iPhone xr screen not working, replacement screen also black

So I picked up an iphone XR, and the screen wasn't working. When it turned on, only a faint white light showed and nothing else, but the phone was still working (vibrating, iTunes/3utools detects it).

So I bought a replacement screen, followed the ifixit tutorial, and reassembled the pieces onto the new screen (as far as I know exactly like it should've been), and connected the 3 flex cables to the phone and tested it before screwing everything back into place,

but the screen didn't turn on, and also didn't have any faint white light showing. But the phone was still working. I tried restoring it, hard reset but still nothing on the screen.

So then i replaced the parts from the replacement screen, and putted it on the old screen, but this time it was also completely black and not even the white light was showing.

So what could be the issue here? I guess it has to be a hardware problemen, but wich part? The screen itself or the earspeaker?

Thanks in advance!

If you shine a torch on the screen can you see an image? We need to know if it is an image problem or backlight problem. It will not be the ear speaker.

@imicrosoldering I just tried the old screen again, and there is a white glow again. With a torch I can't see anything, but if I were to guess I think that only the backlight works. Because if I turn it on and lift up the screen, I can see white light coming from the back of the display.

You have ruled out parts and backlight and confirmed it is an image problem. The next step would be making sure the display connector has no bent pins and the connector is seated properly than use a multimeter in diode mode and test the pins on the logic boards display connector. You will be looking for an open or shorted line. Once you have found the faulty line you can trace it back to the failed component. I would mention that to fix this issue will require microsoldering skills and equipment plus board view software.

From the looks of it, the problem are the pins on the logic board . Image :

@pj0tt3r It is fixable but you will need the right equipment and experience which would cost a lot more than having a reputable repairer to do the repair.
