I don't know if this is involved in your issue, but on a Roku TV you can set the input to be connected when the TV first powers up via:
Settings > System > Power > Power on
You can choose a specific input or have it return to whatever was the last input used.
Unless something has been added recently this doesn't give you the option to specify a specific startup channel.
