Hiboy S2 Lite Dashboard

The Hiboy S2R electric scooter dashboard did not fix the problem on my grandson’s scooter.
My grandson has ADHD & Is autistic & really loves his Hiboy S2R electric scooter. We have tried everything & it still will not work. He has had it at a shop for the last 5-6 weeks & Miss not seeing it in his bedroom every night.
Don’t know what else to do. Please help us.
Thank you

Didn’t last. Parts were recommended by the hiboy team, still didn’t work. And now I’m stuck with a hiboy that doesn’t work.
