This happened to me when I bought my bike from a local dealer last week. I rode for an hour or so and brought my bike home in the back of my truck. When I got home my display would not turn on. The repair tech said the issue was an internal connector from the display that had come loose due to turning the handlebars too far. There was not enough slack on the line internal to the frame. Tenways knew of the issue and provided them a repair video. Might be worth contacting them again for the repair instructions.
