No image on lcd after touch IC replacement
I have a customers iPhone 6 that had touch issues. The problem was not the screen but was on the motherboard. I changed touch IC U2402 and after process finish the lcd shows no image. ITunes recognize the phone, I can handle the phone through my pc, I can make a back up etch. But I don't know what I did wrong and I can't see the lcd image. Backlight coil is from the other side I don't think this is the problem. Can someone help me where to look on motherboard; thank you
Is this a good question?
