I replaced the display on the phone, but black screen, no signs of life.
i ordered a new screen thinking its faulty, the screen is still black.
sadly i cant test the old original screen since the display is shatered.
phone boots up, my pc recongizes it. even its vibrating while calling it.
if its motherboard fault can someone point me in a direction where to look?

@robertomih87445 all of this "phone boots up, my pc recognizes it. even its vibrating while calling it." is what your phone should do if the display is not working. Did you make sure that you have the right display for your exact model. Have you tried a different vendor, just to rule out bad workmanship? After that you will need to get the schematic and boardview for your main board and try to perform some board level repair. Unless you have experience with that, it'll be difficult, but I would start at the display connector. Schematics etc. are available but I have not yet found any free copies. You'd be looking at something like this
While you work on your phone, take lots of pictures. Once you are done with it, take those pictures and create a guide for iFixit. That will help the next person that has the same problem as you do. It's easy and fun to create these guides. https://ifixit.com/Guide/new The iFixit community will appreciate this.

Hello, i have bought the same phone to test.
Both new displays are working, and after swaping parts i have found out that the main board is faulty.
The main thing needed from the main board are pictures.
I will try to find someone who could help me locally.
@robertomih87445 hope it'll work out for you and that you get your pictures back.
