Apple TV input not recognized

My TV, a Sony Bravia, will not allow me to select the HDMI input for the Apple TV 4 and stay on that input if there are other sources available. I've tried this with CEC turned on with the ATV where waking the ATV should automatically change the source to the ATV. It changes for 2 seconds and then reverts back to my satellite box. I manually change the input using my TV remote, same thing happens. It stays on a black screen that says HDMI 2 (Apple TV) at the top for 2 seconds, then goes back to the HDMI 1 Satellite input. So, I turned CEC off on the ATV, thinking that would fix it, as I've read others on here having issues with it working properly. That still didn't fix it. The only way I can use the Apple TV is to turn off all other sources attached to the TV (satellite and blu-ray player). This is only happening with my ATV 4. This didn't happen with the ATV 3 I had attached to this TV before.

As a side note, my blu-ray player's CEC integration with my TV is flawless. I put in a disc; the TV changes input to the BD player. I turn the BD player off, the TV goes back to satellite.
 
Be sure to wake Apple TV prior to switching input. "Menu"

Also, you could try your other HDMI inputs. Try switching ATV to blu-ray player's hdmi input, as a test.
 
The ATV is awake when I try this. I have also tried using the other HDMI inputs on the TV and other HDMI cables. Still doesn't work.

As dumb as this sounds, it seems like the TV sees the signal from the ATV as "too weak" and goes to the next available source for a better signal. Normally, if my blu-ray player were off and I were to go to that input, I would get the "no signal" message on that screen. It would stay on that screen about 10 seconds and then go back to the next available signal.

Good theory "too weak"...Did you try both ethernet and wifi? Have you ever gotten a setup screen? If not, then return/exhange.
 
Wi-fi and everything else works just fine. I can use the Apple TV, and I have been, but my TV will only recognize the input when all of the other inputs to my TV are turned off. It's not exactly prohibitive, but it is a big annoyance. I've talked to Apple support and gone through all of this with them, and they just say it's my TV's problem. I'd almost be willing to accept that, but this is the only device with which my TV has this kind of problem.

...(Sorry, didn't review your original post, for my follow up answer). That is frustrating to have to turn off all other inputs.

It maybe a problem with how your Bravia handles CEC. Try those different cable/input options with CEC disabled and then enabled on TV?.

That behavior would aggravate anyone.
 
I am having the same issue with a Panasonic TV and my ATV4. The work around they I have figured out is by manually swapping the HDMI with cable box and my ATV4 with them both on. I do not have this issue with my other Panasonic TV and ATV4.

Frustrating!
 
I tried something else this afternoon. I disconnected all of my other devices from the TV except for the ATV. I moved it to the HDMI 3 input. Normally, if I turn on my TV and it doesn't receive a signal from the last source selected, it will keep trying inputs until it receives a signal from one. I woke up the ATV and then turned on my TV with the expectation that since the sat. box normally in HDMI 1 wouldn't be available and now there was nothing in HDMI 2, the TV should switch to HDMI 3 and show the ATV.

Nope. Nothing. It just stayed on HDMI 1 reading "no signal." What gives?! What is the communication breakdown between the TV and ATV? Also, I did try the ATV 4 on another TV with the same results.

So whatever happened with this issue???
 
Nothing. My TV continues to ignore my ATV unless it's the only connected source that's on.

Do you know anybody else with a ATV4? Because I suppose its the device not sending enough "signal to the TV or or your TV(s) not seeing enough "signal" from the ATV4.

The only way to see is to try a different ATV4 on your setup...
 
I have the same problem. Known workaround is to turn CEC (aka Bravia-Sync) off on the telly, not aTV.
But that makes the whole CEC useless, a convenience I do not want to give up.
It must be something with aTV4, as no other CEC-device I have connected, behaves like that.
I can make aTV input stay, if I try to switch it several times, using several ways (via Input button on remote, recognised HDMI devices and defined HDMI inputs on home screen).
Really strange side effect to this - around 50% of times when HDMI input stays on aTV, I can control aTV with TV remote (meaning CEC works 100%) and the other 50% I can not.
