I replaced the whole screen today and the touchscreen still isn’t working. Any ideas?
Make sure that your cable for the digitizer is connected completely. Disconnect the battery first, then disconnect and reconnect the cable for the digitizer.
This is the cable you should be looking at. Just checking, did you happen to test the screen before completely replacing it? We get some screwy screens all the time, depending on the distributor. Keep us posted and we can go further from there.
dear friend, why you replaced touch screen (whole display)?, where you replaced?… if the whole display part is working … i think you had worked on motherboard, the motherboard contains an ic for the function of touch screen. so check it too.. [if the parts (display) you already replaced good one, ] good luck my friend
