Roku 3 suddenly not responding to original remote control.
My Roku 3 (4200x) suddenly does not respond to the remote at all (unknown reason, tried new batteries). I tried my Roku 2 (2720x) remote, but it doesn't work either. I can see the Roku menu on the TV. Would a new remote work or could the Roku unit have failed? Also, do universal Roku remotes work?
