Hi can’t seem to find much information on the ipad pro repairs? swapped a screen on ipad pro 12.9 (2nd ipad pro 1st no probs. followed all of the usual steps and took great care in my workshop as usual however I now have no power and no response when plugged into iTunes. i have tried to disconnect battery for 30 mins or so. checked all soldering and connections second part still nothing. can’t find schematics or any info anywhere. customer device :( thanks in advance.
if the screen is not an apple product then it may act up. (they did this on purpose to boost there sells).
