Chuwi Hi 10 plus touch screen does not work after replacement

Hi,

I have changed twice the touch screen of my Chuwi Hi 10 plus (same reference as genuine) but both touch screen do not work!

Before replacing it, the broken touch screen worked, i could unlock the tablet or access play store making research etc by rotating the tablet.

I do not understant what 's going on !

Did i miss something ?

I hope you can help me, i wish i could fix it

Regards,
