My touch does not work anymore

My mobile samsung j6 had fallen down from my bed to a distance of 2 metres. From then my touch is not working,

but there is no crack on the screen due to it.

It is working as perfectly as it can when I connect it to USB mouse or keyboard.

Is there any way I can retain my touch back without replacing a part?

(OR)

Is there any way I can retain my touch back by replacing a part and what part it can be and where can I get it?

(Even the smallest answer would be greatly helpful to me.)
