You should check the 5v. Comms protocols don't affect the LCD switching on the controller, since it has to do that before they can communicate.
I'll check the voltage but the display does turn on. What happens is that I get an error 10 code nor any speed readings. the original display wouldn't even turn on at all. It failed after 6 months of use. So the new one does turn on but receives no speed feedback and has the error code.

Check the 5v. Tests and measurements tell you what's wrong.

The bike should work with throttle and level 1 pedal assist without the display connected if you bridge the red and blue wires.
I tried that but nothing happened so I am guessing it is an issue with the motor. They replaced a flat tire at a bike shop but I am not sure if they damaged the wiring.

There should be a connector on the cable about 10 inches from the motor. make sure that it's pushed all the way in, then a bit more. There's a line that shows how far in it has to go.

I tried pushing it in hard but I only hear like a click, not sure if I need to press it even harder with some pliers because it will not go all the way till the marker reaches the edge
