2nd screen, lights up, no touch screen working.
This is my second screen from ifixit. Original broke during removal, was already cracked. Broke home button cable during removal. Did not reinstall. This screen just came in today, touch is not working on it either. Cannot input PIN code to unlock phone. Cannot verify with original screen to make sure phone is not issue. Everything worked prior to taking apart to replace battery.

@psycoduncan Grab some isopropyl alcohol on a cotton bud and rub the screen connector to clean off any possible corrosion.
Then plug in the screen but do not install it in the chassis. Try to boot the phone, being careful to keep any metal tools away from the phone as the motherboard is exposed. Does touch work?

@dannish tried and still not working.

@psycoduncan So you've tried two replacement screens and the touch doesn't work for both, correct?
由 Dany 完成的
@dannish yes, that is correct.
