Apple TV 4 hdmi source issues with Sony TV
Problems with Apple TV 4 and Sony lcd TVs (KDL-40w5100 and KDL-46XBR9).
Purchased Apple TV 4 and swapped out with Apple TV 3 for HDMI 2 and 4 respectively. On both TVs HDMI 1 is the Comcast Xfinity cable box. When I change source to Apple TV 4, it changes to Apple TV for a brief moment and automatically goes back to HDMI 1.
If I unplug HDMI 1 then Apple TV 4 has no problem displaying without issue (there are other inputs on both TVs such as PS3 and chrome cast and do not cause any conflict). When I plug in HDMI 1 and switch to cable box, changing source back to Apple TV displays for a moment and switches back to cable box.
I have tried reseting the Apple TV via the GUI menu, I have tried unplugging all HDMI connections from the TV as well as unplugging the power for 5+ minutes, then reconnecting the HDMIs first then the power cable for each device and still having the same problem (HDMI handshake reset + holding TV power button down). I have also tried the other HDMI inputs as well as different HDMI cables
The HDMIs that I have are not uni-directional, the Apple TV 3 that this is replacing did not have any problems what so ever on either TV. I have also tried Apple TV 4 in the living room on a Samsung TV with a Comcast box as the primary HDMI source and there were no problems there.
