I have relocated my Roku2 to a different WiFi. The ROKU opening screen appears, but there is no prompting for language or WiFi signals that are available. Non of the functions on the remote make any change to the screen. About every 10 seconds the screen goes black, and then the ROKU opening screen appears. I'm ready to give up. I thought I would give this community a try. Any help is appreciated.
By opening screen, do you mean the screen that shows dancing letters or some other cute graphics? It sounds like it could be a power problem. The last device called a Roku 2 is pretty old (and there were a few of them). It could be the device or its power supply have just given up the ghost. It may not be worth the effort or cost to fix it.
