Apple TV shows a black screen

I have an LG GX OLED TV connected to a Denon AVRS750H receiver through the eARC HDMI on the receiver. My son bought us an Apple TV 4K. I have it plugged in to power and the power light is on. I have a 4k HDMI cable connecting the Apple TV to one of the HDMI inputs on the back of the receiver. When I go to the LG dashboard on the tv one of the inputs shows up as Apple TV but when I click on that input I get a black screen, nothing is displayed, nothing happens.

I've looked at several YouTube videos and done several searches both here and on google but all of them assume that after plugging in power and cables you will automatically get a setup screen. But I see nothing. I really don't know where to go from here.

My TV and AVR will occassionally report "no signal" from the Apple TV 4K when switching to its HDMI port - normally a couple taps on the Apple TV Remote ("Menu" or "<" button) will light up the screen - I assume you've played with the ATV Remote this way?

The white LED on the front of the ATV4K device is on?

Assuming you can get video, go to Settings > Remotes and Devices > HOME THEATER: Control TVs and Receivers = On. Also verify that your Denon and LG are set for HDMI CEC turned on.

If you can't get video through the AVR with the ATV4K light on, plug it into an available port on the TV to verify it's not DOA (and to set the aforementioned Control option to On assuming it's not :-).

Best of luck.

That’s encouraging. It suggests that at least the remote got paired to the ATV4K, and that the Control TVs and Receivers ATV4K Setting I suggested you set is On by default. I assume that the Denon AVR also turned off/slept?

Since I’m good at making obvious suggestions… Have you powered down all components, I mean unplug them for a few minutes before trying again? Also, fancy AVRs can have their digital (HDMI) port labels changed about so they no longer match the actual labels on the back of the AVR - you’re positive that your Denon is set to the correct port for the ATV4K? When all is setup correctly the Denon should switch to the ATV’s port automatically when you wake the device but we’re obviously not there yet :-).

Well, you could test it by plugging the HDMI cable currently running between the TV and AVR into the ATV4K. That's a "known good" cable into the TV :-). If you see nothing then I would say bummer and contact Apple.

Yes, the white power LED is on and I’ve tried using the remote with no results, I have also plugged in the lightning cable to the remote and charged it.

The LG GX is the gallery model and is very close to the wall. In order to plug it directly into the TV I would have to pull it out from the wall and I didn’t install it, I paid someone to do that. So I’d rather not do that if it all possible. When you say go to settings I assume you were talking about the Apple TV settings? But like I say there is no video at all from it. It is a black screen.

thanks for the reply.

One more thing I just saw. I was playing around with everything again, using the remote, etc. Again only a black screen, then I decided to turn off the ATV by pressing and holding the remote power button. It turned off but so did my TV. So there is some kind of communication going on.
