I proceed through various steps of troubleshooting - testing other HDMI cables, checking the tv settings, etc. - I wanted to ask if anyone else has experienced a similar issue with the 4k Apple tv or could offer any advice that would be helpful. Has anyone else experienced this?

Thank you in advance for your time and help...it's greatly appreciated.
