So if I understand this correctly, the three screens display fine but no touch on the old iPhone 5C. How do the three screens behave on the "new" iPhone 5C? Am I correct in understanding that they have the green stripe and no touch? In that case, I would say that both of your iPhone 5C's have logic board issues. The 5C logic board is prone to micro-fractures due to the inherently weaker plastic case. The board flexes more, due to "normal" falls and drops and causes these fractures. They are hard to see, requiring lot's of magnification. That makes these phones almost unrepairable.
