My husband and I recently purchase the Roku SE as a gift for our child. When she tries to turn something on, watches something, or even if the tv is just on, it constantly shuts itself off and back on. It doesn't go to the home screen, it shuts completely off and then boots back up. We have checked to make sure the cables are connected all the way. It has even done it when I've tried to put something on for her so it isn't something she's doing. What can we do for this?
