My 8 series 65” has started behaving very strange. When I go into the universal remote and set sources for my Sky box, PS4 and Chromecast then changing one of the input selection seems to change the input for all of my inputs.
Note: The reason I am using the universal remote is because I have a Sonos Playbar and need to join the home cinema device to the connection.
So for a clear example of the problem. I have this set-up:
sky box on hdmi 1
ps4 on hdmi 2
chromecast on hdmi 4
I go into the universal remote setup and select sources on one of these connections. I change it to the correct source. Doing so now changes all the sources for all 3 connections to that HDMI port.
I’ve done a factory reset but the same problem persists. Did some one break something with a firmware update?
