Hello everybody, I am new here and don't have much experience with circuits and I have a problem with my bike computer. The display not show the number properly is this can be repair? Magene c406

 

Look for cracks, scratches, or water damage. Also check the battery voltage.

 

I think it's water damage is this can fix or i need to buy new one? What do you think the number on the screen is intermittent or the number the line is not complete

 

If the display is an LCD type, water can corrode the connection between the glass display and the circuit board. It may be possible to separate that and clean it and then it could work. OR not work at all.
