In this model, the digitizer is an independent system. Unfortunately, it is led with quite long tapes with a non-grounded signal. During installation, remember that the tape circuits provided for earthing must be glued through the conductive layer in designated places. Otherwise, it causes uncontrolled short circuits to ground or the signal does not reach the motherboard at all. Another (indirect) reason is too strong bending of the connection tapes and, as a result, breaking the continuity or being trapped by the screen.
You'll have to unfold it again and check your work. Alternatively, you can use an experienced repair shop.
