Hi,
Screen replacement – I'm using a brand-new screen now, so I can see everything clearly. The original broken screen was still working (except for the bottom part), but I tested with it again, and same issue. So, the screen isn't the problem.
MT version missing – I checked System Information, and the trackpad isn't detected. I've attached a screenshot.
Photos of UT360 & UT320 – Here are the pics of the replaced components, let me know if anything looks off.
Cables – Double-checked, they're fully seated and properly inserted....
