Touch stops working sometimes after screen replacement

Hi

This sort of behaviour can happen after a had aftermarket screen has been installed

To confirm this I would reattach the old screen and see if the behaviour continues

If the behaviour continues I would start to have a look at the LCD and touchscreen connectors and clean them with some isopropyl alcohol

After that it is a board level issue so if you haven’t done this sort of work before I recommend taking it to a authorised repair shop that specialises is that sort of repair

Hopefully this helps

Any questions please ask

Thanks:-)
