Touch digitizer stopped responding.
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.
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?
