Replaced touch screen

[AC Question]

I broke my touch screen the other day (LG L9 P760 ). It's still working but i want to replace it. So I bought a new one, but after replace it, it don't want to sens any touch. So I tried an other one, but still nothing. Then place back the original one (the broken) and everything working again. Both of the two touch screens that i tried was new, and one of them was an original LG Replacement part. So what now ?

Welcome to Android Central! I'd suggest bringing it to a repair shop, before something gets more seriously damaged--unless you or someone you know is really experienced or qualified in this kind of thing.
