It might be a damaged cable or connection, so find every one, disconnect, check, reconnect. There probably are not many, possibly just cable into motor, the battery mount and the cable to the display.

Remove the battery, check contacts, refit.

If display is removable, check for damp, dirt, any springy contacts working properly.

If not fixed, find where cables plug into motor and check those.

There are a lot of potential causes, so it can be difficult to find it. The easy ones to check are the pins on the back of the display. I had one where water got in to the holder and the corrosion stopped the pins from springing. The next easy thing to check are the connectors to the motor. After that, you're probably going to need to open the motor to see if water has got in.

a purion display will be less hassle or you could use a kiox display i have on my bike so you can use the app ect

As others have said, check the connections from the intuiva display to the mount. Especially with slightly older versions (including mine) that is quite prone to bad connections; a design issue in the mount. I believe they fixed that in later versions of the mount.

I seem to remember that the different mount versions had different arrangement of the colours of the contacts, but that may not be correct.
