Touch digitizer stopped responding.
Hello.
Posting this after perusing forum here and elsewhere.
Just finished opening and re-seating the touch screen cable.
iPad 4 wifi 16gb, zero history of abuse.
Never dropped and could go back in the original box as still looking new.
Touch screen quit working.
Resetting it did not work.
Followed instructions and successfully removed the screen and LCD.
Carefully disconnected the screen and home button ribbon cables and re-seated
Same with LCD.
Reapplied all the 'black' tapes.
Was very very careful with the ribbon cables and fairly confident none were damaged.
After reassembling the touch screen is still not responding.
The home, power, volume buttons all seem to be functioning.
It boots up as a new device and starts the setup process but cannot proceed past the wifi because the 'next' button cannot be used.
Question:
Is it possible the touch digitizer can quit responding without any damage or shock to the screen?
Are there any procedures either DIY or by Apple to determine if the motherboard is faulty?
I read several posts from others in a similar dilemma, having already replaced the screen without any success.
The replacement screen is not expensive but I wanted to first try re-seating the ribbon cable and unfortunately that did not correct the problem.
I already bought the precut adhesives and tools from iFixit.
Slim odds of replacement screen solving this?
Is this a good question?

Thank you for the replies.
The tip on making sure to tuck in the digitizer cable is very helpful and folks mention this out there on the web.
Unfortunately I may have missed out on the opportunity to try the "reseating the digitizer connection" by learning this detail after the fact.
The ribbon was crush folded with a clean crease which I unfolded and attempted reseat the screen with the ribbon tucked in properly.
Not sure if the ribbon cable can handle a fold.
As for the answer to my first question, yes, of course 'anything is possible'.
I thought an Apple Store could run a diagnostics to check the logic board and/or digitizer but nearest one is three hours away.
Still well within the DIY time/cost limit on this and will go ahead give it a shot with a new screen.

Thanks again.

If I may sneak in a somewhat related question about the wifi antenna.
Plenty of warnings about the wifi antenna ribbon cable during screen removal.
I believe I did not damage it and during test bootup the wifi setup page that comes up first lists our home network.
I am not certain if the functioning of the antenna goes beyond detecting and receiving a wifi signal.
Thanks again!
