I have done resets, including factory reset, to try to get 2 icons (YouTubeTV & TLC) to work. I have unplugged Roku box, TV, Internet connection.
I tried to set up Roku box again. I am stuck in "Error 003 Can't update". The only choice is "Exit setup" which goes back to blank purple screen.
Other TVs and Roku boxes in house work.
Thanks for the post.
