Hi Jay
Is that you from e bay ?
Welcome .
Once the guys have given advise if we can not sort out the problem on here then pop round to mine one day this week and if it’s a faulty part we can swap out a few things if needs be .
One problem I do not have any LCD screens in stock but we can test it independently to see if it’s working .
I suspect a loose connection if you have nor]t damaged the bike or left it in a damp place .
Cheers
Baz
