During a competition this past weekend, one of our teams experienced an issue with the V5 brain screen. Twice in practice and once during a match, the screen turned all white and disconnected from the controllers. We were unable to drive and needed to unplug the battery in order to reset the system as the back button on the brain was not functioning. However, the battery LED still lit up when the button on the brain was pressed. We noticed that twice the issue occurred after the robot made minor contact with the field and the first time was seemingly a random occurrence. We want to know if this issue has been seen before and if there is anyway to prevent this in the future. The brain was running the latest firmware and pros code. Thanks!
