please take a look at the video i`ve recorded for more acuracy of failure description. a foto or a video allways more tha thousand words.
i can post another video with CU boards at starting to see LED light secventioning.

Your video shows the red wrench screen with all parameter sections on (full circle). According to the manual, this indicates a fault that is located in the platform. The first step it prescribes isvto check the two connectors. The second step is to reseat both batteries. The last step is to contact Segway customer care.

Beyond the recommendations in the manual, I would also suggest checking the mat and the 4 buttons underneath to be sure none of them are stuck.
