iPhone 7 display issue

dan berquist 04/07/2020

Hi, I have no display at all on my daughters iPhone 7. I have put a multimeter on the pins on the FPC connector for the display and 7 or 8 are beeping in continuity mode. Now I’m trying to learn electronics at the moment and I’m pretty sure there should be no beeping when I put the multimeter on the connector pins. I cannot read schematics yet but I did have a look and it’s part J4502 and assuming I’m reading the numbers of the pins the right way up I’m pretty sure it’s pins-1,5,7,13,15 and 17 on one side and just pin number 20 (LCM TO MANY BSYNC CONN) on the other side. I have no idea where to head next to repair this phone, could anybody please point me in the right direction it would be much appreciated. Thank you in advance and on a personal note to you all out there, please be safe from this Corona. I live on the Isle of Man in the UK, we have a population of 82000 and 144 confirmed cases. Stay safe everybody, good luck.
