Can you fix the problem with the "Help" button? If so, try increasing the inter-device delay. If not, then it's an input configuration problem. I checked your TV (Samsung HP-S4273) device and by default, its Adjust Inputs is configured to use the direct method (I go directly...). The Input labelled "TV" uses the command "InputAntenna". Recheck that. Check that this command (InputAntenna) works properly in device mode. Check that the TV input, in the "Watch TV" activity" is set to "TV".
