lenovo y50 screen compatibility

first of all the reason am asking all these questions is because am frustrated i av bought two screens and back case for my laptop due to the flaw lenovo made when creating the touch version of their y50 and now my screen is broken again due to the hinge issue of always popping out the back case.

pls i want to find out if the lenovo y50-70 touch and non-touch make use of the same model or type of hinge

also i want to know if i can change my lenovo y50-70 touch the screen and back case holding the screen to a lenovo y50-70 non-touch version

and i believe the lcd cables are different so if am changing i will need to buy a new lcd cable for a non touch version.

pls will the screen be compatible if i change it thats from a touch to a non-touch version
