Digitizer problem even after replacement
I have 2 iPhones 5C.
One is locked to a network and the other is unlocked.
The unlocked one doesn't have any cracks on the screen and the display properly shows everything, but it doesn't recognise touch.
So I've swaped the entire screens, from the fully working phone I took off the screen and the digitizer and places it on the faulty one. ( I assumed it probably was a cable problem or a faulty screen with digitizer) but even after the swap, the faulty phone doesn't recognise touch......
Could this be a motherboard error?
if so, is there anything that can be done to remove the problem?
i would appreciate some advice if anyone had a similar problem b4.
Thank you.
Update (05/13/2016)
there doesn't seem t be any damage on the connector docs
Is this a good question?

Unplug the battery from the phone with the touch screen issue. Keep a screen plugged in and hold power button for 5 seconds. After you've done that, plug in the battery and turn on the phone again. See if that helps.
Does it not recognize touch at all? That means maybe water damage or damaged component chip near the digitizer connector on the logic board.

thank you for the advice, tried it..... it didn't work tho, it seems that it's a motherboard issue, but I'm wondering what could have possibly went wrong on the motherboard when I know there has been no water damage 100% , any advice as to what could I do next?
