home button and touh id not working after screen replacement

i just did a screen replacement on a ipad mini 3. Now the home button and the touch id is not working. now, before the screen replacement, i did not test the touch id to see if its working, assume its working, also the home button was very hard to use, before the screen replacement, have to press very hard for the home button to work.

i re-seat all the cable, lcd and digitizer is ok, just the home button not working, upon startup, there is a pop-up that said something about touch id not available.

Anything i can do to fix it?

anyone experience this problem?
