Hi, I just got my roku LE setup kit 2 days ago. I finally set it up last night and it worked fine. I went to use it today and the screen says roku in big lettering as it’s trying to connect then my screen goes black. What could be causing this? I had no issues setting it up until now when I actually try to watch something. I’ve taken my battery’s out of the remote. I’ve unplugged every cord to it and my tv and nothing has helped it.
