These capacitive touch screens are very sensitive; most likely you damaged it [more than you think] when you dropped it.
If your within the warranty period or purchased an extended warranty that includes replacing the screen when damaged, you should call tech support to get an RMA [return merchandise authorization] number to have a warranty repair done. If it is out of warranty, you will incur the repair costs- that is, labor and materials.
