Do you see anything on the screen when it's powered on? I'm referring to the dancing Roku logo when you first power the Roku on. If you don't see that, then try it on a different TV/display. If there's still nothing, then yes it died but should be covered under warranty (one year in the US). If you see the dancing logo when connected to a different TV, then you have TV issues, not the Roku itself.
