When I first bought my TV (UE43MU6175) all the HDMI sources set up perfectly including my Amazon Fire Stick, which was scanned and recognised as such by the TV, worked with the universal remote and had a proper fire stick icon for the source.
I have had to take it out of the port once or twice when changing devices around, and although it used to recognise the fire stick, now it never does, so the universal remote never works and it just has the generic HDMI icon. I can’t set it up manually with the remote as Amazon is not listed as a manufacturer.
I’ve tried restarting, plugging it in and out if the HDMI port numerous times, as well as toggling Anynet / CEC on both the tv and fire stick, but it never seems to work any more.
Any ideas would be very welcome, thanks!
You need to turn on Anynet+(HDMI-CEC) mode. I switched mine off trying to resolve a sound issue. Just turned it back on and all is working again.
settings General, external, device manager. Then then select Anynet mode.
Had the same issue and having Gone through all the tips here, nothing worked
i then tried the HDMI-CEC off > reboot > on toggle from the Samsung TV settings (not the fire stick) and it worked! Can now control the fire stick again
the setting is under :-
Settings > General > External Device Manager > turn “Anynet+ HDMI-CEC” off and back on after a reboot (hold power button down for 5sec and wait for on light to go solid)
Unplug your Fire TV and wait 60 seconds. Press and hold the Left button, Menu button, and Back button at the same time. Hold them for 12 seconds. Release the buttons and wait 5 seconds.
