Black screen (no backlight?) after LCD replacement.
I have replaced LCD in my iPad Mini 4 (A1538). Everything was ok for circa 30 min.
Suddenly, unit made some beepy noise and screen went black.
I was trying few different screens (including original one) but same symptoms: no picture.
iTunes is recognizig it after connecting, so I’m guessing that is backlight related issue (battery was disconnected during replacement).
I have found a lot of information how to fix such malfunction (replacing fuse, filter, making a jumper) but nothing directly related to that model. There is one movie on YouTube: https://www.youtube.com/watch?v=8ElCx1Ep... but mainboard of my unit has no visible damages, nothing is burned and all elements seems intact.
Can somebody guide me what should I do in such case? Post a picture with elements to check/replace?
I wan to buy: https://www.ebay.ie/itm/Ipad-Mini-Backli... as a spare parts.
I’m quite sure that I can do soldering myself, but I can’t find schematics for A1538.
Thank you in advance
