iphone 6 homebutton touch ID not working

After replacing the screen, homebutton touch ID doesnt work.

There is no damage on the board.



- Have replaced the homebutton with a new touch ID

- Have replaced the homebutton extention cable to the logicboard.



Homebutton click function works fine!

But when i turn on Touch ID, it keeps saying

Touch ID failed...



Its like the phone can not detect the Touch ID at all...



Any solution?
