    You lose me at “little red button beside it that looks like an on/off button”.  But… I assume the Roku is powered up?  (Generally, you want it to be powered by a USB/AC adapter connected to the wall – sometimes a TV USB can work – but not always.)  Have you tried pressing buttons on the Roku remote?  Ie: try the Home key.  Some Rokus have a sleep/low power mode that does look a lot like “off”.

    You're right in thinking that the indications are that the Samsung recognizes a new device connected but powered down. I believe you should have an external power supply for that 3810X. Check that.
