I connect my Roku box with HDMI to my HDTV. Frequently when I switch to the Video for the Roku HDMI I get a solid blue screen. The Roku remote makes the box do the usually sounds when I click on home screen but nothing happens. Sometimes I disconnect the power to the Roku and reconnect and get the home screen but often the solid blue screen returns. Sometimes the home screen appears after 5-10 minutes but often I just give up. Once I get the home screen everything works fine.
Any thought why I have a solid blue screen and what to do about it?
