Hi. I had flipped my 4 wheeler in a ditch and the speedometer(lcd display) cracked and got water in it. I cleaned it out and had it workin but i took it in to the shop to get other things fixed and to reseal the lcd and he left it outside for like 2 months so i guess it got messed up and i ordered a whole new lcd display and plugged it in and all i get is the back light with no readings at all not even a neutral or reverse light showed up. What could be wrong?

 

I think your grounding out somewhere on your connections to the LCD. When connecting my reverse light, I mounted it directlly to the frame and I lost my LCD.
