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.
