After replacing a new digitizer, it now will not respond to touch!

Ok! I have an IPad 4th Gen Model A1458. I have replaced a broken digitizer in an iPad the prior responded to touch, but now after replacing it with a new one it now will not respond to touch! Now! Once I was removing the old glass, I inadvertently cut the digitizer ribbon to the old digitizer! This was the only thing that had occurred! Would this have caused a problem with the new digitizer such as a ground? Or is it possible the new digitizer just doesn't work?

Is this a good question?

Cutting your old cable would not impact the replacement digitizer or cause it to have touch issues. It is most likely that you received a faulty digitizer, which does happen often in this line of work. Since you cut the flex on the old one, it limits your ability to try your old one to make sure that it is part related and not an issue with the repair method (board damage etc).

Best bet? Grab another digitizer, maybe from a different source, and try again.

Make sure the connectors are pushed all the way in the White lines on the cable should be nearly entering the connector or disappear inside
