SP3 Screen Replacement

i have tried three replacement screens on two different motherboards and all three appear to be dead (or both motherboards have identical errors that were not present when I disassembled the tablets).

The screen image in each case is displaying properly on an external monitor and Windows is reporting that there are two screens attached. But there is never an image on the tablet screen (with or without the external monitor connected, and obviously with the secondary display set to duplicated).

I've tried new display flex cables too.

is it plausible that some error has identically developed on both motherboards? if so any idea what that could be and where on the board I could test the logic levels to see?

any other ideas?
