I have a Roku express model 3930x. It reset itself in the middle of a movie and is just sitting at the bouncing Roku screen. Power is from the wall and I am using the provided HDMI and USB cables. I tried a factory reset and it is still bouncing. I have power cycled, factory reset and hooked to a different TV. Please help. I am on vacation and planned on this device being a big part of my relaxation on the trip.
