This post is about Nokia Lumia 520 touch screen not working problem solution. If the touch stops working on your phone it can render useless to you so I decided to make this post for those unfortunate people who are having this problem.
Touch panel in Nokia Lumia 520 is not very strong so if too much pressure is put on the phone it can damage the touch screen to the point of it not working at all. If that happens there is no proper way to repair it, you have to buy a new touch panel from the market and replace it with the old one.
If even that does not work then it is possible that your touch panel connector is damaged. The touch panel connector is soldered on the motherboard, change that as well. If by any chance you have damaged the prints of the touch panel I have marked all of its jumper ways in this diagram.
