Customer put a iPhone 7 Plus LCD on a iPhone 8 Plus… Now iPhone 8 Plus only responds to iPhone 7 Plus LCD…. What could Be going on? Motherboard?

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.

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.
