Cadillac Cue replacement
 

My Cadillac Cue touch screen stopped responding to touch and was stuck on the home screen. After some online research it seems many others have had this issue and they bought a replacement screen and installed with success. I did this and after a couple hours popping out the center unit, taking it apart, putting new screen on and popping it back in I have the same exact issue. Is there maybe some other issue ? When I put my hand to the screen the options do not pop up, so maybe there is some other issue or perhaps my replacement is bad as well ? Anyone else have the same happen to them and if so, what are other options ?
