Hey there, you need to give more specific informations. What does mean that "screen is not allowing me to touch it", does it mean the touch isnt working but display works (show image) or display doesnt work at all?[br]
About posible problems, there may be few atleast:
# Display is damaged, sometimes happends even to new elements.
# One of the display connectors is damaged.
# Display works but touch doesnt work, in that case you need to replace digitizer on display, if you doesnt know how to do it this part my be tricky.
