Check the pins for damage, on both the board and the cable. You may also want to test the LCD on another unit to see if it's functioning properly, but of course, check the cables before applying.

I have a OEM iPhone 8 Plus LCD pulled from working device.. Won't touch.. But if i put a 7 Plus LCD it will touch?

If the 8 plus lcd isn't working with the 8 plus I would just encourage testing another screen if you have one available. I've actually never seen/heard of this issue occurring. Most people say the display will show but the digitizer will not function unless connected with the proper screen.

The only option I would have left is to install the Iphone 8 plus LCD and run a restore on the device to help reset the partition.

Let me know how it turns out.

Thanks for the ideas. I have the same issue as OP and going to try and figure it out tonight.

The display of iPhone 8 and iPhone 7 is not the same, here is the comparison video https://youtu.be/KxFovnbcY3E.

For this issue, my opinion is hard reset the iPhone to have a try.
