Replacement LCD touchpad not working?

Could someone whose done this provide some insight? Can't tell if the new touchpad I put in is defective, or if the damn cables aren't connected. The LCD output when turned on looks fine. Everything seems to be working, but I can't slide the bar. The damn cable 1 doesn't click in, and gives a flat bright screen on some attempts to get it in, so I might still not have it in correctly. Could another cable not be connected right? I can't tell if I should just send it back or keep tinkering.

It is not necessary to have such fragile material in this damn thing that it can't survive a small drop. Why make a face that will shatter that easily unless you want to screw your customers?

 

wait a minute

Ok, so the LCD doesn't do the input. That's the digitizer, apparently. Maybe that's why its called the "digitizer"? The damn cable 1 is to the LCD, and so long as its in, that works. Maybe I damaged the digitizer, or the glass isn't sitting on it properly? Maybe I just need to buy a glass and digitizer assembly?
